COSRX AC COLLECTION CALMING FOAM CLEANSER 50ML

Values row: 100% Genuine (Adilsons sourcing guarantee) · Halal-Friendly* · Vegan-Friendly* · Cruelty-Free* · Fragrance-containing (not fragrance-free — see Section 24).

Empathy line: Waking up to a new breakout when you already washed your face the night before is genuinely demoralizing, and it's easy to conclude your skin is "just bad." Most of the time it isn't bad — it's congested, and congestion responds to a cleanser that actually reaches inside the pore rather than one that only wipes the surface.

Pros: Low, verified BHA dose suitable for daily use; rinse-off format lowers fungal-acne and irritation risk versus a leave-on BHA; foams densely from a small amount, so 50ml lasts through a genuine trial period; travel-legal size for carry-on liquids.

Caveats: Contains a real essential oil (Lavandula Hybrida / lavender) and its two allergen constituents, so it is not a fragrance-free product despite reading as "gentle" on the label; the fatty-acid soap base can feel drying if overused on already-dry skin; the 50ml size is a trial/travel format, not a long-term-value size.

In Mauritius heat, the oil on your face by 2pm is mostly sebum and sweat doing their normal job, not "dirt" that needs scrubbing off. Washing more than twice a day, or scrubbing hard because skin "still feels oily," strips the skin's acid mantle (its natural pH 4.5-5.5 protective layer) and the skin responds by making more sebum to compensate — the exact oiliness you were trying to fix.

This cleanser is built to interrupt that cycle rather than feed it: the potassium-soap/betaine base clears surface oil and the 0.5% Salicylic Acid works specifically inside the pore on sebum-bound debris, so the mechanical scrubbing that damages the barrier isn't needed. Use it once or twice daily — not more — and let the BHA do the inside-the-pore work instead of your fingernails.

Classification: YELLOW (14+ with guidance). At 0.5%, this is a low-end, rinse-off BHA dose — well within what dermatologists generally consider appropriate for teenage acne once it's rinsed off within a minute — but it is still a real active ingredient, not a plain water-based face wash, so it isn't a blanket "any age" product.

For a genuinely younger or first-time user, a fragrance-free, active-free cleanser is the safer starting point; if breakouts persist after 4-6 weeks on a gentle cleanser, this product is a reasonable next step under a parent's or pharmacist's guidance. COSRX Low pH Good Morning Gel Cleanser is the active-free, gentler alternative in the same brand family, verified in stock at the time of writing.

1. When: AM and/or PM, daily.
2. How much: A pea-sized amount, lathered in wet palms first.
3. How: Massage onto damp skin for 30-60 seconds, avoiding the eye area, then rinse thoroughly with lukewarm water.

"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. [THIS PRODUCT] COSRX AC Collection Calming Foam Cleanser — clears overnight sebum buildup so the rest of the routine absorbs evenly.
2. Hydrating or calming toner (optional) — replaces the moisture the cleanse just removed.
3. Lightweight gel moisturizer, if your sunscreen alone isn't hydrating enough.
4. Broad-spectrum sunscreen SPF30+ (non-negotiable) — protects skin and prevents fresh acne marks from darkening under Mauritius sun.

Mauritius humidity note: humectant toners applied right after this cleanse pull moisture in from the humid morning air rather than from deeper skin layers, which is exactly when they perform best.

1. Oil cleanser (optional, only if wearing sunscreen/makeup) — dissolves oil-based residue first.
2. [THIS PRODUCT] COSRX AC Collection Calming Foam Cleanser — the water-based second step that finishes the job.
3. Targeted treatments (retinoid or leave-on exfoliant, on their scheduled nights only — see the Conflict Solver below).
4. Moisturizer, to lock hydration back in and support the barrier overnight.

Skin cycling integration: this cleanser is compatible with every night of a 4-night cycle (Exfoliation / Retinoid / Recovery / Recovery) since it's a rinse-off step, not part of the active lane itself.

Technique: Massage in circular motions on damp skin for the full 30-60 second contact window — this is the time the surfactants and BHA actually need to work, not a rinse-and-go swipe. Pat dry afterward rather than rubbing with the towel.

Required skin state: Damp skin at the start (helps it lather), rinsed with lukewarm — not hot — water, since hot water accelerates barrier stripping.

Hands vs. cotton pad: Hands deliver 100% of the product; cotton pads absorb approximately 30-40% and are unnecessary for a rinse-off cleanser anyway.

Contact lens wearers: Rinse thoroughly and avoid the immediate eye area; if product enters the eye, rinse with water.

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. Default wait times: watery layers 10-20s, serums 30-60s, 10-15 minutes before sunscreen if heading outdoors. Default amounts: toner/essence 5-8 drops per layer, serum/ampoule 2-3 drops or 1 pump, eye product half a rice-grain per eye, gel moisturizer 1-1.5 peas, cream 1-2 peas, occlusive seal rice-grain to pea-size, sunscreen the 2-finger rule for the face. If a routine pills, stings, or feels heavy, reduce layers — never increase them to compensate.

AM Maximum Stack: (1) Rinse/gentle cleanse — this product fits here; (2) pH-prep toner (optional); (3) hydrating toner layers (1-3, optional); (4) essence (optional); (5) mist (optional); (6) soothing/booster serum (optional); (7) antioxidant lane, pick one; (8) pigment-support lane, pick one; (9) hydration serum lane; (10) oil-control/sebum lane, pick one; (11) peptide/repair lane; (12) eye product; (13) moisturizer; (14) optional sealing layer (AC/dry days only); (15) sunscreen SPF50+ PA++++, non-negotiable, reapplied every 2 hours outdoors; (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 worn); (3) water cleanser — this product's primary role; (4) pH-prep toner; (5) hydrating toner layers; (6) essence; (7) soothing/barrier serum; (8) [Anchor active product] — apply on fully dry skin if it's a retinoid or exfoliant and wait accordingly; (9) targeted serum, only if non-conflicting; (10) moisturizer; (11) sleeping mask (optional); (12) occlusive seal (optional, skip if clog-prone); (13) spot treatment/pimple patch as needed; (14) lip sleeping mask. Do not layer retinoids with AHA/BHA in the same night — keep "one lane" per night.

Tier: This is a rinse-off cleanser — it doesn't occupy a layering "rung" in your leave-on stack at all, since nothing of it remains on skin after rinsing. It is always applied first, on dry or damp skin, before any leave-on product.

Rheological note: The tube dispenses as a smooth cream but transforms into a light, cushiony foam the moment water is added — judge it by how it lathers, not by how thick it looks coming out of the tube.

Barrier index gate: If your skin stings when you apply moisturizer, feels tight within 30 minutes of cleansing, or shows visible flaking, your barrier is below threshold for a BHA cleanser right now. Switch temporarily to a plain, active-free cleanser such as COSRX Low pH Good Morning Gel Cleanser and rebuild for a week before returning to this one.

• Active breakouts/blemishes: Salicylic Acid is oil-soluble and penetrates into the sebum-filled pore to break up the plug that becomes a blackhead, whitehead, or inflamed pimple.
• Excess sebum/oiliness: the surfactant base clears surface oil without the compensatory over-stripping that triggers rebound oiliness (see the Over-Cleansing Cycle above).
• Redness around breakouts: the CentellAC-RX triterpenes are calming/soothing ingredients commonly used for exactly this purpose, though at an undisclosed, likely low, concentration.
• What this product cannot do: it cannot shrink pore size (pores don't physically resize), cannot resolve deep cystic acne on its own (that needs a dermatologist), and cannot fade existing post-acne marks — that's a job for a targeted brightening serum, not a cleanser that's rinsed off in under a minute.
• Diet note: for hormonal/cystic acne, a high-glycemic or high-dairy diet is linked to elevated insulin/IGF-1 signaling that can increase sebum production — this is a topical-plus-dietary framing to be aware of, not a medical claim this cleanser addresses on its own.

Every pairing below was checked live against the Adilsons catalog for active status and real inventory at the time of writing. Stock changes constantly, so each slot lists one primary pick plus three verified alternatives.

1. Soothing/calming toner (post-cleanse hydration, redness control)

• Primary: Anua Heartleaf 77% Soothing Toner — fragrance-free, calms redness immediately after the BHA step.
• Alt 1: MIXSOON Centella Asiatica Toner
• Alt 2: SKIN1004 Madagascar Centella Hyalu-Cica Brightening Toner
• Alt 3: Anua Birch Moisture Boosting Pad

2. Oil-free/lightweight moisturizer (seals hydration without heaviness)

• Primary: iUNIK Centella Calming Gel Cream
• Alt 1: SKIN1004 Madagascar Centella Poremizing Light Gel Cream
• Alt 2: Isntree Hyaluronic Acid Aqua Gel Cream
• Alt 3: Purito SEOUL Oat-in Calming Gel Cream

3. Non-comedogenic daily sunscreen (mandatory AM step, protects acne-prone skin from post-inflammatory darkening)

• Primary: Beauty of Joseon Relief Sun: Rice + Probiotics SPF50+
• Alt 1: SKIN1004 Madagascar Centella Air-Fit Suncream Light SPF30
• Alt 2: SKIN1004 Madagascar Centella Tea-Trica Soothing Sun Milk
• Alt 3: Anua Heartleaf Silky Moisture Sun Cream

Pilling pairs: as a rinse-off product, this cleanser leaves nothing behind to pill against your leave-on layers — pilling risk from this product itself is effectively none.

This is a conflict-solver for ACTIVE ingredients. If you run multiple actives, use these rules to avoid irritation, deactivation, and barrier damage.

Universal rules: run only one primary active lane per routine (Retinoid OR Acid Exfoliation OR L-Ascorbic Acid Vitamin C OR Benzoyl Peroxide). If you break a rule, don't push through — reduce frequency, split AM/PM, or alternate nights. If moisturizer stings or skin feels tight within 30 minutes of cleansing, pause all actives and run barrier-only for 3-7 days.

This product's own lane: because the 0.5% Salicylic Acid here is rinsed off within a minute, its conflict risk is genuinely lower than a leave-on BHA toner or serum — but it still counts toward your "one active lane" if you also run a leave-on exfoliant, retinoid, or Vitamin C serum the same day. Avoid stacking this cleanser with a separate leave-on BHA/AHA product in the same routine; use this cleanser AM, and save the leave-on acid or retinoid for PM (or a different day) instead.

× Retinoids: Fine to use this cleanser on retinoid nights — cleanse, rinse, dry fully, then apply the retinoid. Don't follow it with a separate strong leave-on exfoliant the same night.

× Benzoyl Peroxide: Compatible as a cleanse step; just don't also layer a leave-on BHA/AHA the same session, since the cumulative acid load is what causes over-exfoliation, not this cleanser alone.

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

Template A — AM/PM Split: AM: this cleanser → antioxidant/soothing lane → moisturizer → SPF. PM: this cleanser (as second cleanse if wearing SPF/makeup) → retinoid OR leave-on acid lane → moisturizer.

Pre-period breakouts happen because progesterone causes the pore lining to physically swell, narrowing the opening and trapping sebum beneath — this is infundibular edema, not "dirty skin." A BHA cleanser used consistently through the luteal phase helps keep that narrowed opening clearer before it becomes a full breakout.

Chronic stress elevates cortisol, which breaks down collagen, increases transepidermal water loss, triggers inflammatory acne, and compromises barrier function — a real biological pathway, not a wellness platitude. This cleanser doesn't lower cortisol, but the CentellAC-RX complex's calming role means it's a reasonable choice to keep in a stress-flare routine rather than switching to something harsher when skin is already inflamed.

MYTH: "A harsh physical scrub cleans deeper than this." REALITY: Large, jagged scrub particles create micro-tears that worsen inflammation and can spread acne bacteria across the face; a BHA that dissolves the plug from inside the pore does the actual job without the friction damage.

MYTH: "If my skin still feels oily after washing, I need a stronger soap." REALITY: High-pH bar soaps and dish soap strip the acid mantle and trigger rebound oil production — the fix is a pH-considerate cleanser used at the right frequency, not a harsher one.

Sugar cane burning season (July-November): PM2.5 rises during harvest burns; since this cleanser rinses off completely, it doesn't trap airborne particulates the way a tacky leave-on would — no adjustment needed here specifically, but pair it with an antioxidant leave-on serum for pollution defense.

Hard water note: Mauritius tap water hardness varies by region; hard water can leave a calcium-stearate film after any soap-based cleanse that causes a tight, filmy feeling. Follow with a pH-adjusting toner (see the pairing list above) to counteract this rather than assuming the tightness means the cleanser is "too strong."

*This ingredient (the CentellAC-RX triterpene trio) appears below the estimated 1% line in the INCI list, suggesting it is present at a trace/sub-efficacious concentration. Its inclusion may be primarily for marketing rather than clinical effect.

Full INCI List: Water, Glycerin, Stearic Acid, Myristic Acid, PEG-32, Potassium Hydroxide, Palmitic Acid, Lauric Acid, Glyceryl Stearate, PEG-100 Stearate, [--- Estimated 1% Line ---], Lauramide DEA, Cocamidopropyl Betaine, Potassium Cocoate, Salicylic Acid, Sodium Chloride, Arachidic Acid, Lavandula Hybrida Oil, Linalool, Disodium EDTA, Oleic Acid, Limonene, Asiaticoside, Asiatic Acid, Madecassic Acid.

Preservative system: No dedicated preservative (paraben, phenoxyethanol, etc.) appears in the declared INCI; Disodium EDTA is present as a chelating agent (binds trace metals to protect formula stability) rather than a true preservative. This is consistent with a rinse-off, wash-away product, which needs less preservation than a leave-on formula.

Fragrance status: Contains a real essential oil (Lavandula Hybrida / Lavender Oil) — this is not a fragrance-free product, despite the calming marketing.

Scent: Mild herbal/medicinal, from the lavender oil and Salicylic Acid combined; intensity roughly 2/5, and it does not linger after rinsing.

EU 26 allergen screen: Linalool and Limonene are declared — both are naturally occurring constituents of the lavender oil, not synthetic additions, but they are still on the EU's 26-allergen disclosure list and can trigger reactions in sensitized individuals regardless of natural origin.

Alcohol disclosure: Alcohol-Free — no ethanol/denatured alcohol appears in the declared INCI.

Aspirin/salicylate sensitivity → Salicylic Acid (BHA): Salicylic Acid is chemically related to acetylsalicylic acid (aspirin). Anyone with a known aspirin allergy or salicylate sensitivity should avoid this product or get medical advice before use — this is the one cross-reactivity risk in this formula that's worth taking seriously, not a blanket "consult a doctor" disclaimer.

Halal Status: Halal-Friendly*.

*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: Vegan-Friendly*.

*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 Status: Uncertified*.

*Brand-stated policy. Not independently certified by Leaping Bunny, PETA, or an equivalent third-party audit — we checked PETA's own Beauty Without Bunnies database directly and COSRX does not appear on it. Brand states cruelty-free, but COSRX sells products in Mainland China retail, where post-market animal testing may be required by law; cross-border e-commerce sales may be exempt.

Microplastic-Free: Yes — no polymer microbeads or film-forming plastics detected in the declared INCI.

MFDS Classification: Salicylic Acid up to 2% is a recognized Korean MFDS functional-ingredient category for acne-prone skin generally, and this product is marketed within that category. No SKU-specific MFDS functional-cosmetic certificate number for this exact listing was located during research, so treat "functional cosmetic" as a general regulatory-category note rather than a confirmed certification for this bottle specifically.

Evidence confidence: Medium — Salicylic Acid's mechanism and the general Centella triterpene literature are well-established, but no SKU-specific clinical trial for this exact formula was found; the CentellAC-RX complex's efficacy is described only in brand marketing material, not an independently published dataset.

Reformulation note (moderate confidence): General COSRX AC Collection research indicates a brand "renewal" reformulation around 2021 that shifted the Centella component from a raw plant extract to the three isolated triterpenes now named on the label (asiaticoside, asiatic acid, madecassic acid). This detail came from aggregator/community-level web sources rather than a first-hand brand changelog, so treat it as plausible context rather than a confirmed fact about this exact SKU.

Fungal Acne (Malassezia) Compatibility: FA-Conditional. The formula contains several fatty acids (stearic, myristic, palmitic, lauric, oleic) that are commonly flagged as Malassezia-feeding in leave-on products. As a rinse-off cleanser with under a minute of skin contact, the real-world risk is meaningfully lower than in a leave-on product with the same fatty acids — but if you're specifically fungal-acne-prone and reactive to everything, patch test before committing.

Assessment: None. As a rinse-off cleanser, nothing remains on skin to interact with (and pill against) your leave-on layers. If you notice residue after rinsing, it's most likely hard-water calcium-stearate film rather than the cleanser itself — see the Climate Fit section above for the fix.

Color baseline: Off-white to very pale cream. A shift toward yellow or a sharp change in smell suggests oxidation or spoilage rather than normal aging.

Storage: Keep the tube capped and out of direct sun; Mauritius bathroom heat and humidity accelerate degradation of any surfactant-based formula faster than a cool, dry cabinet would.

Spoilage signs: Separation that won't remix with a shake, a sour or rancid smell replacing the herbal scent, or a texture that turns grainy. When in doubt, discard rather than risk it on broken-out skin.

1. Apply a small amount behind the ear or on the jawline.
2. Lather, rinse as normal, pat dry.
3. Wait 24-48 hours, watching for redness, itching, or burning.
4. If no reaction, it's reasonably likely safe for facial use — discontinue at the first sign of irritation.

72-Hour Barrier Reset: if you get an adverse reaction, STOP ALL ACTIVES. For 72 hours, use ONLY a gentle cleanser, a plain moisturizer, and mineral SPF. No acids, retinoids, Vitamin C, exfoliants, or essential-oil products. After 72 hours, reintroduce one product per 14 days.

Emergency stop signals: hives, swelling, blistering, persistent burning, or breathing difficulty — seek emergency care immediately, don't wait it out.

Pregnancy note: At 0.5%, this product's Salicylic Acid concentration is well below the levels generally flagged as a pregnancy concern (that threshold is typically cited around 2% and above for leave-on products). It doesn't meet this skill's pregnancy-contraindication criteria, but as with any active ingredient, pregnant or breastfeeding users should mention it to their OB or dermatologist as routine practice, not because of a specific known risk at this dose.

1. Using it more than twice daily — this strips rather than treats.
2. Skipping sunscreen afterward, which lets any new post-acne mark darken instead of fading.
3. Combining it with a separate leave-on BHA/AHA the same day and wondering why skin gets irritated.
4. Using hot water to "really clean" — it accelerates barrier stripping, not cleansing.
5. Leaving it on the sink counter in direct sun/heat, which shortens its stable shelf life.

Usage math: At roughly 0.5ml per use (a pea-sized amount) from a 50ml tube, that's approximately 100 uses per tube.

Lifespan: Used once daily, a 50ml tube lasts roughly 3 months; used twice daily, roughly 1.5 months. Using more than the recommended pea-size shortens this without improving results.

Reorder timing: Plan to reorder about two weeks before you expect to run out, to allow for shipping time.

This cleanser's job is the first, water-based step of both your AM and PM routine — it doesn't replace treatment serums or moisturizer, it prepares skin for them. Numbered routine: AM — (1) this cleanser, (2) soothing toner, (3) lightweight gel moisturizer if needed, (4) SPF. PM — (1) oil cleanser if wearing SPF/makeup, (2) this cleanser (bold anchor step), (3) treatment/active, (4) moisturizer.

If your skin is barrier-compromised right now (stinging, flaking, tight), pause this cleanser and use a plain active-free cleanser for a week before returning.

If you're in AC for long stretches, follow this cleanser with a hydrating toner layer, since AC air pulls moisture from skin rather than the reverse.

If you're in your luteal phase and notice more breakouts, keep this cleanser at its normal frequency rather than scrubbing harder — the pore-lining swelling that causes pre-period breakouts responds to consistency, not intensity.

Stock-true bundle — "Acne-Prone Starter Set" (AM-focused): this cleanser → Anua Heartleaf 77% Soothing Toner → Beauty of Joseon Relief Sun SPF50+. Cleanse, tone to calm redness, protect with SPF to prevent PIH.

Stock-true bundle — "PIH Prevention Set" (PM-focused): this cleanser → Anua Niacinamide 10% + TXA 4% Serum → iUNIK Centella Calming Gel Cream. Cleanse, target post-acne marks, seal with a lightweight moisturizer.

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

The recommendations above are based on formulation synergy with COSRX AC Collection Calming Foam Cleanser, 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 your primary concern is active breakouts and oiliness, this is a solid, verified-dose choice. If your skin doesn't actually break out much, or is more sensitive than oily, a gentler active-free cleanser is the better fit — using a BHA cleanser you don't need doesn't add benefit, it just adds irritation risk.

Primary alternative: COSRX Low pH Good Morning Gel Cleanser 150ml — same brand family, no active BHA, a fragrance-lighter daily-maintenance option (the 50ml size of this same product was out of stock at the time of writing; the 150ml is in stock).

• Alt 1: IsNtree Hyaluronic Acid Low-pH Cleansing Foam
• Alt 2: APRIL SKIN Calendula Low-pH Foam Cleanser
• Alt 3: COSRX Low pH Niacinamide Micellar Cleansing Water (ultra-gentle, non-foaming option for very reactive skin)

Mindful consumption note: If you already have a cleanser at home that's working, finish it first — switching products mid-way makes it harder to tell what's actually helping your skin.

Choose this cleanser over the Low pH Good Morning Gel Cleanser if you need active breakout control: the 0.5% Salicylic Acid works inside the pore on existing congestion, which a plain active-free gel cleanser cannot do.

Upgrade triggers (IF/THEN): If you have recurring blackheads/whiteheads on the nose and chin, THEN this cleanser's BHA addresses that congestion directly. If you're barrier-compromised right now (stinging, flaking), THEN do not upgrade yet — repair the barrier first with the plain alternative. If you're fragrance-sensitive and reactive to essential oils, THEN the alternative is the safer daily choice regardless of your acne status.

Don't upgrade if: your skin is currently dry or flaking; you're already running a leave-on BHA/AHA elsewhere in your routine and don't need a second acid source; or you have a known aspirin/salicylate allergy.

Decision close: If you match the active-breakout trigger above and have no fragrance sensitivity, this is worth choosing. If not, the alternative is sufficient and safer. Consistency beats complexity.

A real strength ladder exists in this catalog: start with COSRX Low pH Good Morning Gel Cleanser (no active, barrier-building baseline) → move to this cleanser (0.5% rinse-off BHA) once breakouts appear or persist → graduate to a leave-on BHA product once congestion doesn't resolve with a rinse-off BHA alone and your barrier can tolerate a leave-on acid. Anua's 2% BHA Gentle Exfoliating Toner is the catalog's natural next step on this ladder, but it was out of stock at the time of writing — we're not linking it while it's unavailable; check back or ask us on WhatsApp for restock timing. Each step up trades lower irritation risk for higher active exposure — don't skip a step just because results feel slow.

This product's PRIMARY function is: rinse-off BHA cleansing for active breakouts and clogged pores. You do NOT need this if you already own an unopened or barely-used BHA cleanser doing the same job — finish that one first, since its 12-month PAO clock is already running whether you use it or not.

Stacking assessment: No Benefit if you already run a separate leave-on BHA/AHA and a plain cleanser (adding this on top is redundant acid exposure, not extra benefit). Significant Benefit if your current cleanser has zero active ingredients and you're dealing with ongoing congestion — different mechanism, real addition.

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 tubes carry a batch/date code printed directly on the crimp or base (not on an applied sticker); the barcode should be crisp and printed, not blurry or misaligned; COSRX also runs an official product-authenticity QR tool at official.cosrx.com/record for stock carrying a scannable code.

COSRX is a South Korean skincare brand founded in 2013 in Seoul, built around a minimal, low-pH, "skin-friendly" formulation philosophy — simple, targeted actives over long ingredient lists. In October 2023, COSRX was acquired by Amorepacific Corporation, though the brand still trades on its original independent, ingredient-focused positioning.

The brand's best-known line is Advanced Snail (built on snail secretion filtrate), alongside the AC Collection this cleanser belongs to, the AHA/BHA line, and the niacinamide-focused Full Fit line. Whether COSRX now manufactures in-house or via contract manufacturers post-acquisition was not independently confirmed in this research pass.

Community reviews for this specific product were not located as individually attributable, verifiable text in this research pass — searches of Reddit (r/AsianBeauty, r/SkincareAddiction), Amazon, and aggregator sites like Skinsort returned only thin, unattributable rating snippets (e.g., a single aggregate "5.0/5" rating with no quotable review text) rather than real, quotable reviews for this exact formula.

Rather than inventing plausible-sounding quotes, we're stating this plainly: if you've used this product and want to share your experience, that feedback genuinely helps future customers more than anything we could write here.

Sustainability: The plastic tube and cap can typically go into local plastic recycling once fully empty and rinsed — check current Mauritius recycling guidelines, since acceptance varies by plastic type and collection point.

Can I use this cleanser every day?

Yes — it's formulated for daily AM/PM use. If your skin runs dry, once daily (PM) is a safer starting frequency.

Will this remove waterproof makeup or sunscreen on its own?

Not reliably. For heavy or waterproof makeup/sunscreen, use it as the second step after an oil cleanser rather than expecting it to do both jobs.

I have an aspirin allergy — can I use this?

Salicylic Acid is chemically related to aspirin (acetylsalicylic acid). If you have a known aspirin allergy, avoid this product or check with your doctor first.

Is this the same as the 150ml version?

Same formula, different size — Adilsons carries both as separate listings. Choose based on how much you want to commit to before deciding if it works for you.

Can I use this if I'm on prescription acne treatment (tretinoin, adapalene)?

The rinse-off contact time makes this lower-risk than a leave-on acid, but combining any BHA with prescription retinoids/acids can increase irritation — check with your prescribing dermatologist before adding it.

BHA (Beta-Hydroxy Acid)

An oil-soluble exfoliant — Salicylic Acid is the most common example — that can get inside oily pores rather than just working on the skin surface.

Acid mantle

The skin's naturally slightly acidic (pH 4.5-5.5) protective surface layer; over-cleansing strips it and can trigger rebound oiliness.

Centella Asiatica

A plant extract known for soothing, calming, and skin-repair properties; often called "Cica."

Triterpene

A type of plant-derived compound (asiaticoside, asiatic acid, and madecassic acid are examples) associated with skin-calming and barrier-support effects.

INCI

International Nomenclature of Cosmetic Ingredients — the standardized ingredient list format you see on the label.

PAO (Period After Opening)

The open-jar icon with a number (e.g., "12M") showing how many months a product stays safe to use after opening.

Purging vs. reaction

Purging is temporary increased breakouts in your usual problem areas from faster cell turnover; a reaction shows up in new areas and gets worse, not better, over time.

Fungal Acne (Malassezia)

A yeast-driven form of breakout that certain fatty ingredients can worsen in leave-on products; rinse-off contact lowers this risk considerably.

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

Assessment: Consult Oncologist. This formula contains a real essential oil (lavender/Lavandula Hybrida Oil) with its associated fragrance allergens (linalool, limonene), and a 0.5% BHA active — both categories that oncology skincare guidance commonly asks patients to avoid or check first during active treatment, since treated skin can be more reactive to fragrance and exfoliating acids.

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

Hard water interaction: This is a fatty-acid soap-based cleanser (stearic, myristic, palmitic, lauric acids saponified with potassium hydroxide), which is exactly the chemistry that reacts with hard water's calcium and magnesium ions to form the filmy "soap scum" residue (calcium stearate) that can feel like tightness on skin. In Mauritius regions with harder tap water, a brief pH-adjusting toner pass afterward neutralizes this film rather than leaving it to be mistaken for over-drying.

Best for: Anyone with oily, combination, or genuinely acne-prone skin who wants a daily BHA cleanser at a verified, moderate 0.5% dose rather than guessing at an unlabeled "acne cleanser."

Key benefits: A confirmed, brand-disclosed active concentration; rinse-off format that lowers fungal-acne and over-exfoliation risk compared with a leave-on BHA; dense, non-stripping foam that doesn't leave skin squeaky.

Keep in mind: It is not fragrance-free (real lavender oil, with linalool and limonene) despite reading as gentle; it can be too much for dry or already-compromised skin used daily; and the 50ml size is a trial format, not a long-term stock-up size.
