Medicube (1EA) EGF NAD FIRMNG GEL MASK

Values: 100% Genuine (Adilsons policy) · Fragrance-Free* · No safety-gate ingredients detected

*Based on the ~49 of a reported 55 ingredients we could reconstruct from brand/retailer sources; no explicit Fragrance/Parfum entry surfaced, but the list is incomplete. Patch test advised.

*One retailer (Stylevana) lists 23g per sheet for the 4EA multipack; we could not resolve this to a single authoritative figure this round.

Pros: molds tightly to the face for side-sleepers, real (though undisclosed-concentration) EGF and NAD actives rather than pure marketing filler, no reported irritation in the reviews we found, non-comedogenic per brand claim.

Caveats: low current stock at Adilsons (5 units), NAD+ concentration rests on a single uncorroborated retailer figure, and the brand's headline "6 facial areas" clinical study was found attributed to the companion serum, not this mask specifically.

Classification: GREEN (generally safe for most ages) with a caveat — this is not a harmful formula for younger skin, but it is also not designed for it. Peptide/growth-factor signaling and NAD+ target processes tied to age-related collagen and elastin decline that prepubescent and teenage skin has not yet begun to experience.

There is no youth-targeted packaging or marketing on this SKU, so the usual "packaging trap" concern does not apply here. For a younger user genuinely interested in a treatment mask, a plain hydrating sheet mask without firming-actives marketing is a more age-appropriate starting point — Adilsons carries several basic hydrating masks that fit that role better than a firming-specific formula.

Compatibility checklist: bedside-compatible (yes — no sink needed if applying pre-cleansed skin); requires rinsing (no, optional only); requires precise dosage (no — one sheet is the whole dose); applicable with unwashed hands (better with clean hands, but low-effort); requires wait time (yes, passive — you can go to sleep during it); can it be a single-product routine (yes, in a pinch, on an already-cleansed face).

Minimum viable routine position: this qualifies well for a low-energy night — press it on and go to sleep, with zero additional steps required.

Sensory aversion check: the initial 15-minute tacky phase before the gel sets may bother anyone who wants to lie down immediately; if that's a dealbreaker on a given night, a lighter leave-on serum is the more forgiving choice.

Step 1 (When): PM — after cleansing and your usual serum, before you'd normally seal with moisturizer.

Step 2 (How much): One full sheet unfolded and pressed onto clean, dry skin — this is a single-use, single-application sachet.

Step 3 (How): Smooth from center outward, press to remove air bubbles, leave 15-20 minutes for a quick treatment or overnight for a deeper one; do not rub.

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 treatment. If you wore it overnight, your AM routine starts with removing any remaining film, gently patting in leftover essence, then continuing as normal: (1) rinse cleanse if skin feels tacky, (2) toner, (3) vitamin C or other AM antioxidant serum, (4) moisturizer, (5) SPF50+ PA++++, non-negotiable.

Mauritius humidity note: because the mask's essence phase leans on humectants (Glycerin, Betaine, Glucomannan), any residue left on skin in the morning still draws moisture from the humid morning air — pat it in rather than washing it off immediately if your skin feels comfortable.

1. Double cleanse (oil then water cleanser) if wearing SPF/makeup. 2. Toner. 3. Treatment serum (e.g. a collagen or peptide serum). 4. Medicube EGF NAD Firming Gel Mask — press on, leave 15-20 minutes or overnight. 5. If removing after 15-20 minutes, pat in remaining essence and follow with your usual moisturizer; if wearing overnight, skip moisturizer that night since the mask itself is the final leave-on layer.

Skin cycling note: this is not an exfoliant or retinoid, so it doesn't occupy a "night off" slot — use it 2-3x per week on any night, independent of an acid/retinoid schedule.

Technique: Press, don't rub — friction can shift the hydrogel out of place and reduce even contact. Required skin state: clean and dry (the mask needs to adhere to skin, not a damp toner layer). Wait time: 15-20 minutes minimum; up to overnight for a deeper treatment, with the sheet visibly turning from opaque to transparent as it's absorbed.

Hands vs. tools: use clean, dry hands to smooth the sheet on and press out air pockets — no cotton pad is involved in this step.

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 rules: viscosity ladder thinnest to thickest, water-phase before oil-phase, treatments before seals. Wait-time defaults: watery layers 10-20s, serum layers 30-60s, before sunscreen 10-15 min if going outdoors. Amount defaults: toner 5-8 drops, serum 2-3 drops or 1 pump, eye product half a rice-grain per eye, gel moisturizer 1-1.5 peas, cream 1-2 peas, sunscreen 2-finger rule for face plus 1 finger for neck. Hydrators sit best on slightly damp skin; retinoids on fully dry skin. If a routine pills, stings, or feels heavy, reduce layers, not increase.

AM Maximum Stack: 1. Rinse/gentle cleanse (optional) 2. pH-prep toner (optional) 3. Hydrating toner layers (1-3, optional) 4. Essence (optional) 5. Mist (optional) 6. Booster/soothing serum (optional) 7. Antioxidant lane — pick ONE (Vitamin C or a gentler antioxidant) 8. Pigment-support lane (optional) 9. Hydration serum lane (optional) 10. Oil-control lane (optional) 11. Peptide/growth-factor/repair lane (optional — this product's active category, though this specific product is a PM treatment, not part of the daily AM stack) 12. Eye serum/cream 13. Moisturizer 14. Optional sealing layer (AC/dry days) 15. Sunscreen SPF50+ PA++++ (non-negotiable) 16. Lip SPF. In AM, prioritize comfort and SPF adherence over stacking — in high humidity, fewer layers often perform better.

PM Maximum Stack: 1. Micellar pre-cleanse (optional) 2. Oil cleanser/balm (if SPF/makeup) 3. Water cleanser 4. pH-prep toner (optional) 5. Hydrating toner layers (optional) 6. Essence (optional) 7. Soothing/barrier serum (optional) 8. [Anchor slot — this mask goes here 2-3x/week] 9. Targeted serum (optional, non-conflicting only) 10. Moisturizer (skip if wearing the mask overnight as your final layer) 11. Sleeping mask (this product, on treatment nights) 12. Occlusive seal (optional, avoid if clog-prone) 13. Spot treatment (as needed) 14. Lip sleeping mask (optional). Do not layer retinoids with AHA/BHA in the same night; keep "one lane" per night.

This sits at the thickest end of the leave-on ladder — a hydrogel sheet, applied as the final treatment layer after any thinner serums and before (or instead of) your usual moisturizer.

Layering rule: thinnest to thickest, water-phase before oil-phase — apply this mask after toners/serums have fully absorbed, not before.

Molecular-weight note: the EGF-mimetic peptide in this formula (sh-Oligopeptide-1) is a recombinant protein analog, meaningfully larger than the commonly-cited "500 Dalton" penetration threshold for small molecules. It is understood to act primarily at the skin surface and upper epidermis — signaling keratinocytes rather than reaching deep dermal collagen directly. This does not make it ineffective, but "deep penetration" is not the correct mechanism to expect here.

Phase compatibility: aqueous/hydrogel — compatible with water-based serums and toners underneath; avoid applying facial oils immediately before, since oil can prevent the hydrogel from adhering evenly.

Rest days aren't strictly required biologically since this product carries no exfoliating acid or retinoid, but 2-3x/week keeps it a genuine treatment rather than a routine crutch, and gives you a clear before/after read on results.

Overuse warning: using it nightly does not accelerate firming results — it just uses up your (currently limited-stock) supply faster with no added benefit, since the mechanism is signaling-based, not dose-stacking.

Before starting this product, your routine should already include a basic cleanser and a daily moisturizer. It is not a foundational step and works best layered onto an already-functioning routine, not as a fix for a missing one.

Loss of firmness/elasticity: the peptide complex (Acetyl Hexapeptide-8, Acetyl Tetrapeptide-2/3/5/9, Copper Tripeptide-1, Palmitoyl Pentapeptide-4/Tripeptide-1) is designed to signal fibroblasts toward collagen/elastin support, alongside the EGF-mimetic sh-Oligopeptide-1 which supports epidermal turnover and repair signaling.

Dehydration-related dullness: the glycerin/betaine/glucomannan humectant base plumps the surface, which reads visually as smoother, more "lit from within" skin the next morning.

Secondary benefit: Niacinamide at a brand-stated 2% offers a modest barrier-support and tone-evening assist alongside the firming story.

What this product cannot do: it cannot physically lift sagging tissue, cannot replace injectable or device-based skin tightening, and cannot reverse structural volume loss — the "firming" here is a surface-and-signaling effect on texture and short-term elasticity perception, not a mechanical lift.

Every pairing below was checked live against the Adilsons catalog for real stock, not just active status. We do not currently carry the companion EGF NAD Firming Serum as a same-line "duo" pairing — that specific SKU is under sourcing review.

Pre-mask serum — primary: Medicube Triple Collagen Serum 4.0 55ml — apply before the mask on treatment nights so the mask seals a fresh collagen-support layer underneath. PM.

Alternatives: Medicube Collagen Glow Booster Serum 15ml, Medicube PDRN Pink Collagen Bubble Serum 95ml (contains Retinol — PM only, see safety note below), Medicube PDRN Collagen Glow Jelly Serum 30ml (currently very low stock).

Cleanser to prep skin — primary: Medicube PDRN Hydrating Gel Cleanser 200ml — a gentle amino-acid/betaine base that won't strip skin before a hydrating treatment. AM/PM.

Alternatives: Medicube Zero Foam Cleanser 120g, Medicube PDRN Pink Niacinamide Whip Cleanser 120g, Medicube Zero Pore Clearing Capsule Cleansing Foam 120g.

Morning SPF (mandatory follow-through) — primary: Medicube Collagen Firming Sun Cream 50+SPF PA++++ 50ml — matches the firming positioning for AM. AM only.

Alternatives: Medicube Glow Collagen Sunscreen 50ml SPF 50, Medicube PDRN Hydrating UV Serum 50ml, Medicube Triple Collagen Cream 4.0 50ml (a cream, not a dedicated sunscreen — check its own SPF claim before relying on it for daily UV protection).

Pilling note: this mask is a self-contained hydrogel layer, not a liquid product layered under others, so pilling risk with itself is minimal; the main pilling risk is applying it over a not-yet-absorbed heavy serum.

Permeability: Film-Forming (uncertain) while worn — the hydrogel sheet itself is a physical film sitting on the skin surface, though it is designed to gradually absorb and thin out over its wear time.

While the sheet is on, it likely interferes with water reaching the skin directly during ablution. Once removed and any residual essence patted in, the skin surface should return to a normal, water-permeable state within a short time.

Removal method: remove the sheet fully before performing wudu if you plan to pray during or shortly after your treatment window; a quick rinse of the treated area afterward is sufficient.

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: "EGF in skincare works like injected growth factor and will visibly lift my face overnight." REALITY: Topical EGF-mimetic peptides are large molecules that primarily signal at the skin surface; they support epidermal turnover and texture over weeks, not an instant lifting effect.

MYTH: "NAD+ in a mask recharges cellular energy the same way an IV or supplement does." REALITY: Topical NAD+ has a plausible but still-emerging evidence base for skin-specific effects, and this SKU's own concentration (a single uncorroborated ~10.1ppm retailer figure) is a trace amount — treat the NAD+ story as part of the formula, not the sole driver of results.

MYTH: "A mask that turns fully clear means all the product has 'worked.'" REALITY: The transparency is the hydrogel's water phase being absorbed — it's a sign the essence has been delivered, not a guarantee of a specific biological outcome.

Hard water note: if your tap water leaves a slightly tight, filmy feel after cleansing, use a pH-balancing toner before this mask — a hard-water residue under the hydrogel can slightly reduce even adhesion.

*Niacinamide's 2% is a front-of-pack brand claim, not an independently audited assay. EGF, NAD+, and the peptide complex concentrations are not publicly disclosed by the brand; the NAD+ figure specifically comes from one uncorroborated retailer listing. Their inclusion is scientifically plausible but their real-world efficacy at undisclosed doses cannot be independently verified.

Full INCI (reconstructed from WebSearch aggregation of retailer/ingredient-database listings; brand states 55 total ingredients, we could confirm 49 — full ingredient list not fully publicly disclosed at the time of writing): Water, Glycerin, Methylpropanediol, Acrylates/Ethylhexyl Acrylate Copolymer, Niacinamide, Chondrus Crispus (Irish Moss) Powder, [--- Estimated 1% Line ---] 1,2-Hexanediol, Ceratonia Siliqua (Carob) Gum, Theobroma Cacao (Cocoa) Extract, Collagen, Betaine, Hydroxyacetophenone, Glucomannan, Allantoin, Cellulose Gum, Cyamopsis Tetragonoloba (Guar) Gum, Potassium Chloride, Laureth-21, Dextrin, Adenosine, Ethylhexylglycerin, Nicotinamide Adenine Dinucleotide (NAD+), Ectoin, Maltodextrin, Butylene Glycol, Lecithin, Tocopherol, Sodium Phosphate, sh-Oligopeptide-1 (EGF), Dipotassium Glycyrrhizate, Tromethamine, Acetyl Hexapeptide-8, Ascorbic Acid Polypeptide, Quercetin, sh-Oligopeptide-2, sh-Polypeptide-1, sh-Polypeptide-10, sh-Polypeptide-11, sh-Polypeptide-3, sh-Polypeptide-59, sh-Polypeptide-9, Acetyl Octapeptide-3, Acetyl Tetrapeptide-2, Acetyl Tetrapeptide-3, Acetyl Tetrapeptide-5, Acetyl Tetrapeptide-9, Carnosine, Copper Tripeptide-1, Nonapeptide-1, Palmitoyl Pentapeptide-4, Palmitoyl Tripeptide-1 (plus an estimated ~6 additional trailing ingredients not captured in this research pass).

*Fairy dusting note: NAD+ and the individual peptide/protein actives sit at undisclosed concentrations and appear late in the INCI order relative to a 55-ingredient list — consistent with this brand's documented pattern (across multiple other SKUs) of headline actives appearing at trace, marketing-oriented doses. This is a plausibility flag, not proof of an ineffective dose.

Delivery system: a hydrogel sheet that transitions from opaque to transparent as the essence phase absorbs. Brand marketing describes an "ultra-fine nano liposome NAD+" delivery claim; no published particle-size study was found to independently verify this.

Preservative system: 1,2-Hexanediol and Ethylhexylglycerin — a paraben-free, glycol-and-glyceryl-ether preservative-booster pairing common in modern K-beauty formulas.

Fragrance status: Fragrance-Free, based on the reconstructed INCI — no Fragrance/Parfum entry surfaced. *This is based on an incomplete reconstruction (49 of 55 reported ingredients); if the remaining ~6 include a fragrance entry, this assessment would need revision.

Scent: No detectable scent reported in reviews found.

EU 26 allergen screen: None detected in the declared INCI captured this run.

Alcohol disclosure: Alcohol-Free — no Alcohol Denat. or drying alcohol identified.

Halal: No formal halal certification found for Medicube as a brand. *Self-assessed by Adilsons based on available INCI data: this specific SKU contains Collagen, an animal-derived ingredient of undisclosed species/sourcing — we could not confirm a halal-permissible source, so this product should not be assumed halal-compliant without further verification. Muslims with halal requirements should consult their own scholars or the brand directly before use.

Vegan: Not vegan. This formula contains Collagen, an animal-derived ingredient, at an undisclosed position in the INCI. Do not treat this as a vegan-friendly product.

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

Microplastic status: No — contains Acrylates/Ethylhexyl Acrylate Copolymer, a synthetic film-forming polymer that is not readily biodegradable.

MFDS classification: Not confirmed as a Functional Cosmetic for this SKU — treat as a General Cosmetic (no additional government efficacy testing requirement applies).

Clinical evidence: Brand/retailer marketing cites a "clinically tested to improve elasticity across 6 facial areas" claim for the mask generally, and a separate, more detailed 2-week study (forehead lines -6.482%, skin volume +17.471%, uneven tone -12.639%, attributed to "Global Institute of Dermatological Sciences," Dec 2025-Feb 2026) — but this detailed study was found attributed to the companion EGF NAD Firming Serum, not independently confirmed as applying to this mask SKU. *Evidence confidence: Marketing-Only for both claims — no independently published, peer-reviewed study was found for either the mask or the named institution.

Non-comedogenic/irritation claim: *Brand claims "non-comedogenic and clinically tested for skin irritation" but no publicly available study data, sample size, or testing protocol has been disclosed.

*See the At-a-Glance section for the 23g/28g cross-retailer discrepancy noted this run.

Fungal Acne Safety: Likely FA-Safe. None of this brand's previously documented FA-conditional ingredients (Cetearyl/Sorbitan Olivate, Polyglyceryl-10 esters, Ethylhexyl Palmitate, Isopropyl Myristate) appear in the reconstructed INCI. *This is a medium-confidence assessment based on an incomplete ingredient list (49 of 55 reported ingredients) — highly FA-sensitive users should still patch test.

Assessment: Low. As a self-contained sheet rather than a liquid layered under other products, this mask itself doesn't pill — the only pilling risk comes from applying it over a heavy, not-yet-absorbed serum underneath, which can create uneven adhesion rather than classic ball-up pilling.

Mitigation: let any prior serum absorb for a full 60 seconds before pressing the mask on; apply to fully dry (not damp) skin for the most even contact.

Color baseline: Fresh sheets are translucent-white/clear gel. Any yellowing, browning, or a sour/off smell before use signals spoilage — discard rather than apply.

Storage: Keep the sealed sachet away from direct heat and humidity spikes — a bathroom cabinet away from the shower, not a windowsill, is ideal in Mauritius's climate.

Spoilage signs: torn/leaking sachet seal, discoloration, separation of the gel, or an unusual smell. When in doubt, discard.

Patch test: apply a small piece of the sheet to your inner forearm for 24 hours, then behind the ear for 24 hours, before your first full-face application.

72-hour barrier reset: if you experience an adverse reaction, stop all actives. For 72 hours, use only a gentle cleanser, plain moisturizer, and 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.

1. Using it nightly, expecting faster results — the signaling mechanism doesn't dose-stack that way. 2. Applying over a heavy, unabsorbed serum, causing uneven adhesion. 3. Rubbing rather than pressing the sheet on, which can shift it out of place. 4. Skipping SPF the next morning because "the mask did the anti-aging work" — firming actives do not replace daily sun protection. 5. Treating the single 1EA sachet as a multi-use product — it's designed for one full-face application only.

Overuse threshold: more than 3-4x/week provides no added benefit and simply depletes your (currently limited) supply faster.

This 1EA unit is a single, one-time full-face application — there is no "per-use math" beyond that single sheet. If you plan to use a mask like this 2-3x per week as part of an ongoing routine, you'll want to reorder (or consider the multi-sheet packs some retailers carry internationally) rather than treat this single sachet as a recurring supply.

Reorder timing: since this is a single-use item, reorder whenever you're ready for your next treatment session — there's no depletion curve to track.

This product does the firming/hydrating "treatment" step in a routine that still needs its own cleanser, daily moisturizer, and SPF around it — it is not a full routine by itself.

PM: 1. Cleanse. 2. Toner. 3. Treatment serum (see pairing above). 4. EGF NAD Firming Gel Mask — press on, 15-20 min or overnight. 5. If removed after 15-20 min, follow with your usual moisturizer.

AM (the following day, if worn overnight): 1. Remove any leftover film, pat in remaining essence. 2. Toner. 3. Antioxidant serum. 4. Moisturizer. 5. SPF50+ PA++++.

If your skin is barrier-compromised right now: hold off on this mask until skin feels calm for at least a few days — a signaling-peptide treatment isn't the priority when the barrier itself needs repair first.

If you're in AC all day and skin feels tight by evening: this mask's humectant load is a genuinely good fit for that state — plan your treatment nights for the days you've been in AC the most.

If you already use a retinol or acid-exfoliant at night: use this mask on a non-active night, since it works best as its own dedicated treatment slot rather than stacked on top of an active night.

Stock-true bundle: PDRN Hydrating Gel Cleanser + Triple Collagen Serum 4.0 + this mask + Collagen Firming Sun Cream gives a coherent firming-themed AM-to-PM routine using only currently-in-stock Medicube SKUs.

After purchasing, you will receive our skincare education email series covering this product in depth.

The recommendations above are based on formulation synergy with this mask, 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 want the same active-story (NAD+-forward, firming-positioned) in a different format, Numbuzin No.9 NAD Bio Lifting Essence 50ml is a real-dose Niacinamide leave-on serum-essence hybrid from a different brand that leans on the same NAD+ marketing story — a genuinely different texture (pump-bottle essence vs. sheet mask) and daily-use frequency rather than a 2-3x/week treatment.

If you'd prefer a different Medicube gel-mask format for a different concern, Medicube PDRN Pink Collagen Gel Mask targets the same firming/hydration space via salmon-derived PDRN instead of EGF/NAD, and Medicube Kojic Acid Turmeric Brightening Gel Mask shifts the focus to tone/brightening rather than firming.

Choose the EGF NAD Firming Gel Mask over the PDRN Pink Collagen Gel Mask if you specifically want to try the EGF-peptide-plus-NAD+ signaling story rather than the salmon-derived PDRN story: they target a similar end goal (firmer-feeling, more elastic-looking skin) through genuinely different active pathways.

If you match this trigger, upgrade to this mask: you've already used PDRN-based Medicube products and want to try a different active mechanism rather than more of the same one.

Don't upgrade if: you're new to Medicube's mask formats entirely — the PDRN Pink Collagen Gel Mask has a longer track record in this catalog and higher current stock, making it the steadier starting point.

If you match the trigger above, this mask is worth choosing. If not, the PDRN alternative is a perfectly sufficient starting point. Consistency in a 2-3x/week habit beats switching between formats.

This product's PRIMARY function is: overnight firming/hydration treatment via peptide and humectant signaling. You do NOT need this if you already own an open, unfinished firming sheet mask or sleeping pack (e.g. a PDRN Pink Collagen Gel Mask or Collagen Milk Toning Wrapping Mask) doing the same treatment-night job. Finish your current product before purchasing.

Since this is a single-use sachet with no PAO countdown once opened (it's used in one sitting), there's no "expiring half-used" waste risk the way there is with a jar or bottle — but stacking multiple unused treatment masks in a drawer is still worth checking before buying more.

Stacking assessment: Marginal Benefit if you already own a PDRN- or collagen-based firming mask (overlapping goal, different pathway); Significant Benefit if your current routine has no dedicated firming-treatment step at all.

This product is sourced through authorized Korean distributors — 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 verification tips: check that the sachet seal is fully intact with no tears; genuine Medicube packaging generally carries a QR-verification code and a legible batch stamp — if either looks smudged, misprinted, or absent, treat that as a red flag and refer to the Authenticity page above.

Medicube is the flagship skincare/beauty-device brand of APR Corporation (APR Co., Ltd., Korea Exchange ticker KRX:278470), founded in Seoul in 2014 by Byunghoon (Victor) Kim, with APR going public on the KRX in 2024. Medicube itself launched in 2016 and is headquartered in Seoul.

The brand positions itself as "medical beauty" / dermatology-adjacent skincare, historically built around PDRN (salmon-derived Polydeoxyribonucleotide) as its signature hero ingredient across the PDRN Pink Collagen line, alongside at-home devices (the AGE-R microcurrent/RF line) and a wide portfolio of parallel brightening actives. This EGF NAD Firming Gel Mask represents a newer sub-line for the brand, moving beyond PDRN into an EGF-peptide-plus-NAD+ story, sold alongside a companion serum internationally.

Whether Medicube's topical cosmetic formulas are manufactured in-house or via third-party Korean contract manufacturers has not been independently confirmed — this is separate from the brand's confirmed in-house device R&D for its AGE-R line.

We did not find a dedicated Reddit thread (r/AsianBeauty, r/SkincareAddiction) discussing this exact SKU at the time of writing — community reviews for this specific product were limited to Amazon listing pages, a Facebook review write-up, and short-form video reviews, which we treat as lower-confidence sources than a corroborated Reddit or forum thread.

Recurring praise across what we found: the hydrogel sheet molds closely to facial contours and stays in place overnight, including for side sleepers, without sliding off; skin is described as noticeably plumper and more hydrated the following morning; no irritation or breakouts were reported in the sources we reviewed.

Recurring caveat: the sheet is naturally sticky/tacky for roughly the first 15 minutes as it sets, which some reviewers found uncomfortable if they went straight to bed rather than waiting for it to feel less tacky first.

Sustainability: the sachet is a mixed-material laminate typical of sheet mask packaging, which is generally not recyclable through standard household recycling in Mauritius — dispose of it as general waste unless a dedicated cosmetics take-back program is available to you.

Can I leave this mask on overnight? Yes — the brand's own instructions support either a 15-20 minute quick treatment or an overnight wear, with the sheet gradually turning transparent as it's absorbed.

Do I need to rinse it off? Not necessarily — pat any remaining essence into your skin rather than rinsing, unless your skin feels sticky and you'd rather cleanse it off.

Is this the same as the EGF NAD Firming Serum? No — they're a companion "duo" sharing the same active story, but this is the sheet-mask format; the serum is a separate leave-on product not currently carried at Adilsons.

Will this replace my moisturizer? On the nights you wear it overnight, yes, it can act as your final leave-on layer; on nights you remove it after 15-20 minutes, follow with your usual moisturizer.

Is it safe to use if I'm pregnant? Based on the ingredients we could verify (no retinoids, acids, hydroquinone, or chemical UV filters), we found no ingredient on our pregnancy-caution list — but always confirm with your own doctor given the incomplete ingredient reconstruction for this specific SKU.

EGF (Epidermal Growth Factor)

A signaling protein that in this product is a biomimetic/recombinant peptide analog (sh-Oligopeptide-1), designed to mimic the skin-signaling behavior of natural EGF.

NAD+ (Nicotinamide Adenine Dinucleotide)

A coenzyme involved in cellular energy metabolism; its topical skincare benefits are an emerging, still-developing area of evidence.

sh-Oligopeptide / sh-Polypeptide

"sh" denotes a synthetic/recombinant human-identical protein sequence produced via fermentation, not an animal- or human-tissue-derived ingredient.

Hydrogel mask

A thick, water-based gel sheet that adheres closely to skin and gradually releases its essence as it's absorbed.

Fairy dusting

When a marketed "hero" ingredient is included at such a low concentration that it's unlikely to have a meaningful clinical effect.

1% line

The estimated point in an ingredient list below which ingredients are typically present at under 1% concentration, based on standard descending-order INCI convention.

PAO (Period After Opening)

The number of months a product remains safe/effective to use after first opening — not typically applicable to single-use sachets like this one.

Fungal Acne (FA) Safe

A formula that avoids ingredients known to feed Malassezia yeast, which can trigger fungal-acne-prone skin.

Source of Truth: This is a quick snapshot. If anything differs, the policy pages are final.

Store Policies: For the most up-to-date information, please review our Shipping Policy and Refund Policy.

Best for: anyone already comfortable with Medicube's firming-treatment format who wants to try a new EGF-peptide-plus-NAD+ active combination as a 2-3x/week overnight treatment, rather than a daily hydrator.

Key benefits: a genuinely broad peptide/growth-factor complex beyond just PDRN, a comfortable and well-reviewed hydrogel-sheet wear experience, brand-stated 2% Niacinamide for a real secondary benefit, and no safety-gate ingredients (fragrance-free, retinoid-free, acid-free) in the ingredients we could verify.

Keep in mind: individual active concentrations beyond Niacinamide are undisclosed, the brand's strongest clinical figures were found tied to the companion serum rather than this mask, and current Adilsons stock is limited to 5 units — reorder promptly if this becomes a routine staple.

Assessment: Likely Suitable, with a specific caveat below — this formula is fragrance-free (per our reconstruction) and retinoid-free, with a minimal, glycol-based preservative system rather than harsher classic preservatives.

The specific caveat: this product contains biomimetic growth-factor and peptide ingredients (sh-Oligopeptide-1/EGF and related peptides) whose interaction with active cancer treatment has not been studied for topical skincare use, and growth-factor signaling is a category some oncology teams prefer patients avoid during active treatment out of caution, independent of any skincare-specific data.

Consult your oncology care team before introducing any new skincare products during treatment.
