Dr.Althea 345 Cream Mask

100% Genuine · Fragrance-Free · Vegan-Friendly* · Pregnancy-Safe (no retinoids, acids, hydroquinone, or chemical UV filters found in the declared INCI)

*Vegan-Friendly: Self-assessed by Adilsons based on available INCI data. No animal-derived ingredients detected. Retailer marketing also describes this line as "vegan-certified," but no single named certifying body was consistently corroborated in our research — treat the certification claim itself as unconfirmed even though the ingredient list itself is genuinely animal-free.

For skin that's had a rough day — sunburn-adjacent flush from a beach afternoon, a sudden breakout, or just general Mauritius-heat fatigue — this is designed as a quick, low-commitment reset rather than a daily ritual you have to remember to keep up.

Pros: Fragrance-free and low-irritation formula; genuinely soothing cream texture, not a thin watery essence; single-sheet format means no waste from an unused multi-pack; fits any skin type as an occasional treatment.

Caveats: Sold here as a single 25g sheet, not the 4-pack many retailers carry, so it's a one-time treatment per purchase; most hero actives (Madecassoside, Ceramide NP) sit below the estimated 1% line, so treat them as supporting rather than primary actives; no independently verified clinical study behind the "reduces redness" claim.

This is not a cleansing product, but the same Mauritius heat-and-humidity cycle that drives over-washing also drives skin toward chronic low-grade redness and a compromised acid mantle (target pH 4.5-5.5) — a cream sheet mask like this one is a legitimate way to hydrate and calm skin without adding more surfactant contact on top of an already-stripped barrier.

Because the essence is delivered passively through a cellulose sheet rather than rubbed in, there's no added friction or surfactant exposure — just Niacinamide, Centella, and Tea Tree Leaf Water sitting on the skin for 10-15 minutes to calm and rehydrate.

Step 1 (When): AM or PM, as an occasional treatment — not a daily replacement for your moisturizer.

Step 2 (How much): One full sheet covers the face.

Step 3 (How): Cleanse and tone first, unfold the sheet onto clean skin, leave 10-15 minutes, remove, then pat the remaining essence into skin instead of rinsing.

"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. Gentle cleanser.
2. Toner (5-8 drops).
3. Dr.Althea 345 Cream Mask — 10-15 minutes, then pat in remaining essence (occasional-use step, not every morning).
4. Any AM serum you're using.
5. Moisturizer.
6. SPF50+ PA++++, non-negotiable.

Mauritius humidity note: because the essence is already humectant-rich, a lighter moisturizer than usual is often enough right after this mask — heavy layering on top can feel greasy in humid mornings.

1. Double cleanse if wearing SPF/makeup.
2. Toner.
3. Dr.Althea 345 Cream Mask — 10-15 minutes, then pat in remaining essence.
4. Any PM serum you're using (skip if skin still feels sensitive from a recent breakout or sun exposure).
5. Moisturizer.

Skin cycling integration: This fits best as a Recovery-night product — use it on a night you would otherwise skip actives (e.g. the night after an exfoliation or retinoid night), not stacked with strong actives on the same evening.

Technique: Unfold fully and smooth from the center outward so the sheet sits flush against skin, especially around the nose and jawline, for even essence transfer.

Required skin state: Clean, toned skin — apply after cleansing and toning, not on top of a full serum/moisturizer routine.

Wait time: 10-15 minutes; removing earlier under-delivers the soothing effect, and leaving it on much longer risks the sheet drying out and pulling moisture back out of skin instead of depositing it.

Pat, don't rub, the remaining essence into skin after removing the sheet — friction on freshly-hydrated skin increases irritation risk rather than helping absorption.

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, serums 30-60s, sunscreen 10-15 min before sun. Amount defaults: toner 5-8 drops, serum 2-3 drops/1 pump, eye product ½ rice-grain per eye, gel moisturizer 1-1.5 peas, cream 1-2 peas, sunscreen 2-finger rule for face +1 finger for neck. Hydrators go on slightly damp skin; retinoids on fully dry skin; if the 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, choose one (8) pigment support lane, choose one (9) hydration serum lane, optional (10) oil-control lane, choose one (11) peptide/repair lane, optional (12) eye cream, optional (13) moisturizer (14) optional sealing layer if dry/AC (15) SPF50+ PA++++, non-negotiable (16) lip SPF, optional. 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 wearing SPF/makeup (3) water cleanser, second cleanse (4) pH-prep toner, optional (5) hydrating toner layers, optional (6) essence, optional (7) soothing/barrier serum, optional (8) [Anchor: 345 Cream Mask, occasional-use step] (9) targeted serum, optional, only if non-conflicting (10) moisturizer (11) sleeping mask, optional (12) occlusive seal, optional (13) spot treatment/pimple patch, as needed (14) lip sleeping mask, optional. Do not layer retinoids with AHA/BHA in the same night; keep one lane per night.

One-lane rule: 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 — barrier/hydration — and reduce layers.

The essence itself is a medium-viscosity cream-gel, applied via sheet rather than dropper — it sits at the "treatment" tier in the routine, meaning it goes on cleansed/toned skin and gets followed by a normal moisturizer, not layered under other serums.

Phase compatibility: Primarily water-phase with light emollient esters (Triethylhexanoin, Caprylic/Capric Triglyceride) — light enough not to block a moisturizer applied afterward.

Purge vs Reaction: This formula is not purge-triggering (no exfoliating or cell-turnover actives) — any new redness or bumps after use should be treated as a reaction, not purging, and the product discontinued.

Before starting this product, no specific prerequisite routine is required — it is a low-risk, occasional-use treatment suitable as an early addition to any routine.

Redness and irritation: Centella Asiatica (leaf water + extract) and Madecassoside support calming; Tea Tree Leaf Water (brand-stated 30% of the base) adds an additional soothing layer.

Post-blemish recovery: Niacinamide supports even tone and barrier function around healing blemishes.

Secondary benefit: Hydrolyzed Hyaluronic Acid and Sodium Hyaluronate add a hydration boost alongside the calming effect.

What this product cannot do: It cannot fade existing dark spots or scars (that needs a dedicated brightening active used consistently over weeks) and it cannot replace a daily moisturizer — it is an occasional supplement to a routine, not its foundation.

Every recommendation below was checked against the live Adilsons catalog on 2026-09-10 for both status and actual inventory — not status alone.

• Primary — Soothing toner to prep skin beforehand: MIXSOON Centella Asiatica Toner 150ml (in stock).
• Alternative 1: Anua Heartleaf 77% Soothing Toner 250ml (in stock).
• Alternative 2: SKIN1004 Madagascar Centella Hyalu-Cica Brightening Toner 30ml (in stock).
• Alternative 3: Dr.Althea Skin Relief Essence 30ml (in stock).

• Primary — Barrier moisturizer to seal in the essence afterward: Dr.Althea 345 Relief Cream 15ml (in stock, same 345 line, formulation-matched).
• Alternative 1: Dr.Althea 147 Barrier Cream 15ml (in stock).
• Alternative 2: Dr.Althea Aqua Marine Watery Cream 50ml (in stock).
• Alternative 3: Dr.Althea PDRN Reju 5000 Cream 20ml (in stock).

Pilling pairs: Low risk — the light cream-gel essence absorbs well; if you do pat on a very thick occlusive afterward, wait a full minute for the essence to fully absorb first.

MYTH: "Leaving a sheet mask on longer than recommended gives extra benefit." REALITY: Once the sheet starts to dry out (usually past 15-20 minutes), it begins pulling moisture back out of the skin rather than depositing it — set a timer rather than leaving it on indefinitely.

MYTH: "A cream sheet mask can replace my daily moisturizer." REALITY: This is an occasional, intensive treatment layer, not a daily-use product — your routine still needs a standing moisturizer for consistent barrier support.

MYTH: "More frequent masking heals blemishes faster." REALITY: Post-blemish recovery is driven by consistent daily actives like Niacinamide in a leave-on serum; an occasional mask supports comfort during that process but isn't the primary driver of the timeline.

AC environment note: Because this mask delivers a burst of hyaluronic-acid hydration, seal it with a moisturizer afterward if you'll be in air conditioning for hours — otherwise the humectants can pull moisture from deeper skin layers instead of the air.

*Madecassoside, Tea Tree Leaf Water, and Ceramide NP: evidence for the ingredient class is solid in the general literature, but this SKU's own concentrations are not brand-disclosed, so treat the specific-product effect size as unverified rather than assuming lab-study-level potency.

Full INCI list (Aqua through Tromethamine estimated above the 1% line; everything after is estimated below it):

Aqua (Water), Tea Tree Leaf Water, Methylpropanediol, 1,2-Hexanediol, Butylene Glycol, Glycerin, Niacinamide, Octyldodeceth-16, Triethylhexanoin, Caprylic/Capric Triglyceride, Pentylene Glycol, Carbomer, Hydroxyethylcellulose, Tromethamine [--- Estimated 1% Line ---] Allantoin, Trehalose, Caprylyl Glycol, Ethylhexylglycerin, Dipotassium Glycyrrhizate, Disodium EDTA, Panthenol, Soybean Seed Extract, Sodium Hyaluronate, Hydrolyzed Hyaluronic Acid, Pantothenic Acid, Centella Asiatica Leaf Water, Cyclodextrin, Centella Asiatica Extract, Hydrogenated Lecithin, Madecassoside, Ceramide NP, Cholesterol, Camellia Sinensis Leaf Water, Resveratrol, Beta-Glucan, Sodium DNA, Nelumbo Nucifera Leaf Extract.

*Sourced via WebSearch cross-referencing INCIDecoder's listing and multiple independent retailer ingredient pages; the primary INCIDecoder and brand pages themselves could not be directly fetched this session (network egress restriction), so treat this as corroborated-medium-confidence rather than a direct primary-source read. Note: some brand marketing describes a "3 blemish-relief ingredients" set including Tannic Acid for the 345 line generally — Tannic Acid does NOT appear in this exact SKU's declared INCI, so it is not listed here as present in this product.

Preservative system: 1,2-Hexanediol, Pentylene Glycol, Caprylyl Glycol, and Ethylhexylglycerin — a multi-glycol preservative-boosting system, plus Disodium EDTA as a chelator.

Fragrance status: Fragrance-Free — no Parfum/Fragrance or added essential oil beyond the Tea Tree Leaf Water and Camellia Sinensis Leaf Water botanical waters, which are functional base ingredients rather than fragrance additions.

Scent: Very faint, herbal-neutral; most reviewers describe it as essentially unscented.

EU 26 allergen screen: None of the 26 named EU allergens (e.g. Limonene, Linalool, Citral) appear in the declared INCI list.

Alcohol disclosure: Alcohol-Free (no ethanol/denatured alcohol in the declared INCI).

Halal status: *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 status: *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 — retailer marketing describes this line as "vegan-certified" but no consistently-named certifying body was found.

Cruelty-free status: *Brand-stated policy. Not independently certified by Leaping Bunny, PETA, or equivalent third-party audit. Dr.Althea's mainland-China retail footprint is unresolved from available sources, so a China-retail caveat cannot be confidently ruled in or out at this time.

Microplastic-Free: Yes — no polyethylene, nylon, or acrylate microbeads detected in the declared INCI.

MFDS classification: General Cosmetic — no evidence found of Functional Cosmetic registration for this SKU.

"Clinically tested to reduce redness":* *Repeated across retailer marketing copy with no named institution, sample size, or methodology disclosed. Treated as a marketing claim rather than a verified clinical result.

Evidence confidence: Low-Medium for the specific redness-reduction claim; Medium-High for the general soothing mechanism of Centella/Niacinamide as ingredient classes.

Fungal Acne Safety: FA-Conditional. Hydrogenated Lecithin and Octyldodeceth-16 are flagged with caution on some Malassezia-feeding ingredient references, but at their likely below-1% concentration in a single, occasional-use sheet mask, real-world FA risk is low for most users.

Assessment: Low. The cream-gel essence absorbs cleanly; if layering a very thick occlusive immediately after, wait about a minute for full absorption first.

Color baseline: The essence should be a clear-to-milky, uniform liquid soaking the sheet. Discoloration or an off (sour/rancid) smell signals it's time to discard rather than use.

Storage: Keep the sealed sachet away from direct heat; Mauritius bathroom humidity can degrade the sachet seal over long storage, so use within the printed expiry rather than stockpiling for years.

Spoilage signs: A torn or leaking sachet, an off smell, or a discolored essence — when in doubt, discard.

Patch test: Apply a small amount of the essence to the inner forearm for 24 hours before your first full facial use, especially if you have a known Tea Tree or Centella sensitivity.

72-Hour Barrier Reset: If adverse reaction occurs, 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 — seek emergency care immediately and discontinue use.

1. Leaving the sheet on well past 15-20 minutes. 2. Rubbing rather than patting the leftover essence in. 3. Treating it as a daily moisturizer replacement. 4. Skipping a follow-up moisturizer, letting the humectants evaporate without being sealed in. 5. Applying it directly over an actively weeping or broken blemish.

Overuse threshold: There is no established upper frequency limit for this gentle formula, but using it daily provides diminishing returns versus a proper daily moisturizer and active-serum routine — treat it as an as-needed comfort tool.

Usage math: This is a single 25g sheet — one full-face application, used once.

Lifespan: This is a single-use product; there is no multi-use lifespan to calculate.

Reorder timing: If you find this format helpful, consider ordering a few sheets at once for your next hot, sun-exposed day or post-blemish flare-up, rather than reordering one at a time.

This product's job is a fast, single-use calming and hydrating reset — it sits between toner and moisturizer on the occasional day your skin needs extra comfort, not as a daily fixture.

1. Cleanse.
2. Toner, 5-8 drops.
3. 345 Cream Mask — 10-15 minutes, pat in remaining essence.
4. Moisturizer, 1-2 peas.
5. SPF (AM only).

If your skin is flushed from sun exposure today, use this mask before bed rather than waiting — the sooner the calming actives are applied after the flare, the more comfort you get from a single sheet.

If you're in the middle of a strong-active routine (retinoid or acid exfoliant), this mask makes an ideal recovery-night substitute for your usual serum step — skip the active that night and let this carry the comfort load instead.

Stock-true pairing: MIXSOON Centella Asiatica Toner 150ml (in stock, pre-mask prep) + this mask + Dr.Althea 345 Relief Cream 15ml (in stock, same-line moisturizer to seal in results).

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

The recommendations above are based on formulation synergy with the 345 Cream 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 a leave-on soothing product for daily rather than occasional use, a Centella-based toner is the closest same-goal, everyday alternative — the mechanism is similar (Centella/soothing botanicals) but the format and use-frequency differ.

The MIXSOON Centella Asiatica Toner 150ml (in stock) is the closest in-stock daily-use alternative in our catalog — it delivers similar calming botanicals in a leave-on, every-day format rather than an occasional intensive sheet treatment.

This product's PRIMARY function is: a single-use, cream-essence soothing and hydrating treatment. You do NOT need this if you already have an unopened box of the same or a very similar Dr.Althea 345-line sheet mask, or if your standing routine already includes a strong daily soothing serum/toner and skin is currently calm.

Stacking assessment: Significant Benefit if paired occasionally with a daily Niacinamide/Centella routine (different delivery format, added intensive boost); No Benefit if used back-to-back with another intensive soothing mask on the same day.

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: Genuine Dr.Althea units carry an EAN-13 barcode beginning with 880 (Korea's country prefix); check for a rectangle-shaped HiddenTag authentication label you can scan with the free HiddenTag app; you can also cross-check the printed batch code at CheckFresh for a manufacture-date match.

Dr.Althea is a Korean derma-cosmetic brand founded in 2014 and headquartered in Seoul, consistently described across independent retailers as founder-led by Evelyn Lee. No evidence of a separate parent company was found — available sources point to it being independently held.

The brand's "345" line, which this mask belongs to, is built around a named "3-4-5 Complex" framework (3 blemish-relief, 4 nourishing, 5 soothing ingredients) applied with formula variations across a cream, cream mist, serum, spot powder, and this cream mask — all sharing the same underlying philosophy of gentle barrier support for reactive and post-blemish skin.

An independent blogger review (lola's secret beauty blog, February 2026), dedicated specifically to this exact mask, reported that it immediately calmed irritated skin, appeared to speed up visible blemish/redness recovery, and left skin hydrated with a creamy, non-greasy essence.

Broader retailer/marketplace copy corroborates the same core themes — soothing on application, no greasy residue, comfortable for sensitive skin — though this is aggregate marketing language rather than individually attributable reviewer quotes.

A direct search for Reddit threads on r/AsianBeauty and r/SkincareAddiction specific to this exact SKU did not surface a dedicated discussion at the time of writing.

Is this the same as the 4-pack I've seen online? This Adilsons listing is a single 25g sheet, not the 4-sheet set sold by some other retailers — the formula is identical, just the quantity differs.

How long should I leave it on? 10-15 minutes. Beyond that, the sheet can start to dry out and pull moisture back out of your skin rather than depositing it.

Can I use this every day? You can, since the formula is gentle and fragrance-free, but it's designed as an occasional intensive treatment rather than a daily-use product — a standing toner/serum routine is more efficient for everyday soothing.

Does it actually reduce redness? Retailer marketing claims clinical testing for redness reduction, but no named study or methodology was found — treat it as a plausible, ingredient-supported claim rather than an independently verified one.

Is it fragrance-free? Yes — the declared INCI shows no added Parfum/Fragrance, and the only scent-adjacent ingredients are functional botanical waters (Tea Tree, Camellia Sinensis).

Cellulose sheet mask

A sheet made from plant-fiber-derived material (rather than cotton or synthetic fiber) designed to hold and release essence evenly onto skin.

Madecassoside

A calming compound isolated from Centella Asiatica, studied for supporting skin repair and reducing inflammation.

Niacinamide

A form of Vitamin B3 that supports barrier function, even tone, and oil regulation.

Humectant

An ingredient (like Hyaluronic Acid) that draws water into the skin's surface layers.

Occlusive

An ingredient that forms a light film on skin to reduce water loss — used here in the moisturizer step, not the mask itself.

Patch test

Applying a small amount to a discreet area (forearm) before full facial use, to check for a reaction.

Best for: Anyone who wants a fast, single-use calming treatment for flushed, sun-warmed, or freshly irritated skin, or a comfort layer during post-blemish recovery.

Key benefits: Fragrance-free, low-irritation formula; genuinely creamy, non-sticky essence; no retinoids or acids to worry about for pregnancy or barrier safety; fits any skin type as an occasional add-on.

Keep in mind: This is a single 25g sheet, not a multi-pack; most named hero actives sit below the estimated 1% line, so treat this as a supportive comfort product rather than a primary treatment; the "clinically tested" redness claim isn't independently documented.
