Medicube DEEP VITA C DAILY QUICK MASK (30pcs)

Values: 100% Genuine (Adilsons policy)*. FA-Conditional. Not Pregnancy-Safe (contains Retinol). Not Fragrance-Free (contains Parfum). Halal-Friendly*/Vegan-Friendly* — self-assessed, see Section 26.

*Genuine-product guarantee is an Adilsons store policy, not a brand certification.

Wanting brighter skin but not having time for a 20-minute mask ritual is a real, common tension — this format exists specifically to remove that excuse, not to out-perform a slower, higher-effort treatment.

PIH vs PIE: the Niacinamide/Ascorbic Acid pairing here targets PIH (brown, melanin-based marks) rather than PIE (red/pink marks from capillary damage, better served by centella or azelaic acid).

Pros: genuinely high-dose Niacinamide (per retailer marketing); quick, low-effort daily format; good value per sheet for frequent use.
Caveats: Vitamin C and Retinol both sit low in the ingredient list — don't expect this to replace a dedicated leave-on Vitamin C serum; contains fragrance (Parfum); retailer marketing's "four types of Vitamin C complex" claim could not be verified against the declared INCI, which shows only one named Vitamin C form (Ascorbic Acid).

This is a mask, not a cleanser, so it doesn't interact with the over-cleansing cycle directly — but it's often reached for as a "quick fix" after over-washing strips the skin, which can mask the real problem (a stripped acid mantle) rather than solve it. If dullness follows a change in cleansing habits, address the cleanser first, then use this mask as a supporting step.

Classification: RED. Contains Retinol (regardless of trace dose) and a meaningful Niacinamide concentration — not appropriate for prepubescent skin, which has not yet developed the sebaceous activity these actives are designed to modulate.

Safe alternatives (verified in-catalog): Medicube Super Cica Calming Mask 22g (Centella-based, no Retinol/Vitamin C actives).

1. When: AM or PM, as a quick daily layer. 2. How much: one full sheet. 3. How: unfold onto clean, dry or slightly damp skin, smooth out air bubbles, leave on for the brand's recommended short contact time, then remove and pat in the remaining essence — do not rinse.

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.

1. Cleanser → 2. Toner → 3. Deep Vita C Daily Quick Mask (in place of a serum step, short wear) → 4. Moisturizer → 5. Sunscreen SPF50+ PA++++ (mandatory, since Retinol and Vitamin C both increase photosensitivity considerations). In Mauritius humidity, a shorter mask-wear time is usually enough — the essence won't fully dry down the way it might in cooler, drier climates.

1. Double cleanse → 2. Toner → 3. Deep Vita C Daily Quick Mask → 4. Moisturizer. Since this mask contains Retinol, treat its use nights as an "active night" for skin-cycling purposes — don't also apply a separate leave-on AHA/BHA exfoliant the same evening.

Technique: Pat the remaining essence in after removing the sheet — do not rub. Required skin state: clean, dry or lightly damp. Wait time: follow the brand's short "quick mask" contact time rather than the 15-20 minutes typical of standard sheet masks — this format is designed for shorter, more frequent use.

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 runs 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 minutes. Amount defaults: toner/essence 5-8 drops; serum 2-3 drops or 1 pump; sheet mask — one sheet, brand-recommended contact time; moisturizer 1-2 peas; sunscreen 2-finger rule for the face, +1 finger for the neck. If the routine pills, stings, or feels heavy, reduce layers rather than increasing them.

AM Maximum Stack: 1. Cleanse → 2. pH-Prep Toner → 3. Hydrating Toner Layers → 4. Essence → 5. Mist → 6. Booster/Soothing Serum → 7. Antioxidant Lane (this mask can fill this slot) → 8. Pigment Support Lane → 9. Hydration Serum Lane → 10. Oil-Control Lane → 11. Peptide/Repair Lane → 12. Eye Serum → 13. Moisturizer → 14. Optional Sealing Layer → 15. Sunscreen SPF50+ PA++++ (non-negotiable) → 16. Lip SPF.

PM Maximum Stack: 1. Micellar → 2. Oil Cleanser → 3. Water Cleanser → 4. pH-Prep Toner → 5. Hydrating Toner Layers → 6. Essence → 7. Soothing/Barrier Serum → 8. This mask (anchor placement, in place of a serum) → 9. Targeted Serum (only if not conflicting) → 10. Moisturizer → 11. Sleeping Mask → 12. Occlusive Seal → 13. Spot Treatment → 14. Lip Sleeping Mask. Do not layer retinoids with AHA/BHA in the same night; keep "one lane" per night.

This mask occupies the essence/serum tier — apply after toner, before moisturizer. Because it's a saturated sheet rather than a drop-dispensed liquid, there's no dose-control the way there is with a serum; the sheet delivers a fixed amount of essence regardless of your skin's actual need that day.

Primary: daily dullness maintenance and light hydration via a high-dose Niacinamide essence. Secondary: trace Vitamin C/Retinol contribution to tone-evening over time with consistent use.

What this product cannot do: it cannot replace a dedicated leave-on Vitamin C serum or Retinol treatment for meaningful pigmentation or anti-aging results — both actives sit low in the ingredient list here, and the format's short contact time further limits their real-world impact.

Cream — primary: Deep Vita C Capsule Cream 55g — same-line moisturizer built on Sodium Ascorbyl Phosphate for continued brightening after the mask. Alternatives: TXA Niacinamide Capsule Cream 55g, Deep Vita C Capsule Serum 30ml, Deep Vita C Ampoule 2.0 30g.

Toner Pad — primary: 2024 Deep Vita C Pad 70ea 150g — same-line exfoliating/brightening pad for the routine step before this mask. Alternative: PDRN Pink Niacinamide Milky Toner 150ml.

Sunscreen — primary: Glow Collagen Sunscreen 50ml SPF50 — mandatory AM step given the Retinol/Vitamin C photosensitivity considerations. Alternatives: Collagen Firming Sun Cream 50+ SPF PA++++, PDRN Hydrating UV Serum.

Pilling: Low — the essence is largely humectant-based; avoid stacking additional heavy silicone products immediately after.

One Active Lane per routine: since this mask contains both trace Retinol and trace Ascorbic Acid, treat its use nights as your "Retinoid lane" night — don't also apply a separate leave-on AHA/BHA exfoliant or a strong L-Ascorbic Acid serum the same session. × Separate strong Vitamin C serums: don't layer this mask with a separate high-strength Vitamin C serum in the same routine — pick one Vitamin C source per session. × Prescription retinoids: if you're using prescription tretinoin/adapalene, treat this mask as a retinoid-lane product and don't combine same-night. Barrier override: if moisturizer stings or skin feels tight within 30 minutes of cleansing, pause all actives — including this mask — for 3-7 days.

Do not layer retinoids with AHA/BHA in the same night; keep "one lane" per night.

MYTH: "A daily Vitamin C mask works as well as a leave-on Vitamin C serum." REALITY: This mask's Ascorbic Acid sits low in the ingredient list with a limited contact time — it's a supportive daily boost, not a replacement for a dedicated serum with a verified concentration.

MYTH: "More sheets per day means faster brightening." REALITY: Overusing sheet masks doesn't accelerate results and can over-hydrate/macerate the skin barrier — stick to the brand's recommended daily frequency.

AC environment warning: in air-conditioned environments, the humectants in this mask's essence (Glycerin, Butylene Glycol) can draw moisture from your deeper skin layers instead of from the air. Always seal with a moisturizer after use if you'll be in AC for extended periods.

*Both Ascorbic Acid and Retinol sit near the end of the declared ingredient list — their real-world functional contribution at this SKU's dosing is likely modest despite strong evidence for these actives at effective concentrations.

Full INCI: Water, Dipropylene Glycol, Glycerin, Niacinamide, 1,2-Hexanediol, Hydroxyethyl Urea, Hydroxyacetophenone, Hippophae Rhamnoides Water, Polyglyceryl-10 Laurate, Polyglyceryl-4 Laurate, Xanthan Gum, Butylene Glycol, [--- Estimated 1% Line ---] Coptis Japonica Root Extract, Paeonia Suffruticosa Root Extract, Ethylhexylglycerin, Panthenol, Arginine, Carbomer, Disodium EDTA, Allantoin, Parfum, Menthyl Lactate, Dipotassium Glycyrrhizate, Acetyl Glucosamine, Tocopherol, Ascorbic Acid, Retinol, Polysorbate 20, BHA, BHT.

*The 1% line is estimated from typical sheet-mask essence ordering, not brand-confirmed — this reconstruction comes from WebSearch summaries of INCIDecoder/CosDNA listings, not a directly fetched primary source (both were blocked by network egress this session).

Fairy dusting: *Ascorbic Acid and Retinol both appear below the estimated 1% line, suggesting trace/marketing-level presence. *Retailer marketing describing "four types of Vitamin C Complex" could not be corroborated against the declared INCI, which names only Ascorbic Acid — treat the "four types" claim as unverified.

Preservative system: 1,2-Hexanediol, Ethylhexylglycerin, Hydroxyacetophenone, BHT, and (near the formula's end) BHA — in this position, alongside BHT, "BHA" almost certainly denotes Butylated Hydroxyanisole, a preservative-class antioxidant, not beta-hydroxy/Salicylic Acid.*

*Not independently confirmed against a primary source this session — flagged so this abbreviation isn't misread as an exfoliating acid claim.

Fragrance status: Synthetic Fragrance (Parfum) — declared as its own explicit INCI entry.*

*The term "Parfum" in the INCI list may contain undisclosed allergens. Patch test advised for sensitive individuals.

Scent: not independently described from a primary source this session; expect a light, brand-formulated scent given the explicit Parfum entry. Alcohol: Alcohol-Free (no denatured/drying alcohol identified in the declared INCI).

Halal: *Self-assessed by Adilsons based on available INCI data. No ethanol from fermentation, no porcine-derived ingredients, and no haram animal-derived ingredients detected in the declared ingredient list. 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 ingredients detected. This is NOT a formal vegan certification by The Vegan Society or equivalent body.

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

Microplastic-Free: Yes — no solid microbead-type polymer identified in the declared INCI.

MFDS Classification: Not confirmed as Functional Cosmetic status for this SKU — treat as General Cosmetic pending contrary evidence.

Whitening translation: the Korean "미백" (mibaek) classification, where it applies to Medicube's brightening lines, means regulation of melanin production to fade dark spots toward your natural tone — it does not bleach skin or change your natural complexion.

Evidence confidence: Medium for the Niacinamide contribution (retailer-stated 2% is a plausible effective dose); Low* for the Vitamin C/Retinol contribution given both sit below the estimated 1% line.

*Brand has not published SKU-specific clinical trial data for this mask.

Fungal Acne Safety: FA-Conditional. Contains Polyglyceryl-10 Laurate and Polyglyceryl-4 Laurate — the same Polyglyceryl fatty-acid-ester emulsifier family already confirmed as a recurring Medicube brand-wide pattern across multiple sub-lines. FA-prone users should patch test.

Assessment: Low. The essence is primarily humectant-based; pilling is unlikely unless layered under a heavy silicone-based product without adequate absorption time.

Individually-sealed sheets protect the essence from air exposure until opened; discard any sheet whose pouch is already open, torn, or dried out before first use. Store away from direct heat and sunlight — Mauritius bathroom humidity is not itself a stability risk for sealed, individually-wrapped sheets. Discard if the essence smells sour/off rather than its normal light scent.

Patch test on the inner forearm for 24 hours, then behind the ear for 24 hours, before full facial use — the explicit Parfum entry and the trace Retinol/Vitamin C content both warrant this more than a fragrance-free basic mask would.

72-hour barrier reset (if adverse reaction): stop all actives. For 72 hours, use only a gentle cleanser plus plain moisturizer and mineral SPF — no acids, retinoids, Vitamin C, exfoliants, or fragranced products. After 72 hours, reintroduce one product per 14 days.

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

Pregnancy-safe alternative (verified in-catalog): Medicube Super Cica Calming Mask 22g (Centella-based, no Retinol).

1. Expecting dramatic Vitamin C/Retinol results from a trace-dosed daily mask. 2. Using more than one sheet per day chasing faster results. 3. Skipping SPF the morning after use, given the Retinol/Vitamin C content. 4. Leaving the sheet on far longer than the brand's recommended "quick" contact time, which doesn't add benefit. 5. Not patch testing despite the explicit fragrance content.

At one sheet per use, a 30-pack provides roughly one month of daily use, or longer at a reduced frequency (every other day). Reorder roughly 2 weeks before expected depletion if using daily, to allow for shipping time.

This mask works best as a quick daily brightening layer inside a broader Deep Vita C routine — it's a maintenance step, not the routine's primary active driver.

AM: 1. Cleanser → 2. Deep Vita C Pad (toner step) → 3. This mask (short wear) → 4. Deep Vita C Capsule Cream → 5. SPF50+ PA++++ sunscreen.
PM: 1. Double cleanse → 2. Toner → 3. This mask → 4. Cream.

If your skin is barrier-compromised right now: skip this mask and use a plain, fragrance-free moisturizer until skin recovers.
If you are in AC for long hours: seal with a moisturizer promptly after removing the sheet.

Stock-true bundle: This mask + Deep Vita C Capsule Cream + any in-stock SPF above forms a complete, same-line AM/PM base.

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 Deep Vita C active family in a different format (Sodium Ascorbyl Phosphate instead of Ascorbic Acid, and no Retinol), Deep Vita C Glutathione Brightening Mask is a same-brand single-use sheet mask alternative. If you want a fragrance-free, active-free calming option instead, Super Cica Calming Mask 22g is a gentler pick. If you want a hydrating/plumping mask built on PDRN instead of Vitamin C, PDRN Pink Vita Coating Mask is a different active lane entirely.

This product's PRIMARY function is: quick daily Niacinamide-led brightening maintenance. You do NOT need this if you already own an unopened box of a similar daily sheet mask, or if your routine already includes a dedicated leave-on Vitamin C serum providing a stronger, verified dose. Stacking assessment: No Benefit if you're already using a strong leave-on Vitamin C serum daily and just want more Vitamin C; Marginal Benefit as a convenient daily hydration/Niacinamide top-up; Significant Benefit if you currently have no daily brightening step at all.

Quick verification tips: genuine Medicube packaging carries a QR code on the inner box resolving to medicubeverify.com; check for a short, clearly embossed batch code on the outer carton; individual sachets should be fully sealed and unpunctured.

Parent Company: APR Corporation (KRX:278470), founded in Seoul in 2014 by Byunghoon (Victor) Kim; Medicube is APR's flagship skincare/beauty-device brand, and APR went public on the Korea Exchange in 2024. Founded: 2016. Headquarters: Seoul, South Korea. Hero ingredient: PDRN (salmon-derived Sodium DNA), though this SKU sits in the separate Deep Vita C brightening sub-line. Manufacturing: confirmed in-house R&D for Medicube's AGE-R at-home devices specifically; not independently confirmed whether this SKU's topical formula is made in-house or via third-party Korean contract manufacturing.

Medicube positions itself as a "medical beauty" / dermatology-adjacent brand, pairing at-home devices with companion topical actives. Its Deep Vita C sub-line spans capsule creams, serums, ampoules, toner pads and masks — but as this SKU shows, not every product in the sub-line uses the same Vitamin C form or carries the same safety profile, so each product's own INCI is worth checking individually.

Aggregated retailer and review-site commentary describes this mask as hydrating and brightening, with at least one self-described sensitive/eczema-prone reviewer noting it adhered well without irritation and produced a brightening effect after roughly a week of use with only two applications. The quick-dispenser packaging is repeatedly praised for convenience compared to standard single-fold sheet masks. Independently-attributable verbatim reviews specific to this exact SKU (with platform and skin type named) were not found during this research pass beyond these aggregate summaries.

Common praise themes: hydrating and brightening for a low-effort daily step; adheres well without irritation for at least one reactive-skin reviewer; convenient quick-use format.

Common complaint themes: one independent review-database source flagged a higher-than-typical irritation-potential rating for the formula, not independently corroborated by a second source; the "four types of Vitamin C complex" marketing claim doesn't clearly match the single Vitamin C ingredient found in the declared INCI.

Primary Packaging: 30 individually-sealed sachets in an outer box. Hygiene Rating: Excellent (single-use, no contamination risk between uses). Travel-Friendly: Yes, individual sachets pack easily; check liquid-volume rules if traveling with the full box. Sustainability: individual sachets generate more packaging waste per use than a pump/tube format — check local recycling guidance for the sachet material.

Can I use this mask every day? Yes — it's specifically formulated as a "quick," low-effort daily mask rather than a once-weekly intensive treatment, though some users may prefer every-other-day use if sensitive.

Is it safe during pregnancy? No — it contains Retinol, and common pregnancy-safety guidance flags any formulated retinoid product as best avoided.

Does it really contain "four types of Vitamin C"? Retailer marketing makes this claim, but the declared ingredient list identified in this research only names one Vitamin C form (Ascorbic Acid) — treat the "four types" claim as unverified.

Is it fragranced? Yes — Parfum is listed as its own explicit ingredient.

Can teenagers use it? Not recommended under 16 — see the Age Suitability section above.

Niacinamide

Vitamin B3; supports the skin barrier and reduces excess pigment transfer to surface skin cells.

Ascorbic Acid

A Vitamin A derivative that speeds up skin cell turnover and supports collagen signaling at effective doses.

1% Line

The estimated point in an ingredient list below which concentrations are assumed to drop under roughly 1%.

Fairy Dusting

When a marketed ingredient is included at such a low concentration it's unlikely to have a real functional effect.

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

Best for: anyone wanting a low-effort, high-frequency brightening step to layer into a Deep Vita C routine, not a replacement for a stronger dedicated treatment. Key benefits: genuinely meaningful Niacinamide dose; convenient quick-use daily format; good hydration support. Keep in mind: Vitamin C and Retinol both sit low in the ingredient list — pair with a dedicated leave-on serum/cream for stronger results; not suitable during pregnancy/nursing or under age 16; contains fragrance.

Assessment: Consult Oncologist. This formula contains Retinol and explicit synthetic fragrance (Parfum), both commonly flagged for treatment-sensitized skin.

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