Medicube RETINOL NMN BOOSTING SERUM 30ml

100% Genuine (Adilsons policy) · Fragrance-Free. Not claimed as Pregnancy-Safe (contains 1.9% Retinol — see safety notice above). Vegan status is tentative/self-assessed only (see Conscious Formulation section) since the recovered ingredient list is incomplete.

Watching fine lines settle in or noticing your skin looks "softer" in a way that isn't flattering is a specific, quiet kind of worry — it rarely feels urgent day to day, but it is exactly the kind of change that a well-managed retinoid routine is built to address over months, not days.

Pros: a genuinely disclosed, high 1.9% Retinol concentration (most K-beauty retinol serums do not disclose a %); triple-probiotic buffering system; fragrance-free; brand-cited multi-metric clinical claims. Caveats: a second undisclosed-dose retinoid (Retinal) is also present, meaning your total retinoid load is higher than the 1.9% headline number alone suggests; "irritation-free" brand marketing should not replace a standard slow introduction; institution name behind the clinical claims is inconsistent across sources.

Classification: RED. A 1.9% Retinol concentration, plus a second undisclosed-dose retinoid (Retinal), is a clinical-grade, advanced-tier active targeting collagen turnover and cell renewal processes that skin under 16 has not yet begun to need. This is not suitable for under-16 skin at any frequency.

Safe alternatives for younger users: a plain moisturizer with SPF is the appropriate "routine" for teenage skin with no active acne concern; if breakouts are the actual issue, a gentle salicylic-acid cleanser is a more age-appropriate starting point than a retinoid.

Step 1 (When): PM only, starting at 2 nights per week. Step 2 (How much): a pea-sized amount, roughly 2-3 drops for the full face. Step 3 (How): apply to fully dry skin (wait 10-15 minutes after cleansing if you have sensitive skin), then follow with moisturizer.

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.

This is a PM-only product — retinol is UV-unstable and photosensitizing, so daytime use offers no benefit and adds sun-sensitivity risk. AM routine instead: 1. Cleanse. 2. Antioxidant serum (optional). 3. Moisturizer. 4. Sunscreen SPF50+ PA++++ (non-negotiable, and doubly important the morning after any night you use this serum).

SPF mandate: retinoid use measurably increases photosensitivity for the following 24 hours; skipping SPF on those mornings risks sunburn and undoes any brightening/tone benefit the retinol is meant to deliver.

1. Double cleanse if wearing sunscreen/makeup. 2. Toner (optional). 3. Wait until skin is fully dry. 4. Medicube Retinol NMN Boosting Serum — a pea-sized amount, pressed in, not rubbed. 5. Wait 2-5 minutes if your skin is sensitive. 6. Moisturizer.

Skin cycling integration: this is your Night 2 "Retinoid" product in a 4-night cycle (Night 1 Exfoliation elsewhere, Night 2 this serum, Nights 3-4 Recovery, no actives). Do not run it alongside a separate AHA/BHA exfoliant on the same night.

Pat/press, do not rub — friction increases irritation with any retinoid. Required skin state: fully dry, not damp — retinol can penetrate too aggressively on damp skin and increase sting risk, the opposite rule from most hydrating serums. Wait time: 2-5 minutes before moisturizer if you are new to retinol or have reactive skin; established users can layer sooner.

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.

Viscosity ladder: thinnest → thickest; water-phase before oil-phase; treatments before seals. Wait-time defaults: watery layers 10-20s; serum layers 30-60s; retinoids on fully dry skin, wait 2-5 minutes if sensitive; before sunscreen 10-15 min if going outdoors. Amount defaults: toner/essence 5-8 drops; serum/ampoule 2-3 drops or 1 pump; gel moisturizer 1-1.5 peas; cream 1-2 peas; sunscreen 2-finger rule. Hard cap rule: if the routine pills, stings, or feels heavy, reduce layers, not increase.

AM Maximum Stack: 1-8. Standard cleanse-through-antioxidant-lane steps as needed (this product does not occupy an AM slot). 9. Hydration serum lane (optional). 13. Moisturizer. 15. Sunscreen SPF50+ PA++++ (non-negotiable). In AM, prioritize comfort and SPF adherence over stacking.

PM Maximum Stack: 1. Micellar pre-cleanse (optional). 2. Oil cleanser (if SPF/makeup worn). 3. Water cleanser, fully dry skin after if using retinoids. 4-7. Toner/essence/soothing serum as tolerated (optional). 8. [Anchor Product] — this serum, bold placement, fully dry skin, wait 2-5 minutes before moisturizer if sensitive. 9. Targeted serum (optional, ONLY if not conflicting — see Conflict Solver below). 10. Moisturizer. 11. Sleeping mask (optional, dry/barrier-support nights). 12. Occlusive seal (optional, avoid if clog-prone). Do not layer retinoids with AHA/BHA in the same night; keep "one lane" per night.

Lane strictness: Retinoid (this product) 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 and reduce layers.

Rung 2 of 4: light-to-medium fluid, given the oil-phase ingredients (Macadamia Ternifolia Seed Oil, Squalane, Caprylic/Capric Triglyceride) alongside its water phase — apply after any water-based toner/essence and before your moisturizer. This is an emulsion, not a pure water-based serum, so avoid layering a facial oil beneath it.

Retinol and Retinal are both small, lipophilic molecules that penetrate readily — unlike PDRN or peptides, this is one of the few actives in this catalog with genuine dermal penetration, which is part of why its irritation profile is real and its onboarding schedule matters.

Rest days are required: skin needs 48-72 hours between retinol applications while building tolerance, since the ingredient's renewal effect continues working well after application. Exceeding a safe frequency does NOT produce faster results — it produces barrier damage, redness, and a purge-like reaction that can look like the product "not working" when it is actually overworking.

Purging vs. reaction: PURGING occurs in your usual breakout areas, stays surface-level, and resolves within 4-6 weeks. A REACTION — stop immediately — occurs in new areas, involves burning, swelling, or hives, and worsens rather than improves over time.

Before starting this product, your routine MUST already include a consistent daily SPF habit and a basic gentle-cleanser-plus-moisturizer foundation. Without these, this product causes more harm than benefit.

Graduation ladder: if you are new to retinoids, Medicube's own Deep Vita A Retinol Serum (a lower, multi-form 0.1% HPR-led complex) is a gentler starting point in this same catalog before stepping up to this 1.9% formula.

Barrier index gate: if your skin stings on moisturizer, feels tight within 30 minutes of cleansing, or shows visible flaking, your barrier is below threshold — start with a plain Cica-forward barrier product (see below) before introducing a retinol this strong.

Fine lines and smile lines: Retinol accelerates keratinocyte turnover and stimulates collagen-related signalling; the brand cites an 11% smile-line improvement figure. Pore-area firmness and texture: brand-cited 2.8% pore-firmness and up to 14.7% pore-area texture improvement. Surface hydration: NMN, Niacinamide, and the probiotic ferment complex are the supporting cast, cited at 13.6% hydration improvement.

This product cannot remove deep static wrinkles in a single course of use, cannot substitute for filler/structural treatments for volume loss, and cannot compensate for inconsistent SPF use — retinoid benefits are actively undone by unprotected sun exposure.

Primary AM antioxidant pairing (never same routine as this PM retinol, by design — see Conflict Solver): Medicube Deep Vita C Capsule Serum 30ml. Alternatives: Deep Vita C Capsule Cream 55g, AGE-R Vita C Pro Ampoule 20ml, Deep Vita C Ampoule 2.0 30g — all confirmed in stock.

Sunscreen (mandatory next-morning close): primary Medicube Glow Collagen Sunscreen 50ml SPF50. Alternatives: Collagen Firming Sun Cream SPF50+ PA++++, PDRN Hydrating UV Serum.

Barrier-repair pairing for recovery nights: PDRN Pink Cica Soothing Toner 250ml or Exosome Cica Cream 50ml — both confirmed in stock.

Pilling risk: moderate if layered with a heavy silicone-forward primer the next morning; wait the full 2-5 minutes before moisturizer to reduce this on retinol nights.

This is a conflict-solver for ACTIVE ingredients. If you run multiple actives, use these rules to avoid irritation, deactivation, and barrier damage. One Active Lane per routine: run only one primary active lane per night.

× AHAs (Glycolic/Lactic/Mandelic): never the same night — use Skin Cycling (Night 1 AHA, Night 2 this serum, Nights 3-4 Recovery) or alternate nights entirely.

× BHA (Salicylic Acid): avoid the same night for most people — BHA on non-retinoid nights, or split AM BHA / PM this serum if you tolerate both.

× Benzoyl Peroxide: do not layer — BPO can oxidize/deactivate retinol and doubles irritation. Use AM BPO / PM this serum instead, or a wash-off BPO cleanser.

× L-Ascorbic Acid (pure Vitamin C): don't layer in the same routine — the classic AM Vitamin C / PM this serum split is the safer structure.

× Strong peel actives: never the same day — treat a chemical peel as its own lane with 48-72h recovery before resuming this serum.

Prescription conflict: if you are currently using prescription tretinoin, adapalene, or isotretinoin, consult your dermatologist before combining with this product — its 1.9% disclosed Retinol concentration is high enough that stacking with a prescription retinoid meaningfully raises irritation risk.

Scheduling template (AM/PM split, most common): AM — antioxidant lane, moisturizer, SPF. PM — this serum on retinoid nights, moisturizer. Close: do not layer retinoids with AHA/BHA in the same night; keep "one lane" per night.

MYTH: "A 'low-irritation' or 'encapsulated' retinol claim means you can skip the slow introduction." REALITY: Encapsulation can genuinely reduce surface irritation versus free retinol at the same %, but 1.9% is still a high concentration — the standard phased onboarding protocol below still applies regardless of the brand's marketing framing.

MYTH: "More retinol nights per week means faster results." REALITY: Retinoid renewal works on a cellular turnover timeline measured in weeks; exceeding a safe frequency produces barrier damage and redness, not faster collagen remodeling.

July-November sugar cane burning season increases PM2.5 in the air; this serum's Niacinamide and antioxidant-adjacent ingredients offer modest general pollution defense, but this is not a reason to increase retinol frequency — treat the two concerns separately.

*NMN and the probiotic complex's irritation-buffering claim are brand-marketed mechanisms without independent published data specific to this formula; treat the ingredient presence as confirmed and the mechanism claim as Marketing-Only.

Full INCI (recovered ~36 ingredients; brand/retailer copy references additional beta-glucan content in the tail not independently located by name): Water, Glycereth-26, Niacinamide, Glycerin, Caprylic/Capric Triglyceride, Macadamia Ternifolia Seed Oil, Butylene Glycol, Hydrogenated Lecithin, Retinol, [--- Estimated 1% Line ---] Brassica Campestris (Rapeseed) Sterols, 1,2-Hexanediol, Cholesterol, Polyglyceryl-10 Laurate, Phytosteryl/Behenyl/Octyldodecyl Lauroyl Glutamate, Aluminum/Magnesium Hydroxide Stearate, Pentaerythrityl Tetra-Di-T-Butyl Hydroxyhydrocinnamate, Potassium Cetyl Phosphate, Tris(Tetramethylhydroxypiperidinol) Citrate, Glyceryl Citrate/Lactate/Linoleate/Oleate, Elaeis Guineensis (Palm) Oil, Cetyl Ethylhexanoate, Hydroxyacetophenone, Ammonium Acryloyldimethyltaurate/VP Copolymer, Polyacrylate Crosspolymer-6, Aluminum Starch Octenylsuccinate, Retinal, Squalane, Polyquaternium-51, Tocopherol, Panthenol, Allantoin, Adenosine, Disodium EDTA, Bifida Ferment Lysate, Lactobacillus Ferment Lysate, Lactococcus Ferment Lysate, Dipropylene Glycol.

This ordered list is reconstructed from ingredient-database and retailer listings surfaced via web search (direct database fetch was blocked in this research pass). The 1.9% Retinol figure specifically is high-confidence, brand-stated and corroborated across 5+ independent retailer listings; the exact ordered position of every remaining ingredient is medium confidence.

Preservative system: 1,2-Hexanediol (glycol-type preservative booster), Disodium EDTA (chelator, not itself a preservative).

Fragrance status: Fragrance-Free — no Fragrance/Parfum entry found, confirmed across multiple independent sources. EU-26 allergen screen: none detected individually in the recovered INCI.

Alcohol disclosure: Alcohol-Free — no SD Alcohol/Alcohol Denat/Ethanol found; 1,2-Hexanediol is a glycol-type preservative booster, not a drying alcohol.

Prescription retinoid interaction: if you are currently using prescription tretinoin, adapalene, or isotretinoin, consult your dermatologist before combining with this product — this is the single most important interaction for this specific SKU, given its genuinely high 1.9% disclosed concentration.

Photosensitizing medications: if you take a photosensitizing medication (certain antibiotics, isotretinoin, some diuretics), the combination with a retinol this strong increases overall sun-sensitivity risk — check with your prescribing doctor.

Halal: *Self-assessed by Adilsons based on available INCI data. No overtly animal-derived or fermentation-alcohol ingredient was identified in the portion of the INCI recovered this round, but that list is incomplete (~36 of a longer full ingredient set), so this is a tentative, not confident, self-assessment. This is NOT a formal Halal certification. Muslims with stricter requirements should consult their own scholars.

Vegan: *Self-assessed by Adilsons based on available INCI data. No animal-derived ingredient was identified in the recovered portion of the INCI, but the list is incomplete, so this is presented as a tentative finding rather than a confident vegan claim. This is NOT a formal vegan certification.

Cruelty-Free: *Brand-stated policy, not independently certified by Leaping Bunny, PETA, or an equivalent third-party audit. Medicube also sells a separate China-market line through mainland China retail, where post-market animal testing may be legally required; cross-border e-commerce sales may be exempt.

Microplastic-Free: Yes — no solid-particle microplastic ingredient identified in the recovered INCI; Polyacrylate Crosspolymer-6 and the Ammonium Acryloyldimethyltaurate/VP Copolymer are water-soluble texturizing polymers, not insoluble microplastic particles.

MFDS Classification: Not confirmed — presence of Niacinamide and Adenosine makes a functional-cosmetic registration plausible but unverified.

Clinical evidence: brand-cited in-house data reports 11% smile-line improvement, 2.8% pore-firmness increase, 13.6% surface hydration increase, 5.8% skin-density improvement, 14.7% pore-area texture improvement, and 11.8% visible pore smoothing after two weeks. *The institution behind this study is cited inconsistently across sources as either a "Global Dermatological Research Institute" or a "Global Skin Science Institute" — neither could be independently verified as a real, checkable research body, and no sample size or peer-reviewed methodology was found. Treated as Marketing-Only evidence.

Evidence Confidence: Strong for Retinol as an ingredient class (independently well-studied); Marketing-Only* for this product's specific percentage figures and for the "irritation-free" positioning at this concentration.

Fungal Acne Safety: FA-Conditional. Polyglyceryl-10 Laurate (a confirmed brand-wide FA-conditional pattern) and Cetyl Ethylhexanoate (a fatty-acid ester some trackers flag conditionally) are both present in the recovered INCI.

Assessment: Medium. The multi-emollient oil phase (Macadamia oil, Squalane, Palm Oil, several ester-type texturizers) can pill if layered under a heavy moisturizer before fully absorbing. Mitigation: apply to fully dry skin, wait the full recommended time, and pat the next layer in rather than rubbing.

Fresh retinol serums are typically a pale, off-white to faint-yellow emulsion; retinoids oxidize on exposure to air, heat, and light, turning noticeably darker/browner and losing potency — an oxidized retinol product can also generate free radicals rather than fighting them, so discard if the color shifts meaningfully from what it looked like when new.

Storage: keep away from direct bathroom heat and humidity, and store the cap tightly closed between uses to limit air exposure — retinol is one of the more storage-sensitive actives in a typical routine.

Patch test on the inner forearm for 24 hours, then behind the ear for 24 hours, before beginning facial use — this matters more than usual given the 1.9% concentration.

If an adverse reaction occurs: stop all actives, and for 72 hours use only a gentle cleanser and plain moisturizer with mineral SPF — no acids, retinoids, Vitamin C, exfoliants, or essential oils. After 72 hours, reintroduce one product per 14 days.

Emergency stop signals: hives, swelling, blistering, persistent burning, or breathing difficulty — seek emergency care immediately.

Pregnancy-safe alternatives: Niacinamide- or Azelaic Acid-based serums are the standard pregnancy-safe substitutes for a retinol's tone/texture benefits. In this catalog: Medicube Azelaic Acid 16 BB Calming Serum 30ml (confirmed in stock, 2 units) is a genuinely different, non-retinoid active lane suitable during pregnancy with a doctor's clearance for any new active.

1. Starting at nightly use because a brand claim says "irritation-free" — start at 2x/week regardless of marketing language. 2. Applying to damp skin, which increases retinol penetration and sting risk. 3. Skipping SPF the morning after use. 4. Layering with a separate AHA/BHA or Vitamin C product the same night. 5. Using while pregnant or nursing without checking the ingredient list first.

Overuse threshold: more than 4x per week at this concentration does not accelerate collagen remodeling — it raises barrier-damage risk substantially, since retinization is a cellular-timeline process, not a dose-response one.

At a pea-sized amount (~2-3 drops) per use, 2-4x per week, a 30ml bottle provides roughly 10-15 weeks of use at the recommended frequency. Using it nightly instead would roughly double the depletion rate while also raising irritation risk — the recommended lower frequency is a safety choice as much as an economy one.

Reorder roughly two weeks before you expect to run out, to allow for shipping time.

This serum's role is the PM anchor active, sitting in the light-emulsion viscosity tier. PM: double cleanse → toner (optional) → fully dry skin → this serum (retinoid nights only) → moisturizer. AM: antioxidant serum (optional) → moisturizer → mandatory SPF50+.

If your barrier currently stings or flakes: do not start this product yet — repair with a plain moisturizer and Cica-forward toner for 1-2 weeks first. If you are pregnant or nursing: do not use this product — see the pregnancy-safe alternative above. If you are already on a prescription retinoid: do not add this product without your dermatologist's guidance, since 1.9% is a genuinely high additive dose.

Suggested stock-true pairing set: this serum + PDRN Hydrating Gel Cleanser + PDRN Pink Hyaluronic Moisturizing Cream + Glow Collagen Sunscreen SPF50 — all confirmed in stock.

The recommendations above are based on formulation synergy with Retinol NMN Boosting Serum, 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.

If you are new to retinoids, pregnant/nursing-adjacent in your planning, or simply want a gentler entry point, Medicube's own Deep Vita A Retinol Serum 30ml (a lower, multi-form 0.1% Hydroxypinacolone Retinoate-led complex, confirmed in stock) is the gentler in-catalog alternative — note it still contains retinoids and is still not pregnancy-safe, just at a lower disclosed strength. For a genuinely non-retinoid active lane: primary Azelaic Acid 16 BB Calming Serum 30ml (confirmed in stock). Alternative: TXA Niacinamide Capsule Cream 55g (confirmed in stock) for a pure brightening/tone-support lane with zero retinoid content.

Choose Retinol NMN Boosting Serum over the Deep Vita A Retinol Serum if you need higher active strength: 1.9% Retinol is a disclosed, meaningfully higher concentration than Deep Vita A's disclosed 0.1% HPR figure, for someone who already has established retinoid tolerance.

If you have used a lower-strength retinoid (0.1-0.3%) consistently for 8+ weeks without irritation, then stepping up to this 1.9% formula is a reasonable graduation. If you are new to retinoids entirely, then start with Deep Vita A Retinol Serum or a bakuchiol/niacinamide-only product instead.

Don't upgrade yet if your barrier is currently compromised, you can't commit to consistent daily SPF, you are already using a same-strength or stronger prescription retinoid, or you are new to actives generally — 1.9% is a high-strength starting point by any standard.

A realistic progression within this catalog: start with a niacinamide-only or azelaic-acid product to confirm baseline tolerance → graduate to Medicube's Deep Vita A Retinol Serum (0.1% HPR-led) for 8-12 weeks → graduate to this Retinol NMN Boosting Serum (1.9% Retinol) once tolerance is established. Skipping the middle step is possible but raises the odds of an uncomfortable adjustment period.

This product's PRIMARY function is: high-strength retinoid renewal for fine lines, pore-area firmness, and texture. You do NOT need this if you already own an unopened, unexpired retinol product at a comparable or higher concentration — finish that first.

Check your current routine for any other retinoid (prescription or OTC) before buying this one; running two retinoid products at once is No Benefit (same mechanism, same pathway) and meaningfully raises irritation risk rather than adding a new benefit.

Medicube positions itself as a "medical beauty" brand pairing at-home devices with companion topical actives. This serum represents the brand's push into higher-concentration, clinically-postured actives alongside its more identity-driven PDRN storytelling — a genuinely different formulation philosophy (precision-dosed single active) from the brand's usual multi-ingredient, story-led product pattern.

Aggregated review sources (Amazon listing, a dedicated first-person Lemon8 review, and multiple K-beauty retailer summaries) lean positive: several reviewers, including at least one self-described retinol beginner, reported starting at 2 nights/week and building up without significant purging or irritation, which is a genuinely encouraging signal at this concentration. Reviewers praised effects on smile lines, pore firmness, and surface hydration, broadly consistent with (though not proof of) the brand's clinical claims. No dedicated Reddit thread or counterfeit-specific complaint was found for this exact SKU in this research pass. No individually-attributable, dated review quote is reproduced here — this is a paraphrase of aggregate themes only, consistent with this skill's honesty rule.

How much retinol does this actually contain? A brand-stated 1.9% Retinol, plus a second undisclosed-dose retinoid, Retinal, in the same formula — a genuinely high, disclosed concentration.

Can I use this if I'm pregnant? No — do not use this product during pregnancy or while nursing.

Is it really "irritation-free" like the marketing says? Treat that as a brand claim, not a guarantee — the standard slow introduction (2x/week to start) still applies regardless.

Can beginners use this? Not recommended as a first retinoid — Medicube's own Deep Vita A Retinol Serum (0.1% HPR) is a gentler starting point in this catalog.

Do I need sunscreen the next morning? Yes, always — retinol increases photosensitivity for roughly 24 hours after use.

Retinol

A Vitamin A derivative that speeds cell turnover and supports collagen; contraindicated in pregnancy.

Retinal

Retinaldehyde, a more potent Vitamin A form that converts to retinoic acid in fewer steps than retinol.

Retinization

The temporary adjustment period (flaking, mild sensitivity) skin goes through when starting a retinoid.

NMN

Nicotinamide Mononucleotide, a cellular-energy-adjacent ingredient with a newer, less established topical evidence base than retinol.

Skin Cycling

A 4-night rotation (exfoliation, retinoid, recovery, recovery) that limits over-exfoliation and barrier damage.

TEWL

Transepidermal water loss — moisture escaping through the skin's outer barrier, which retinoids can temporarily increase.

Phased Onboarding

A gradual introduction schedule (starting at low frequency, building up) used for strong actives like retinol.

Best for: an established retinoid user, not pregnant or nursing and over 16, who wants a genuinely high, disclosed 1.9% concentration and is willing to follow a proper phased introduction rather than trusting the "irritation-free" marketing claim alone.

Key benefits: a rare, brand-disclosed high retinol concentration; probiotic-buffered formulation story; fragrance-free; currently in stock at Adilsons.

Keep in mind: a second undisclosed-dose retinoid (Retinal) adds to the total retinoid load beyond the 1.9% headline number; not suitable during pregnancy/nursing or under 16; the brand's clinical-claim institution name is inconsistent across sources, so treat the specific percentage figures as marketing context, not independent proof.
