NUMBUZIN NO.9 NAD+ COLLAGEN UNDER EYE PATCHES 5EA
NUMBUZIN No.9 NAD+ Collagen Under Eye Patches are single-use hydrogel patches built on Niacinamide, Adenosine, caffeine, and a hydrolyzed fish-collagen and peptide complex, worn 15-20 minutes to temporarily cool, hydrate, and de-puff the thin under-eye area β like a damp cloth after a bad night's sleep, but active-infused. They cannot lift sagging skin or fade true pigmented dark circles. Skip these if you have a known fish or carmine (cochineal) allergy, or if you specifically need a vegan formula.

100% Genuine Β· Fragrance-Free Β· Halal-Friendly* Β· Pregnancy-Safe* Β· Wudu-Compatible* (see the Wudu section below for what "compatible" means for a removable patch) β asterisked badges are footnoted in the relevant section, not certified claims.
| Attribute | Detail |
|---|---|
| Brand | numbuzin (No.9 line) |
| Product Type | Under-eye hydrogel patch, single-use pair |
| Net Volume | 5 pairs (10 patches) per box |
| Key Active | Niacinamide + Adenosine (concentration not brand-disclosed; both positioned in the INCI at levels consistent with a real dose) |
| Skin Types | All β patch test first (see Safety section) |
| Primary Concern Targeted | Under-eye puffiness, fine dehydration lines, dullness |
| AM/PM Suitability | Both β 15-20 min AM before makeup, or overnight for intensive hydration |
| Routine Complexity | Straightforward |
| MFDS Classification | Not independently confirmed (plausible functional-grade Niacinamide/Adenosine, but no registration verified this pass) |
If your under-eyes look tired even after a full night's sleep, that's usually fluid retention and thinning skin showing the blood vessels underneath β not a sign you need a stronger product, just a cooling, de-puffing one at the right moment.
Pigmentation note: "Dark circles" can mean brown pigment (PIH-like, responds to Niacinamide over weeks) or a blue-grey shadow from visible blood vessels through thin skin (a structural/vascular issue niacinamide does not fix). This patch's Niacinamide addresses the first type only β if your circles are more blue-grey than brown, expect the cooling and de-puffing effect, not a color change.
Pros: genuine cooling/de-puffing sensation on application; simple 15-20 minute single step with no rinsing; fragrance-free; contains real, position-plausible Niacinamide and Adenosine.
Caveats: not vegan (fish-derived collagen, carmine); the brand's headline NAD+/peptide/collagen actives sit deep in the ingredient list at likely trace concentrations (see the Fairy Dusting note in Ingredient Transparency); the widely-quoted 106.51%/108.69% clinical figures could not be traced to a named study this pass.
Age and Tween Suitability (Parental Guide)
Classification: GREEN β no exfoliating acids, retinoids, or benzoyl peroxide are present. Niacinamide, Adenosine, and caffeine at the concentrations implied by this INCI are cosmetic-grade, not clinical-strength actives that require a minimum age.
That said, under-eye patches like this one are a "treatment" gesture more than a skincare necessity for a teenager β a plain, unscented moisturizer covers most tween skin needs. There is no youth-targeted packaging or marketing on this SKU, so no packaging-trap warning applies here.
Low-Energy and Burnout Viability (For tough days)
Compatibility checklist: Bedside-compatible (yes, no sink needed) Β· Requires rinsing (no) Β· Requires precise dosage (no, one patch pair) Β· Usable with unwashed hands (yes, patches are handled by the edges) Β· Requires wait time (yes, 15-20 minutes) Β· Can be a single-product routine (yes, for that session).
This qualifies as a genuine minimum-viable-effort product: open the box, press two patches under your eyes, lie down or continue your routine around them, then peel off and pat in the residue. On a low-energy night, skip everything else and just do this plus a barrier moisturizer.
Sensory note: reviewers describe the gel as dewy rather than sticky, but some report the patches sliding if the skin underneath is very oily or sweaty β pat the under-eye area dry first if you're using this after a hot Mauritius afternoon.
Quick Start (60-Second Essentials)
Step 1 (When): AM before makeup for a quick de-puff, or PM/overnight for intensive hydration β both are valid uses.
Step 2 (How much): One patch under each eye, applied to clean, dry skin.
Step 3 (How): Press gently from the inner corner outward so the patch sits flat against the under-eye contour; avoid stretching it, which can crease the gel and reduce contact.
"Introduce this as the ONLY new product in your routine. Wait a full 14 days before adding anything else. This isolation window ensures you can identify whether any reaction is caused by this specific product."
AM Routine Guide (Morning sequence)
1. Gentle cleanse (if needed) β 2. Hydrating toner β 3. Apply the No.9 NAD+ Collagen Under Eye Patches for 15-20 minutes while you finish the rest of your routine β 4. Remove patches, massage in the remaining serum β 5. Eye cream (optional, if not already delivered enough hydration) β 6. Moisturizer β 7. Sunscreen SPF50+ PA++++.
Mauritius humidity note: humectants like the Glycerin and Hyaluronic Acid complex in this patch's gel draw moisture from the humid morning air rather than pulling it from deeper skin layers β one reason the cooling, plumped feel is genuinely stronger on a humid morning than in an air-conditioned room.
PM Routine Guide (Evening sequence)
1. Double cleanse β 2. Hydrating toner β 3. Treatment serum/actives (if any, on non-eye-area skin) β 4. Apply the No.9 patches for 15-20 minutes, or leave on overnight for intensive care β 5. Remove and massage in residue β 6. Eye cream (only one, not stacked with the patch's own residue on the same night if your skin runs sensitive) β 7. Moisturizer.
This patch does not occupy a retinoid, acid, or Vitamin C "lane" (see Ingredient Transparency), so it does not need to be scheduled around other actives the way an exfoliant or retinol would β it can be used the same night as most of your existing PM routine.
How to Use (Amounts, technique, and tips)
| Area | Amount |
|---|---|
| Under each eye | 1 patch per eye (1 pair per session) |
Technique: apply to clean, dry skin, pressing (not rubbing) from the inner corner outward. After removal, pat and massage the remaining serum into the skin rather than wiping it away or rinsing it off.
Required skin state: clean and dry β oily or damp under-eye skin reduces the patch's grip and is one reason some reviewers reported slipping.
Wait time: 15-20 minutes for a standard session; some listings describe overnight wear for intensive hydration. There is no pH-dependent chemistry here requiring a specific wait window β the timing is about how long the hydrogel needs to fully transfer its water and actives into the skin.
Hands vs. tools: use clean fingertips only to place and remove the patches; no applicator is needed or provided.
Routine Encyclopedia (Where every product type fits)
This is an encyclopedia map of all product types. You do not use all of these daily. You select modules based on your skin state.
Global execution rules: Viscosity ladder β thinnest to thickest, water-phase before oil-phase, treatments before seals. Wait-time defaults β watery layers 10-20s, serum layers 30-60s, before sunscreen 10-15 minutes if going outdoors or applying makeup. Amount defaults (unless brand-specific instructions override): watery toner/essence 5-8 drops per layer; serum/ampoule 2-3 drops or 1 pump; eye product Β½ rice-grain per eye; gel moisturizer 1-1.5 peas, cream 1-2 peas; occlusive seal rice-grain to pea-size max; sunscreen 2-finger rule for face plus 1 finger for neck. Skin state rules: hydrators best on slightly damp skin, retinoids best on fully dry skin, exfoliating acids on dry or lightly damp skin, keeping to one lane. Hard cap rule: if the routine pills, stings, or feels heavy, reduce layers, not increase.
AM Maximum Stack: 1. Rinse/Gentle Cleanse (optional) β 2. pH-Prep/Balancing Toner (optional) β 3. Hydrating Toner Layers (optional) β 4. Essence (optional) β 5. Mist/Thermal Water (optional) β 6. Booster/Soothing Serum (optional) β 7. Antioxidant Lane (choose one) β 8. Pigment Support Lane (choose one) β 9. Hydration Serum Lane (optional) β 10. Oil-Control/Sebum-Regulating Lane (optional) β 11. Peptides/Growth-Factor/Repair Lane (optional) β 12. Eye Patch/Eye Serum/Eye Cream (Β½ rice-grain per eye if a cream; this product replaces that step when used) β 13. Moisturizer β 14. Optional Sealing Layer (if dry/AC) β 15. Sunscreen SPF50+ PA++++ (non-negotiable) β 16. Lip SPF (optional).
"In AM, prioritize comfort + SPF adherence over stacking. In high humidity, fewer layers often perform better."
PM Maximum Stack: 1. Micellar (optional pre-cleanse) β 2. Oil Cleanser/Balm (if SPF/makeup) β 3. Water Cleanser β 4. pH-Prep Toner (optional) β 5. Hydrating Toner Layers (optional) β 6. Essence (optional) β 7. Soothing/Barrier Serum (optional) β 8. [Anchor Product] β 9. Targeted Serum (optional, only if non-conflicting) β 10. Moisturizer β 11. Sleeping Mask (optional) β 12. Occlusive Seal (optional) β 13. Spot Treatment/Pimple Patch (as needed) β 14. Lip Sleeping Mask (optional). This eye patch sits at the eye-treatment position, typically applied right after your hydrating toner/essence step and before moisturizer.
"Do not layer retinoids with AHA/BHA in the same night; keep 'one lane' per night."
Lane strictness: One-lane rule β Retinoid OR Exfoliation OR Strong Vitamin C (LAA) OR Acne-control active per routine; barrier/hydration can always accompany. If unsure, default to the safest lane β barrier/hydration β and reduce layers.
Viscosity and Layering Science (Where it fits)
Tier: This sits outside the normal water-to-cream ladder because it's a leave-on-then-remove patch, not a layered product β apply it after your watery toner/essence step and before your moisturizer, since the patch's own gel is roughly essence-weight.
Layering rule: apply to freshly toned, still-slightly-damp skin so the hydrogel bonds evenly; follow with moisturizer after removal to seal in what the patch delivered.
Molecular weight context: NAD+ has a well-established molecular weight of roughly 663 Da β well above the ~500 Da threshold generally used as a rule-of-thumb ceiling for meaningful penetration through intact stratum corneum. This means NAD+ in this formula most plausibly acts on the skin surface and within the very outer layers during the 15-20 minute wear, rather than penetrating to reach living dermal cells β consistent with treating it as a supportive, surface-level ingredient rather than the "collagen-boosting" internal mechanism implied by marketing.
Phase compatibility: water-phase, silicone-free (no dimethicone or related silicones detected in the retrieved INCI) β layers cleanly under a water-based moisturizer without pilling from a silicone mismatch.
Weekly Planner (Scheduling actives)
| Day | Use |
|---|---|
| Mon / Wed / Fri | Patch session (AM before an event, or PM) |
| Tue / Thu / Sat / Sun | Standard eye cream only |
There is no safety-driven frequency cap here β this isn't an acid or retinoid β but 2-4 sessions a week is the realistic, sustainable cadence most reviewers describe, since a box holds only 5 pairs. Daily use is not required for the cooling/de-puffing effect to register; save it for mornings after poor sleep, travel, or salty/dehydrating days.
Overuse note: using the patches daily does not accelerate long-term firming results, since the headline actives (NAD+, collagen, peptides) sit at trace concentrations β it mainly just uses up the box faster for the same in-the-moment cooling benefit.
What to Expect (Results timeline)
| Phase | Timeframe | What You Will Notice |
|---|---|---|
| Immediate | 0-20 minutes | Cooling sensation, visible plumping/hydration under the eyes β transient, from water and caffeine, not structural change |
| Same day | Within hours | De-puffing effect fades gradually as the skin reabsorbs and evaporates the surface hydration; makeup typically applies more smoothly right after use |
| Adjustment | Week 1-2 | No expected irritation given the gentle formula; discontinue if any stinging or redness persists beyond a few minutes |
| Consistent use | Week 4-6 | Reviewers most often describe improved comfort/hydration and reduced morning puffiness with 2-3x/week use over a month, rather than a dramatic wrinkle change |
| Maintenance | Ongoing | Effect plateaus at "consistent de-puffing/hydration tool" β it does not compound into permanent firmness, since the box is finite and the headline actives are trace-level |
Who Should Use This (Clinical triage)
Prerequisites: None β this is a low-risk, occasional-use product that does not require a pre-existing routine or healthy-barrier baseline to use safely.
PROCEED IF: you want a quick de-puffing/cooling treatment before an event, after a poor night's sleep, or as an occasional hydration boost, and you have no known fish or carmine allergy.
PAUSE IF: you're currently reacting to another new product β per the One Rule above, don't introduce this alongside it.
STOP/CONSULT IF: you have a diagnosed fish allergy (this product contains fish-derived collagen) or a known carmine/cochineal sensitivity β patch test on your inner forearm first regardless.
Skin Type Compatibility
| Skin Type | Compatibility | Notes |
|---|---|---|
| Oily | Suitable | Fragrance-free, non-comedogenic base ingredients; the cooling effect is a nice contrast to Mauritius heat |
| Dry | Suitable | Glycerin/Hyaluronic Acid complex delivers real surface hydration; follow with moisturizer to lock it in |
| Combination | Suitable | No area-specific restriction; under-eye skin behaves similarly regardless of T-zone oiliness |
| Sensitive | Suitable with caution | Fragrance-free is favorable, but the FA-conditional emulsifiers and colorant load (see Allergens section) mean a patch test is worth doing |
| Mature | Suitable | Adenosine at a plausible functional-level position is the most evidence-backed ingredient here for fine lines; manage expectations on the collagen/NAD+ claims |
Targeted Concerns (What it treats)
Under-eye puffiness: Caffeine has documented vasoconstrictive and mild diuretic-adjacent topical effects that temporarily reduce visible fluid pooling; the cooling hydrogel format itself also reduces swelling the way a cold compress does.
Fine dehydration lines: The Glycerin/Hyaluronic Acid/Sodium Hyaluronate humectant complex plumps the very thin under-eye skin with water, temporarily smoothing the look of fine lines caused by dehydration (not deep, etched wrinkles).
Dullness: Niacinamide, positioned early enough in the INCI to plausibly be at a real dose, is a well-evidenced ingredient for improving overall skin tone evenness over consistent use.
What this product cannot do: it cannot physically lift sagging under-eye skin, cannot remove structural (vascular or bony-shadow) dark circles, and cannot deliver a lasting collagen-remodeling effect from a 15-20 minute occasional patch β those require sustained daily actives or in-clinic treatment.
Best Paired With (Synergistic pairings)
Follow-up eye cream (for daily continuity): Primary β numbuzin No.9 NAD Retinol Volumetox Eye Cream 10ml, from the same No.9 line, to carry the hydration forward on non-patch days. Alternatives: numbuzin No.9 NAD+ Retinal Volumetox Eye Cream 20ml (stronger, retinal-based β see the Conflict note below), goodal Green Tangerine Vita C Eye Gel Patch, PETITFEE Black Pearl & Gold Hydrogel Eye Patch.
AM sunscreen (mandatory pairing, since this patch offers no UV protection): Primary β numbuzin No.1 Clear Filter Sun Essence SPF50+ PA++++. Alternatives: numbuzin No.9 NAD+ 9 Peptides Dewy Sun Essence, SKIN1004 Madagascar Centella Hyalu-Cica Water-Fit Sun Serum 50ml, numbuzin No.3 Porcelain Base-skip Tone Up Beige SPF50+ PA++++ (limited stock β check availability).
Same-line toner/essence: Primary β numbuzin No.9 NAD PDRN Glow Boosting Toner 150ml. Alternatives: numbuzin No.9 NAD Bio Lifting Essence 50ml, numbuzin No.3 Super Glowing Essence Toner 200ml, numbuzin No.2 Rose PDRN Collagen Plumping Serum 30ml.
Pilling pairs: Low pilling risk with most water-based serums and creams since this patch's residue is a simple humectant gel. If you use a heavy occlusive balm eye cream directly after removing the patch without letting the residue absorb, expect some product to bead β wait 60 seconds before layering a thick cream.
Stress, Cortisol and Your Skin
Chronic stress and poor sleep elevate cortisol, which increases fluid retention and dilates the fine blood vessels visible through thin under-eye skin β a real, physiological reason under-eyes look worse after a stressful week, not just "looking tired" as a figure of speech.
This patch's caffeine and cooling hydrogel address the visible symptom (fluid, vasodilation) in the moment; they do not lower cortisol itself. If under-eye puffiness is a near-daily pattern rather than an occasional post-bad-night issue, the more durable fix is sleep and stress management β this product is a same-day tool, not a root-cause one.
Wudu and Prayer Compatibility
Permeability: Water-Permeable, with a caveat β the patch itself is a physical hydrogel piece removed before ablution (it is not left on the skin during wudu), and the serum residue massaged in afterward is a water-based, silicone-free formula (no film-forming silicones or waxes detected in the retrieved INCI), so it does not block water contact with the skin.
Removal method: peel the patch off from the outer edge before wudu if you're still wearing it; no special removal is needed for the absorbed residue.
"Adilsons provides this assessment based on the product's physical properties. Rulings on wudu validity vary between scholars. Consult your own trusted Islamic authority."
Myth Replacement (Common misconceptions)
MYTH: "Under-eye patches with NAD+ and collagen physically boost your body's own collagen production." REALITY: the collagen in this patch is a topical, hydrolyzed (broken-down) fragment applied at a trace concentration by INCI position β it hydrates and sits on the surface, it does not integrate into your skin's own collagen matrix or trigger meaningful new collagen synthesis from a 15-20 minute application.
MYTH: "A more dramatic before/after (like the widely-quoted 106.51%/108.69% figures) means a more effective product." REALITY: a percentage improvement over 100% on a physical measurement is itself a signal to look for the underlying methodology before trusting the number β no testing institution or sample size was found for this specific claim during this research pass, so it is presented here as an unverified marketing figure, not a confirmed clinical result.
MYTH: "Eye patches can permanently fix dark circles." REALITY: circles caused by visible blood vessels through thin skin (a structural trait, sometimes genetic) do not respond to any topical ingredient, including this one β only pigmented (brown) dark circles have a realistic topical treatment path.
Climate Fit for Mauritius
| Season | Conditions | How to Adjust |
|---|---|---|
| Summer (Dec-Mar) | High heat and humidity, more sweat | Pat under-eye skin fully dry before applying so the patch grips instead of sliding; the cooling effect will feel especially good in this season |
| Winter (Jun-Sep) | Cooler, drier air, more AC use | Follow patch removal with a proper moisturizer promptly β AC dries out the humectant hydration faster |
| Cyclone Season (Jan-Mar) | High humidity swings | No change needed; the gel format performs consistently regardless of ambient humidity, unlike a leave-on humectant serum |
AC environment warning: in air-conditioned environments, the Hyaluronic Acid and Glycerin in the patch's residue can pull moisture from your deeper skin layers instead of from the air once the room is dry enough β always seal the residue with a moisturizer if you'll be in AC for hours after use.
Sugar cane burning season (July-November): PM2.5 increases during this period. This patch's dewy (not tacky) finish means it doesn't meaningfully increase particulate adhesion, but its Resveratrol and Ascorbic Acid (trace-level antioxidants) provide a small supportive benefit against oxidative pollution stress if used in the morning.
Complete Ingredient Transparency
| Ingredient | Evidence Grade | Mechanism | Source |
|---|---|---|---|
| Niacinamide | Strong | Improves tone evenness, supports barrier function, positioned above the estimated 1% line | Synthetic (Vitamin B3 derivative) |
| Adenosine | Strong (at MFDS-relevant concentrations) | Supports the appearance of fine-line smoothing | Synthetic |
| Caffeine | Moderate | Vasoconstrictive, temporarily reduces visible puffiness/fluid | Synthetic/plant-derived |
| Hydrolyzed Collagen (fish-derived, per retailer marketing) | Emerging* | Surface humectant film; plausibly trace-level by INCI position | Marine (fish) |
| NAD+ / ATP / Resveratrol / Glutathione | Emerging* | Antioxidant/cellular-cofactor ingredients, plausibly trace-level by INCI position | Synthetic/biotechnological |
| Sodium Hyaluronate / Hyaluronic Acid complex | Strong | Humectant, draws and holds water at the skin surface | Fermentation-derived |
*Emerging evidence grade: real ingredient presence confirmed via INCI, but positioned below the estimated 1% line, suggesting a trace/sub-efficacious concentration for this specific product. Its inclusion may be primarily for marketing rather than clinical effect.
Full INCI list (source: WebSearch aggregation of a third-party INCI listing; the underlying retailer/brand pages were blocked for direct verification this session β see Open Questions in our research notes): Water, Glycerin, Butylene Glycol, Niacinamide, Chondrus Crispus Extract, 1,2-Hexanediol, Chondrus Crispus, Hydroxyacetophenone, Ceratonia Siliqua (Carob) Gum, Agar, Allantoin, Sucrose, Ultramarines, Ethylhexylglycerin, Adenosine, Dipotassium Glycyrrhizate, Maltodextrin, Potassium Chloride, [--- Estimated 1% Line ---] Polyglyceryl-10 Laurate, Polyglyceryl-10 Myristate, Benzophenone-4, Titanium Dioxide, Calcium Aluminum Borosilicate, Caffeine, Sodium Citrate, Calcium Titanium Borosilicate, Synthetic Fluorphlogopite, Dipropylene Glycol, Methyl Diisopropyl Propionamide, Sodium Hyaluronate, Carmine, Tin Oxide, Hydrolyzed Collagen, Propanediol, Ferric Ferrocyanide, Hyaluronic Acid, Hydrolyzed Hyaluronic Acid, Ascorbic Acid, Polyglyceryl-6 Laurate, Caprylic/Capric Triglyceride, Hydrogenated Lecithin, Adenosine Triphosphate, Nicotinamide Adenine Dinucleotide, Resveratrol, sh-Octapeptide-4, sh-Decapeptide-7, Acetyl Hexapeptide-8, Glutathione, Oligopeptide-29, Oligopeptide-32, Palmitoyl Pentapeptide-4.
This list is confirmed partial β one retail source referenced approximately 98 total ingredients, meaning the true list very likely continues beyond what's shown here, particularly for the brand's "50 types of peptides" claim (only 6 individually-named peptides were found). We state this plainly rather than filling the gap with invented ingredient names.
Fairy dusting callout: NAD+, ATP, Resveratrol, Glutathione, and Hydrolyzed Collagen β the entire marketing identity of this product β all sit below the estimated 1% line by INCI position. *These ingredients appear below the estimated 1% line in the INCI list, suggesting they are present at trace/sub-efficacious concentrations. Their inclusion may be primarily for marketing rather than clinical effect.
Preservative system: 1,2-Hexanediol and Ethylhexylglycerin β a mild, paraben-free antimicrobial/preservative-boosting pair commonly used in Korean formulas as an alternative to traditional parabens or phenoxyethanol.
Allergens and Fragrance Disclosure
Fragrance status: Fragrance-Free β no Parfum/Fragrance ingredient detected in the retrieved INCI.
Scent: No detectable added scent expected; any faint odor from the marine-derived collagen or ferment-adjacent extracts is normal, not spoilage.
EU 26 allergen screen: None detected in the declared INCI reviewed this pass.
Alcohol disclosure: Alcohol-Free β no ethanol-type "Alcohol" or "Alcohol Denat." found in the retrieved INCI.
Cross-Reactivity and Drug Interactions
Fish allergy: this product contains Hydrolyzed Collagen described by multiple retailers as fish-derived β if you have a diagnosed fish allergy, patch test carefully or avoid, since the origin was not independently confirmed via a certificate but is consistently described this way across sources.
Carmine (cochineal) sensitivity: Carmine, an insect-derived red colorant, is present for the patch's purple/glitter tint. Carmine allergy is uncommon but documented, particularly in people with prior reactions to cosmetic red pigments β patch test if you have a known sensitivity.
Conscious and Permissible Formulation
Halal: *Self-assessed by Adilsons based on available INCI data. No ethanol from fermentation and no porcine-derived ingredients detected in the declared ingredient list. This is NOT a formal Halal certification. Muslims with stricter requirements should consult their own scholars, particularly regarding the insect-derived Carmine colorant.
Vegan: No. This product contains Hydrolyzed Collagen (fish-derived, per retailer marketing) and Carmine (cochineal, insect-derived) β both animal-derived ingredients. It cannot be marketed as vegan.
Cruelty-free: *Brand-stated policy. Not independently certified by Leaping Bunny, PETA, or equivalent third-party audit. numbuzin's Mainland China retail presence was not resolved this pass, so the China Retail Caveat is noted as an open question rather than confirmed either way.
Microplastic-Free: Yes β the colorant/shimmer system is mineral-based (Ultramarines, borosilicates, Synthetic Fluorphlogopite, Titanium Dioxide), not plastic microbead.
Evidence, Regulation and Claims
MFDS classification: Not independently confirmed as Functional Cosmetic via a primary registry this pass, though Niacinamide and Adenosine are both real MFDS functional-ingredient categories in Korea (brightening and wrinkle-improvement respectively) at plausible concentrations.
Whitening translation: Korea's "λ―Έλ°±" (mibaek) classification for Niacinamide-type ingredients means regulation of melanin production β fading existing dark spots or brown-toned discoloration to reveal your natural tone. It does NOT bleach skin or lighten your natural complexion, and it does not address blue-grey (vascular) under-eye shadowing.
Clinical evidence: the widely-repeated "106.51% puffiness reduction / 108.69% wrinkle improvement" figures could not be traced to a named institution, sample size, or methodology in any source found this pass. *Evidence confidence: Marketing-Only. This claim is repeated across multiple retailer listings but no underlying study data, sample size, or testing protocol has been disclosed.
Product Identity and Provenance
| Field | Detail |
|---|---|
| English Name | NUMBUZIN No.9 NAD+ Collagen Under Eye Patches |
| Korean Name | Not independently confirmed this pass |
| Brand / Line | numbuzin, No.9 (NAD+/Peptide anti-aging line) |
| Country of Manufacture | South Korea (consistent with brand HQ; not independently confirmed via a specific certificate this pass) |
| Net Volume | 5 pairs (10 patches) per box; approximately 8g per pair per one retailer listing (medium confidence) |
| PAO / Shelf Life Unopened | Not publicly disclosed |
Sensory and Chemical Profile
| Attribute | Detail |
|---|---|
| Texture | Hydrogel/jelly patch, described by reviewers as dewy, not sticky |
| Viscosity | Firm gel (holds shape as a patch, not pourable) |
| pH | Not publicly disclosed |
| Absorption Speed | Residue absorbs within roughly 1-2 minutes of massaging in after patch removal |
| Finish | Dewy, slightly tacky immediately after removal, settling to a normal finish within minutes |
Fungal Acne Safety: FA-Conditional. Polyglyceryl-10 Laurate, Polyglyceryl-10 Myristate, Polyglyceryl-6 Laurate, and Hydrogenated Lecithin are all emulsifiers with fatty-acid ester chain lengths in the range some Malassezia-feeding databases flag as conditional. This is applied only to the thin under-eye area, so risk is lower than a leave-on face-wide product, but FA-prone users should monitor for small bumps after repeated use.
Pilling Risk and Texture Mechanics
Assessment: Low. The residue is a simple humectant gel without heavy silicones or waxes.
Pilling is more likely if you apply a thick, occlusive eye balm immediately after removing the patch, before the residue has absorbed β wait about 60 seconds and pat, don't rub, when layering the next product.
Stability, Spoilage and Oxidation
Color baseline: the patches are intentionally purple/glittery from cosmetic colorants β this is a designed color, not an oxidation indicator. A genuinely spoiled patch would show browning, a sour or off smell, or visible mold/discoloration unrelated to the purple tint.
Storage: keep the box in a cool, dry place away from direct bathroom humidity and heat β Mauritius bathroom humidity can accelerate gel breakdown in an opened box faster than a sealed one.
Spoilage signs: a sour smell, visible separation of the gel from its backing, or a change in color unrelated to the designed purple/glitter tint. When in doubt, discard.
Safety and Patch Test Protocol
Patch test: apply a small piece of the hydrogel to your inner forearm for 24 hours, then behind the ear for 24 hours, before your first full under-eye application β this is especially worth doing given the fish-collagen and carmine content.
"If adverse reaction: STOP ALL ACTIVES. For 72 hours, use ONLY gentle cleanser + plain moisturizer + mineral SPF. NO acids, retinoids, Vitamin C, exfoliants, or essential oils. After 72h, reintroduce ONE product per 14 days."
Emergency stop signals: hives, swelling, blistering, persistent burning, or breathing difficulty β seek emergency care immediately and do not continue use.
Troubleshooting Guide
| If You Experience | Likely Cause | Solution |
|---|---|---|
| Patch slides down your face | Oily/damp under-eye skin, or over-application of other products first | Pat the area fully dry before applying; apply patches before any other eye product, not after |
| Stinging on application | Micro-abrasions from rubbing, or an individual sensitivity to a specific ingredient | Remove immediately if it doesn't subside within seconds; patch test on the forearm first next time |
| No visible de-puffing effect | Puffiness from a non-fluid cause (fat pad prominence, genetics) rather than transient fluid retention | This product only addresses fluid-driven puffiness; structural puffiness needs a different (often in-clinic) approach |
| Sticky residue that won't absorb | Too much product left on, or moisturizer applied before the gel finished absorbing | Massage in fully for a full minute before moving to the next step |
Common Mistakes to Avoid
1. Applying to wet or oily skin β reduces grip and increases the odds of the patch sliding.
2. Stretching the patch to fit β creases the gel and reduces even skin contact; press gently into place instead.
3. Expecting a permanent lift β the de-puffing effect is real but temporary, from hydration and caffeine, not structural change.
4. Using it as a substitute for daily eye cream β with only 5 pairs per box, this is an occasional-use treatment, not a daily-hydration replacement.
5. Wearing the patches while lying on a pillow β the shimmer colorant and gel can transfer to fabric if you doze off with them on; use a spare pillowcase or stay upright for overnight wear if this concerns you.
Overuse threshold: there's no safety-driven maximum, but using more than one box's worth per week provides no additional benefit given the trace-level headline actives β it simply depletes the box faster.
Usage Economics (How long it lasts)
Usage math: 5 pairs (10 patches) per box, one pair per session.
Lifespan: at a realistic 2-3 sessions per week, one box lasts roughly 2-2.5 weeks; using it daily depletes a box in under a week without adding proportional benefit, since the results plateau at "consistent de-puffing tool" rather than compounding.
Reorder timing: if you use this 2-3x/week, plan to reorder with about a week of buffer before you run out, to account for Mauritius delivery timing.
Complete Your Routine (Exact routine + pairings)
This patch is an occasional-use booster, not a daily routine anchor β it slots into an existing AM or PM routine at the eye-treatment step, right after toner/essence and before moisturizer.
AM: 1. Cleanse (if needed) β 2. Toner β 3. Eye patch, 15-20 minutes, worn while finishing the rest of the routine β 4. Massage in residue β 5. Moisturizer β 6. Sunscreen SPF50+ PA++++.
PM: 1. Double cleanse β 2. Toner β 3. Treatment serum (non-eye-area) β 4. Eye patch, 15-20 minutes or overnight β 5. Massage in residue β 6. Moisturizer.
If you're prepping for an event with no sleep the night before: use the patches first thing, 20 minutes before makeup, for the strongest visible de-puff.
If you're in AC most of the day after using this: seal the residue with a proper moisturizer immediately β don't let the humectants sit exposed to dry AC air.
If you're also using a retinal-based eye cream (like numbuzin's own No.9 NAD+ Retinal Volumetox Eye Cream) in the same routine: use the patch and the retinal cream on different occasions rather than layering both in one session β the thin eye area doesn't need two active-forward treatments stacked at once.
Stock-true bundle idea: pair with numbuzin No.9 NAD PDRN Glow Boosting Toner and numbuzin No.1 Clear Filter Sun Essence SPF50+ for a complete same-line AM routine β toner for hydration, patch for the eye area, sunscreen to close.
After purchasing, you will receive our skincare education email series covering this product in depth.
The recommendations above are based on formulation synergy with numbuzin No.9 NAD+ Collagen Under Eye Patches, not on margin or stock levels. If a pairing does not exist in our catalog, we say so. If you already own a product that fills the same role, use what you have first.
Is This the Best Choice? (Mindful alternatives)
If you want a similar cooling/hydrating eye-patch effect without fish collagen or carmine, or at a different format/price point, we carry: Primary β PETITFEE Black Pearl & Gold Hydrogel Eye Patch (60EA/30 pairs), a larger-count hydrogel patch built around pearl/gold cosmetic actives rather than a collagen/NAD+ story. Alternatives: goodal Green Tangerine Vita C Eye Gel Patch (Vitamin C-focused, brightening-forward), PETITFEE Agave Hydrogel Eye Patch (simple hydration-focused), Beauty of Joseon Revive Under Eye Patch (ginseng/retinal-adjacent anti-aging positioning).
Why Choose This Over the Alternative?
Choose numbuzin's No.9 patch over the PETITFEE Black Pearl & Gold if you need a real, position-plausible Niacinamide/Adenosine dose alongside the cosmetic shimmer, since PETITFEE's format leans more purely cosmetic/mineral-based per its own marketing positioning.
| Upgrade Axis | What's better in THIS | What you trade off | Who benefits |
|---|---|---|---|
| Active dose density | Real Niacinamide + Adenosine above/near the estimated 1% line | Fewer patches per box (5 pairs vs. 30 pairs) | Anyone prioritizing ingredient function over pack count |
| Pack count / session economy | β | 5 pairs vs. PETITFEE's 30 pairs β this box runs out roughly 6x faster at the same frequency | Occasional users who don't mind reordering more often |
| Vegan status | β | Contains fish collagen + carmine (not vegan) | PETITFEE's alternative may suit vegan shoppers better β verify its own INCI before assuming, though |
IF you specifically want the Niacinamide/Adenosine functional pairing, THEN this product is the better fit despite the smaller pair count.
IF you want more total patches for frequent, low-cost-per-use sessions and don't need the collagen/NAD+ story, THEN the PETITFEE alternative's larger 30-pair count may suit you better.
IF you have a diagnosed fish or carmine allergy, THEN skip this product entirely and choose the PETITFEE, goodal, or Beauty of Joseon alternative instead β verify each one's own INCI first rather than assuming any of them is automatically allergen-free.
IF you specifically need a vegan-formulated eye patch, THEN do not default to this product β check the alternative's own INCI, since "not this one" is confirmed but "definitely vegan" for the alternative is not yet verified here.
IF you're prepping for a same-day event and want the strongest immediate cooling/de-puffing sensation, THEN either hydrogel format works similarly well β this axis does not meaningfully differentiate the two.
IF you're currently mid-way through an open box of any other eye patch, THEN finish that one first regardless of which of these two you'd otherwise pick β see the No-Buy Redundancy Check below.
Don't upgrade to this one if: you need a strictly vegan formula (choose an alternative and verify its INCI); you have a diagnosed fish or carmine allergy; you only want the lowest cost-per-session option, since the smaller pair count here means a shorter box life for the same session frequency; you already own an unfinished box of a comparable eye patch.
If you match the active-ingredient priority above, this is worth choosing. If not, the alternative is sufficient and simpler. Consistency in your eye-area routine beats chasing the newest patch.
Graduation Pathway
This occasional-use patch is the "entry point" for eye-area care. If you find you want daily, continuous support rather than occasional treatment sessions, the natural next step in-catalog is numbuzin No.9 NAD Retinol Volumetox Eye Cream for daily use, and β once your skin has built tolerance to retinoids elsewhere in your routine β numbuzin No.9 NAD+ Retinal Volumetox Eye Cream for a stronger, retinal-based daily option.
The No-Buy Redundancy Check
This product's PRIMARY function is: occasional, fast-acting under-eye de-puffing and hydration. You do NOT need this if you already own an unopened box of a similar hydrogel eye patch with a comparable humectant/caffeine base β finish that first.
Inventory audit: check whether you already have an open box of any eye patch (this or a different brand) before buying β with only 5 pairs per box and no strict PAO requirement driving urgency, there's little reason to run two boxes at once.
Stacking assessment: No Benefit if you're already using another Niacinamide/Adenosine-based eye patch β same mechanism, redundant purchase. Significant Benefit if your current eye routine has no dedicated de-puffing tool and relies only on a standard eye cream, since the occlusive patch format and caffeine content are a genuinely different delivery mechanism.
Sourcing and Authenticity
This product is sourced through authorized Korean distributors β primarily Craver Co., Ltd (South Korea), alongside other verified distribution partners. Craver is a major Korean beauty distributor and the parent company of SKIN1004, handling authorized distribution for multiple K-beauty brands. All products are shipped directly to Mauritius via verified channels.
For comprehensive information about how we verify authenticity, our layered verification system, and how to check your product at home, visit our dedicated Authenticity and Trust page.
Quick check: confirm the outer box shows the numbuzin branding and "No.9" line naming consistent with official listings, and that the batch/lot code is legible on the box β if anything looks inconsistent, our Authenticity page has the full verification process.
About numbuzin
Brand: numbuzin. Founded: 2019, South Korea. Parent Company: none identified β an independent brand. Philosophy: "What's Your Number?" β a numbered product-line system (No.1 through No.9+) meant to match a product to a specific skin goal rather than parsing marketing names, with No.9 built around NAD+, peptides, and anti-aging positioning specifically.
numbuzin states a cruelty-free, no-animal-testing manufacturing policy, though this is brand-stated rather than third-party certified. The brand's numbered-line naming has been reused across genuinely different formulas over time (documented across multiple numbuzin SKUs in our research), so always verify you're looking at the exact current formula for any given "No." product rather than assuming line continuity.
Genuine Community Experiences
Independent review sources (an arktastic.com product-review blog post, and aggregated iHerb/Amazon review summaries) describe this as one of the pricier K-beauty eye patches on the market, with a genuinely comfortable, cooling, non-sticky application experience. One reviewer, testing multiple premium eye patches, noted the immediate de-puffing sensation was noticeable but the overall brightening/glow payoff was less pronounced than some competing patches β positioning it more as a hydration/fine-line tool than a radiance booster.
Feedback on staying power was mixed: some reviewers reported the patches gripping well through a 15-20 minute session, while others described them as thick and prone to sliding, particularly if the under-eye skin wasn't fully dry beforehand.
A recurring complaint across sources was value-for-money β 5 pairs per box was seen by several reviewers as a small count relative to the category's pricier positioning. We were not able to locate a dedicated Reddit r/AsianBeauty or r/SkincareAddiction thread specifically about this exact SKU during this research pass; the reviews above come from retailer/review-site summaries rather than a directly-read forum consensus.
Packaging and Practical Details
| Attribute | Detail |
|---|---|
| Primary Packaging | Box containing 5 pairs (10 patches); whether each pair is individually sealed was not independently confirmed this pass |
| Hygiene Rating | High β single-use, no risk of cross-contamination between sessions |
| Travel-Friendly | Yes β flat patches pack easily; not a liquid, so it avoids most carry-on liquid restrictions (verify with your specific airline) |
Sustainability: individual patch backings are typically a plastic film not designed for home recycling; check the outer box for any brand-specific recycling guidance, as none was independently confirmed this pass.
Frequently Asked Questions
How often should I use these? There's no safety-driven limit, but 2-3 sessions a week is a realistic, sustainable cadence β daily use empties the box faster without adding proportional benefit, since the results plateau quickly.
Do these actually reduce puffiness and dark circles? The cooling, temporary de-puffing effect from caffeine and hydration is real and well-supported by both ingredient science and reviewer reports. The specific 106.51%/108.69% clinical figures circulating online could not be traced to a named study this pass β treat them as an unverified marketing claim, not a confirmed result.
Can I use these under makeup? Yes β many reviewers use them 15-20 minutes before makeup application specifically because the residue absorbs and the skin looks temporarily smoother and less puffy, which helps concealer sit better.
Are these vegan or cruelty-free? No, not vegan β they contain fish-derived collagen and carmine (insect-derived colorant). The brand states a cruelty-free policy, but this is not independently third-party certified.
Can I use these with a retinol or retinal eye cream? Yes, but not in the same session β use the patch and a retinoid eye cream on different days or times, since stacking two active-forward eye treatments on the same thin skin at once increases irritation risk for no added benefit.

The Final Verdict
Best for: anyone who wants a quick, cooling, occasional pick-me-up for tired-looking under-eyes β before an event, after a bad night's sleep, or as a periodic treat within an existing eye-care routine.
Key benefits: genuine, immediate cooling and de-puffing sensation; real Niacinamide and Adenosine at plausible functional positions; fragrance-free, alcohol-free, silicone-free formula that layers cleanly.
Keep in mind: the headline NAD+/collagen/peptide story is trace-level by ingredient position, not the main event; it is not vegan due to fish collagen and carmine; and the widely-quoted clinical percentages should be read as marketing claims, not verified study results, until the brand discloses the underlying methodology.
Oncology and Treatment-Sensitized Skin
Assessment: Consult Oncologist. This formula is fragrance-free and retinoid-free with a minimal, mild preservative system, which is favorable β but it also contains a colorant/shimmer system (Carmine, Ultramarines, borosilicates) and a fish-derived collagen ingredient that have not been evaluated against oncology-specific sensitivity guidance in our research.
"Consult your oncology care team before introducing any new skincare products during treatment."
Environmental Defense and Lifestyle Factors
Antioxidant pollution defense: Resveratrol and Ascorbic Acid (Vitamin C) are both real, verified ingredients in this formula, though at trace-level concentrations by INCI position β they offer a small supportive antioxidant benefit against oxidative stress from sun and pollution exposure, not a primary defense mechanism.
AC/humidity swing interaction: the Glycerin/Hyaluronic Acid humectant base performs best when there's ambient humidity for it to draw from; in a long air-conditioned stretch after use, seal the residue with a moisturizer so it doesn't reverse-draw moisture from your own skin.
