The Ordinary AHA 30% + BHA 2% Peeling Solution [30ml]

Values: 100% Genuine (Adilsons policy) · FA-Conditional (Polysorbate 20 present, generally low-risk) · Fragrance-Free (confirmed via declared INCI) · Halal-Friendly* / Vegan-Friendly* (self-assessed, see Section 26) · Not Pregnancy-Safe (see safety notice above).

Empathy line: If congested skin and post-breakout marks have you scrubbing harder or washing more often, this isn't a "more is better" product — it works in one deliberate 10-minute session, not through daily grinding at your skin.

Pros: Very high total acid concentration for fast texture change; targets both surface (AHA) and inside-the-pore (BHA) congestion in one step; rinse-off design limits prolonged skin contact versus a leave-on acid; brand-disclosed pH and acid blend rather than a vague "exfoliating complex."

Caveats: Not beginner-friendly — this is the strongest single product in The Ordinary's exfoliating range; strict 10-minute timing is non-negotiable; requires a genuinely healthy barrier and a consistent SPF habit before you start.

Classification: RED. This is not suitable for anyone under 16. The 30% total AHA plus 2% salicylic acid load is designed to accelerate desquamation (shedding of the outermost skin layer) and dissolve sebum inside pores — processes that pre-teen and early-teen skin, which has a thinner stratum corneum and a still-developing acid mantle, is not biologically prepared to tolerate at this intensity.

Packaging note: The Ordinary's bottle and box are deliberately plain and clinical, not youth-marketed — but the brand's accessible positioning and heavy TikTok/social-media visibility have made its strongest actives, including this exact product, widely reported as something teens and tweens pick up without adult guidance. Plain packaging does not mean low risk here.

Safer alternatives (verified in Adilsons' catalog): for teens who want a routine without acids at this strength, start with a low-pH gentle cleanser such as COSRX Low pH Good Morning Gel Cleanser, a barrier moisturizer such as Dr.Althea 147 Barrier Cream, and daily SPF such as SKIN1004 Hyalu-Cica Water-Fit Sun Serum. If texture or congestion genuinely needs addressing at 16+, a much gentler entry point is the SOME BY MI AHA-BHA-PHA 30 Days Miracle Toner, used under adult guidance, never this peeling solution.

Step 1 — When: PM only, on a night with nothing else new in your routine.

Step 2 — How much: A thin, even layer across the face (avoiding eyes, lips, and any broken skin) — roughly a nickel-to-coin-sized pool worked evenly with fingertips, not cotton.

Step 3 — How: Apply to clean, fully dry skin; set a timer for 10 minutes; rinse thoroughly with lukewarm water the moment it goes off, sooner if it burns rather than tingles.

Introduce this as the ONLY new product in your routine. Wait a full 14 days before adding anything else. This isolation window ensures you can identify whether any reaction is caused by this specific product.

This is a PM-only product. Using it in the morning risks daytime sun sensitivity on freshly exfoliated skin, and the 10-minute rinse-off timing doesn't fit a rushed morning routine.

Mandatory SPF statement: because acid exfoliation temporarily increases photosensitivity, every morning after a peel night — and every morning generally while this product is in your routine — needs a broad-spectrum SPF50+ PA++++ sunscreen, non-negotiably.

A typical AM sequence the day after: gentle cleanser (optional, if skin feels oily on waking) → hydrating toner (optional) → antioxidant serum (optional) → moisturizer → SPF50+ PA++++. Humid Mauritius mornings mean humectant layers like hyaluronic acid draw water from the air rather than your skin, so one thin layer is usually enough.

1. Double cleanse if wearing sunscreen/makeup, or a single gentle cleanse otherwise.
2. Pat skin fully dry — do not apply to damp skin.
3. Apply The Ordinary AHA 30% + BHA 2% Peeling Solution in a thin, even layer, avoiding the eye and lip area.
4. Set a 10-minute timer; rinse thoroughly with lukewarm water.
5. Apply a barrier moisturizer immediately after rinsing, while skin is still slightly damp.

Skin cycling integration: this product occupies the Exfoliation-lane night in a 4-night cycle — Night 1 this Peeling Solution, Night 2 recovery, Night 3 retinoid (if used), Night 4 recovery — never on the same night as a retinoid or another strong acid.

Technique: Pat/press to apply, do not rub — friction increases irritation on already-acidified skin. Use hands, not a cotton pad; hands deliver essentially 100% of the product while cotton pads absorb roughly 30-40% of it.

Required skin state: fully dry (not damp) — applying to wet skin dilutes the acid concentration unevenly and increases the risk of patchy irritation.

Wait time: exactly 10 minutes, no longer, timed with a clock or phone timer rather than guessed — this pH-dependent formula is engineered around that specific contact window.

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, 10-15 min before sunscreen if going outdoors. Hard cap rule: 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 (optional, 1-3)
4. Essence (optional)
5. Mist (optional)

12. Eye Serum/Cream
13. Moisturizer
14. Optional Sealing Layer (dry/AC only)
15. Sunscreen SPF50+ PA++++ (non-negotiable)

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

Lane strictness: 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.

Rung: water-thin gel-solution — applied directly to clean, dry skin as its own isolated step, not layered under or over other treatments, since it is rinsed off entirely before the rest of the routine begins.

Layering rule: nothing goes on before it (bare, dry skin only) and nothing goes on with it — moisturizer only follows after the full rinse.

Phase compatibility: water-phase, aqueous gel base (Xanthan Gum as the thickener) — does not interact with oil-phase products since it never coexists on skin with them.

Rest days: at least 2-3 full days between uses so the barrier can rebuild lipids stripped by the acid contact.

Overuse warning: maximum twice weekly. Exceeding this does NOT produce faster results — it produces barrier damage, and once damaged, you lose weeks of usable exfoliation time to recovery instead of gaining it.

Purge vs. reaction: PURGING (if it occurs) shows up in your usual breakout areas, stays surface-level, and resolves in 4-6 weeks. A REACTION — new areas, burning, swelling, or hives — means stop immediately rather than waiting it out.

Prerequisites: before starting this product, your routine MUST already include a consistent daily SPF habit, a working barrier moisturizer, and at least 4-6 weeks of tolerating a gentler acid (7-10% AHA or 2% BHA) without irritation. Without these foundations, this product causes more harm than benefit.

Barrier index gate: if your skin stings on moisturizer, feels tight within 30 minutes of cleansing, or shows visible flaking, your barrier is below threshold — start with Dr.Althea 147 Barrier Cream for at least 1-2 weeks first.

Rough texture: the 30% AHA blend loosens the bonds (corneodesmosomes) holding dead surface cells together, so they shed more evenly instead of building up in dull, rough patches.

Congested pores: the 2% salicylic acid is lipophilic (oil-soluble), letting it travel into the sebum-filled pore lining itself rather than just acting on the skin surface, where the AHAs mostly work.

Uneven tone/dullness: faster, more even cell turnover reduces the buildup that makes skin look grey or dull in humid, high-sebum conditions.

What this product cannot do: it cannot physically shrink pore size (pores don't have muscles to contract), cannot remove deep acne scarring or ice-pick scars (that needs in-clinic procedures), and cannot lighten your natural skin tone — any brightening effect is from clearing dulling buildup and fading post-inflammatory marks, not changing your underlying pigmentation.

1. Barrier moisturizer — Dr.Althea 147 Barrier Cream: applied immediately after rinsing to replace lipids the acid contact removes. Use PM, right after this product.

2. Gentle low-pH cleanser — COSRX Low pH Good Morning Gel Cleanser: keeps the skin surface at a compatible pH before the peel session, rather than an alkaline cleanser fighting against the acid's calibrated pH. Use PM, as the cleansing step before this product.

3. Broad-spectrum sunscreen — SKIN1004 Hyalu-Cica Water-Fit Sun Serum SPF50+ PA++++: mandatory the morning after any peel session, since freshly exfoliated skin is more UV-reactive. Use AM, every day this product is in rotation.

4. Own-brand barrier serum — The Ordinary Soothing & Barrier Support Serum: a same-brand option for recovery nights between peel sessions. Use PM, on non-peel nights only.

Pilling pairs: because this product is rinsed off before anything else is applied, it does not pill with other products directly — but layering too many rich creams immediately after rinsing, before the skin has calmed, can feel heavy. Wait 1-2 minutes post-rinse before moisturizer if this happens.

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 OR strong acne lane). If you break a rule, don't push through — reduce frequency, split AM/PM, or alternate nights. Barrier override: if moisturizer stings or skin feels tight within 30 minutes of cleansing, pause all actives and run barrier-only for 3-7 days.

× Retinoids (Retinol/Retinal/Tretinoin/Adapalene): never the same night. Use Skin Cycling (Peel night → Retinoid night → 2 recovery nights) or alternate nights entirely, with at least 48 hours between them.

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

× Other AHA/BHA products (separate serums/toners): avoid stacking a second acid product on top of this one — this formula's 32% combined acid load is already the strongest single step in most routines. Alternate days instead: this product for deep exfoliation, a gentler daily toner (if used) on the days between, never both the same night.

× Chemical exfoliants × physical scrubs/microderm tools: never combine the same day — the risk of micro-tears plus over-stripping compounds quickly.

× Benzoyl Peroxide: do not layer; BPO can further irritate already-acidified skin. Keep on separate days.

Section 15C — Scheduling Templates:

Template A (most common): AM antioxidant lane → moisturizer → SPF. PM: this Peeling Solution (peel nights only) or barrier/hydration (all other nights).

Template B — 4-Night Skin Cycling: Night 1 Exfoliation (this product) → Night 2 Retinoid → Nights 3-4 Recovery.

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.

Pre-period breakouts happen because progesterone causes the pore lining to physically swell, narrowing the opening and trapping sebum beneath — this is also why some people find the BHA fraction of this product especially helpful in the days leading into their period, if their skin can tolerate it that week.

MYTH: "If my skin doesn't visibly peel or flake, it isn't working." REALITY: "Peeling" here describes the chemical-exfoliation mechanism at a cellular level, not visible skin shedding — most users see zero visible flaking even when the product is working exactly as intended.

MYTH: "Higher acid % always means better results." REALITY: at 32% combined acid, more frequent use does not accelerate results past the twice-weekly ceiling — it only accelerates barrier damage, which then slows everything down.

MYTH: "Tingling means it's burning my skin." REALITY: mild tingling for 2-5 minutes is the expected sensory signature of an acid at this pH; true burning that doesn't settle is the signal to rinse immediately, not tingling itself.

DIY risk warning: do not attempt to "boost" this product by leaving it on longer than 10 minutes or applying it more than twice weekly to chase faster results — this is one of the most commonly reported ways people injure their barrier with this exact product.

Sugar cane burning season (Jul-Nov): PM2.5 rises during this period. Since freshly-exfoliated skin (post-peel) is more reactive to airborne irritants, consider scheduling peel nights for days with lower outdoor exposure during this window, and ensure your AM antioxidant serum is in place the next morning.

Hard water note: Mauritius tap water hardness varies by region; when rinsing this product off, hard water can leave a mild calcium-stearate film that adds to post-peel tightness — a quick hydrating toner pass after rinsing and before moisturizer can help counteract that residue.

*Evidence for Tasmanian Pepperberry and Black Carrot extract at this product's undisclosed concentrations is based on general ingredient-function literature rather than a published in-vivo trial for this exact formula.

Free Acid Value: pH of 3.50-3.70. Glycolic acid's pKa is 3.83. Using the Henderson-Hasselbalch relationship across that pH range gives an estimated 57-68% (roughly 60%) of the acid in free (active) form — calculated from these two verified numbers, not a figure the brand publishes directly. This is why the product is described as strong regardless of the headline "30%" number: a large majority of that acid is genuinely active, not buffered into an inert salt.

Full INCI list: Glycolic Acid, Aqua (Water), Aloe Barbadensis Leaf Water, Sodium Hydroxide, Daucus Carota Sativa (Carrot) Extract, Propanediol, Cocamidopropyl Dimethylamine, Salicylic Acid, Potassium Citrate, Lactic Acid, Tartaric Acid, Citric Acid, Panthenol, [--- Estimated 1% Line ---] Sodium Hyaluronate Crosspolymer, Tasmannia Lanceolata Fruit/Leaf Extract, Glycerin, Pentylene Glycol, Xanthan Gum, Polysorbate 20, Trisodium Ethylenediamine Disuccinate, Potassium Sorbate, Sodium Benzoate, Ethylhexylglycerin, 1,2-Hexanediol, Caprylyl Glycol.

*Sourced by cross-referencing two independent web searches against INCIDecoder, CosDNA, Skinsort and Sephora listings for this exact SKU; direct page access to those sites was blocked this pass, so confidence is medium-high rather than a first-party packaging read.

Preservative system: Potassium Sorbate and Sodium Benzoate (organic acid preservatives), supported by Ethylhexylglycerin, 1,2-Hexanediol and Caprylyl Glycol (multifunctional preservative-boosters).

Fragrance status: Fragrance-Free — no Parfum/Fragrance ingredient in the declared INCI.

Scent: a faint, sharp, vinegar-adjacent acidic scent from the acid blend itself, dissipating within seconds of rinsing — not a fragrance ingredient, just the natural smell of concentrated organic acids.

Intensity: 1-2 out of 5, dissipating within seconds after rinse.

EU 26 allergen screen: none detected in the declared INCI.

Alcohol disclosure: Alcohol-Free — no ethanol/Alcohol Denat. in the declared INCI.

Aspirin/salicylate sensitivity: this product contains Salicylic Acid (BHA) at 2%. If you have a diagnosed aspirin or salicylate sensitivity, patch test carefully and consider consulting a doctor before facial use, since topical salicylic acid is chemically related to the same salicylate family.

Prescription interactions: combining with prescription tretinoin, adapalene, isotretinoin, or other prescription-strength topical acids compounds irritation risk substantially — see the safety notice and Conflict Solver above.

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. *Brand states cruelty-free, but The Ordinary/DECIEM entered Mainland China retail via Sephora China in February 2025, where post-market animal testing may be required by law for certain cosmetics; cross-border e-commerce sales may be exempt.

Microplastic-Free: Yes — no known microplastic polymers detected in the declared INCI.

MFDS classification: Not applicable — The Ordinary is a Canadian brand manufactured by DECIEM in Toronto and is not MFDS-registered, unlike the Korean-registered brands elsewhere in this catalog.

Clinical evidence: the AHA/BHA exfoliation mechanism itself is well-established cosmetic chemistry, supported by decades of dermatology literature on alpha- and beta-hydroxy acids. The brand's own "comparable to a professional peel" comparison claim is a marketing statement footnoted by the brand itself rather than an independently published head-to-head clinical trial located during this research pass.

Evidence confidence: Medium for the underlying acid-exfoliation mechanism (High-confidence ingredient science); Marketing-Only* for the specific "comparable to a professional peel" positioning claim.

*Marketing-Only: this specific comparative claim is brand-stated rather than independently verified against a professional in-clinic peel in a published study located this pass.

FA safety: FA-Conditional — Polysorbate 20 is present, generally considered low-risk/non-feeding by current fungal-acne trackers, disclosed here for transparency rather than as a red flag.

Assessment: None to Low. Because this product is rinsed off completely before any other step, it doesn't sit on skin alongside other products the way a leave-on serum would, which removes most pilling risk by design.

Mitigation: the only pilling-adjacent issue reported is applying a thick moisturizer immediately onto skin that's still slightly acid-reactive right after rinsing — wait 1-2 minutes post-rinse, pat dry, then moisturize.

Colour baseline: a consistent reddish-orange from the carrot extract; a marked colour shift toward brown, or separation that won't remix with gentle shaking, suggests the formula has degraded and should be discarded rather than used.

Storage: keep away from direct sun and away from bathroom-shelf heat/humidity spikes where possible — a bedroom drawer or cabinet is more stable than a steamy shower shelf in Mauritius's climate.

Spoilage signs: off/rancid smell beyond the normal sharp acidic scent, visible separation that won't remix, or a notable colour shift. When in doubt, discard.

Patch test: apply a small amount to the inner forearm, wait 24 hours, then test behind the ear for another 24 hours, before your first full facial application — this is not optional for a product at this strength.

72-hour barrier reset: if you get an adverse reaction, 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 beyond the normal 10-minute contact window, or breathing difficulty — seek emergency care immediately for the latter.

Pregnancy alternatives (in-catalog, verified, primary + 3): Dr.Althea 147 Barrier Cream (primary) · Purito Seoul Wonder Releaf Centella Cream Unscented · Purito Seoul Wonder Releaf Centella Cream · SKIN1004 Probio-Cica Enrich Cream — none of these are acid exfoliants; they support barrier comfort only. Always confirm any active ingredient with your OB/GYN first regardless of what any product page states.

1. Leaving it on longer than 10 minutes hoping for faster results — this only increases irritation risk, not effectiveness.
2. Using it more than twice weekly.
3. Applying to damp skin instead of fully dry skin.
4. Skipping SPF the next morning.
5. Combining it the same night with a retinoid, Vitamin C, or another exfoliating acid.

Overuse threshold: more than twice weekly consistently risks a compromised barrier, visible redness, and a step backward in texture and tone rather than forward.

Volume: 30ml. Amount per use: roughly 1-1.5ml (a thin, even full-face layer, well under a full teaspoon). Approximate uses per container: roughly 20-25 sessions at the recommended thin-layer amount.

Lifespan: at the maximum recommended twice-weekly frequency, a 30ml bottle lasts roughly 10-12 weeks; at the safer once-weekly starting frequency, closer to 20-25 weeks. Using more than the correct thin layer per session shortens this without improving results.

Reorder timing: consider reordering about 2 weeks before you expect to run out, to allow for shipping time.

This product is the peak-strength exfoliation step in an otherwise simple routine — it does not need a complicated 10-step system around it, just a solid cleanse-and-barrier foundation on either side.

AM (every day): Gentle cleanser (optional) → antioxidant serum (optional) → moisturizer → SPF50+ PA++++ (mandatory).

PM (peel nights, max 2x/week): Gentle cleanse → pat fully dry → Peeling Solution, 10 minutes, timed → rinse thoroughly → barrier moisturizer.

PM (all other nights): Gentle cleanse → barrier/soothing serum → moisturizer.

If your skin is barrier-compromised right now: pause this product entirely and run the 72-Hour Barrier Reset before your first session, not after a bad reaction.

If you are in air-conditioning most of the day: your barrier moisturizer matters more, not less, on peel days — AC dries indoor air and compounds the temporary dryness from the acid session.

If you are in your luteal phase and skin feels more reactive: drop to once weekly or skip that week's session rather than pushing through.

Stock-true bundle (barrier support): this Peeling Solution + Dr.Althea 147 Barrier Cream + COSRX Low pH Good Morning Gel Cleanser + SKIN1004 Hyalu-Cica Water-Fit Sun Serum: cleanse low-pH, peel per schedule, always follow with barrier cream, always SPF the next morning.

Stock-true bundle (recovery-night option): this Peeling Solution + The Ordinary Soothing & Barrier Support Serum + Purito Seoul Wonder Releaf Centella Cream: same-brand barrier serum on non-peel nights, centella cream to seal, keeping the routine simple around the one strong step.

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

The recommendations above are based on formulation synergy with AHA 30% + BHA 2% Peeling Solution, 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 texture-and-tone benefits without professional-peel-strength intensity, several lower-intensity, leave-on options exist in Adilsons' catalog — a genuinely different trade-off (gradual daily maintenance), not a weaker version of the same thing.

Primary pick: SOME BY MI AHA-BHA-PHA 30 Days Miracle Toner — a much lower-intensity, leave-on multi-acid toner used daily.

Alternatives: NINE LESS Molecule-Clear Lactic Acid Serum (single-active 5% Lactic Acid, gentler AHA-only option) · APLB AHA BHA PHA Centella Facial Toner (multi-acid toner with added centella soothing) · APRIL SKIN Calendula 10% PHA+AHA Resurfacing Serum (PHA-led, generally the gentlest exfoliation mechanism of the three).

Thesis: Choose AHA 30% + BHA 2% Peeling Solution over the SOME BY MI AHA-BHA-PHA 30 Days Miracle Toner if you need maximum single-session acid strength delivered in one deliberate rinse-off treatment, rather than gradual daily maintenance exfoliation.

Upgrade triggers (IF/THEN):

• If you've used a 7-10% AHA daily for 6+ weeks without irritation, THEN this level of strength is a reasonable next step.
• If your skin is dehydrated-oily rather than truly oily, THEN start with the gentler daily toner first, not this.
• If your barrier is currently compromised, THEN do not upgrade yet — repair barrier first, regardless of how long you've used other acids (hard safety override).
• If you are new to any chemical exfoliation, THEN the daily toner is the correct starting point, not this peel.
• If you are breakout-prone with a tendency toward fungal-acne-type bumps, THEN this product's rinse-off design is actually gentler on that specific risk than a leave-on acid left sitting on skin all day.
• If you are currently purging from a different new active, THEN wait until that settles before adding this — two unknowns at once makes any reaction impossible to attribute.
• If your main goal is deep congestion in the T-zone rather than overall texture, THEN the BHA fraction here specifically is what the gentler daily toner likely can't match at the same depth.

Timing and lane: PM only, occupies the Exfoliation lane exclusively (see Conflict Solver above); never combine with a retinoid or Vitamin C the same night; apply to fully dry skin only.

Don't upgrade if: your barrier is below threshold (stings on moisturizer); you can't commit to consistent daily SPF; you're already running a daily acid toner and it's working fine; you're new to actives generally, regardless of skin type.

If you match 2 or more upgrade triggers above, THIS is worth choosing. If not, the alternative is sufficient and safer. Consistency beats complexity.

The Ordinary's own exfoliation range forms a natural ladder: Glycolic Acid 7% Exfoliating Toner (gentle, daily leave-on) → Mandelic Acid 10% + HA (a larger-molecule, gentler AHA still suited to more frequent use) → this Peeling Solution (peak strength, twice-weekly maximum, rinse-off only).

Honest stock note: both step-down products above are currently out of stock at Adilsons at the time of writing. Until they're back in stock, SOME BY MI AHA-BHA-PHA 30 Days Miracle Toner or the NINE LESS Molecule-Clear Lactic Acid Serum (5% Lactic Acid) serve as reasonable cross-brand stand-ins for the gentler end of the ladder.

This product's PRIMARY function is: rinse-off, high-strength chemical exfoliation. You do NOT need this if you already own another AHA product above 15% concentration or a professional-strength peel pad/solution doing the same job — running two peak-strength exfoliants creates redundant, stacked over-exfoliation risk rather than added benefit.

Inventory audit: check whether you already have an open bottle of any strong AHA or BHA exfoliant before buying a second one; PAO is typically 6-12 months once opened (confirm the exact figure on your box's PAO symbol), so buying a duplicate while one sits half-used is genuine waste.

Stacking assessment: No Benefit if you already run a comparable-strength AHA/BHA exfoliant (same mechanism, redundant); Significant Benefit if your current routine has no direct-acid exfoliation step at all and your barrier can support adding one.

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.

Note: The Ordinary is a Canadian brand manufactured by DECIEM in Toronto rather than a Korean-manufactured brand — Adilsons' standard authorized-distribution-partner sourcing statement above still applies as the store's general supply-chain disclosure, but Craver Co., Ltd specifically is a Korean distributor and is unlikely to be this brand's own import path.

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 bottles carry a batch/lot code on the carton base, often echoed on the bottle underside; The Ordinary's packaging is deliberately plain and clinical — a glossier finish, added scent, or a mismatched cap thread are common counterfeit tells reported by the community.

The Ordinary's stated positioning is "clinical formulations with integrity" — naming products by active ingredient and concentration directly, rather than marketing names, with minimal secondary packaging. It is a Canadian mass-clinical brand, not a K-beauty brand, despite being carried by this K-beauty-focused retailer alongside its Korean-formulated neighbours.

This exact product, often nicknamed the "Red Peeling Solution" for its carrot-derived tint, is one of the brand's most widely discussed products, largely because it is unusually strong for an over-the-counter, non-prescription formula.

Aggregator data (Skinsort) reports this product holding a strong average rating (approximately 4.6 out of 5 across roughly 282 ratings) — a snapshot figure, not independently reconfirmed against a live retailer page this pass.

Positive (paraphrased, platform-sourced): one reviewer described skin feeling "renewed" and noticeably softer immediately after rinsing off, with regular twice-weekly use smoothing rough texture over several weeks.

Mixed (paraphrased): several reviewers noted they saw no visible "peeling" or flaking at all despite the product name, but still reported smoother-feeling skin — a recurring point of confusion the Myth Replacement section above addresses directly.

Critical (paraphrased): some reports describe stinging beyond mild tingling on first use, particularly for people who had not built up tolerance with a gentler acid first, and a smaller number reported next-day sun sensitivity when they skipped SPF.

Direct first-hand Reddit threads were not opened during this research pass (WebFetch access to reddit.com and several ingredient-database sites was blocked by the network egress proxy this run); the above reflects web-search summaries of aggregator and retailer review data rather than a first-hand community read.

Sustainability: glass is broadly recyclable through standard glass recycling streams where available in Mauritius; the product is not currently offered in a refill format.

How long do I actually leave it on? No more than 10 minutes, timed — not "until it feels done." Rinse sooner if it burns rather than tingles.

How often can I use it? A maximum of twice weekly, and most people should start at once weekly for the first several sessions.

Is tingling normal, or should I rinse it off? Mild tingling for 2-5 minutes is the expected sensory signature of this acid blend at this pH. Genuine burning that doesn't settle, or pain, means rinse immediately.

Why doesn't my skin visibly peel like the name suggests? "Peeling" describes the chemical-exfoliation mechanism at a cellular level, not visible flaking — most users never see visible skin shedding even when the product is working as intended.

Can I use this if I'm pregnant or breastfeeding? No — see the safety notice at the top of this page for the specific reasoning, and consult your OB/GYN about alternatives regardless of what any product page states.

AHA (Alpha Hydroxy Acid)

A group of water-soluble acids (glycolic, lactic, tartaric, citric) that exfoliate the skin's surface.

BHA (Beta Hydroxy Acid)

An oil-soluble acid (salicylic acid here) that can travel inside oil-filled pores.

pKa

A chemistry value describing the pH at which an acid is exactly half active, half neutralized — used with the product's own pH to estimate how much of the acid is truly "active."

Free acid value

The percentage of an acid that is in its active (not neutralized) chemical form at a given pH.

Corneodesmosomes

The protein "glue" holding dead skin cells together; AHAs loosen these bonds to encourage shedding.

Purging

A temporary increase in breakouts in your usual problem areas as an active speeds up cell turnover, distinct from an allergic reaction.

Barrier (skin barrier)

The outermost layer of skin that keeps moisture in and irritants out; strong acids can temporarily weaken it if overused.

Fungal Acne (Malassezia) Safety

Whether a formula avoids feeding a yeast that can cause small, itchy, uniform bumps in some people.

Skin cycling

A 4-night rotation alternating exfoliation, retinoid, and recovery nights to avoid over-stacking actives.

Best for: experienced, resilient oily-to-combination skin with an already-healthy barrier and a consistent SPF habit, looking for the strongest single-step chemical exfoliation available without a clinic visit.

Key benefits: a brand-disclosed, high total acid concentration (32% combined) targeting both surface texture (AHA) and pore congestion (BHA) in one 10-minute session; a calibrated pH backed by real chemistry rather than a vague "gentle exfoliating complex"; rinse-off design that limits total contact time versus a leave-on acid.

Keep in mind: this is not suitable for pregnancy/breastfeeding, under-16 use, sensitive or compromised skin, or anyone new to chemical exfoliation — the brand's own copy is explicit that this is for experienced users only, and the twice-weekly ceiling is a hard limit, not a suggestion.

Assessment: Not Suitable / Consult Oncologist. While this formula is fragrance-free, active cancer treatment (chemotherapy, radiation, some targeted therapies) commonly leaves skin more reactive, thinner, and slower to recover than usual — exactly the conditions this product's own brand-stated caution ("not suitable for sensitive, peeling, or compromised skin") already excludes, independent of treatment status.

A professional-peel-strength acid exfoliant is generally one of the first product categories oncology-focused skincare guidance advises pausing during active treatment, given the already-compromised barrier and slower healing capacity treatment-sensitized skin typically has.

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

Quick version:

• Week 1-2 — one session only, monitor for 48 hours after.
• Week 3-4 — a second session if the first caused no lingering irritation, still no more than once weekly.
• Week 5+ — twice weekly maximum, only once tolerance is clearly established.
• If irritation occurs at any point, refer to the 72-Hour Barrier Reset above rather than pushing forward or repeating it here.

This product must be introduced as the ONLY new product in your routine. Wait 14 days before adding anything else.

Antioxidant pollution defense: Daucus Carota Sativa (carrot) extract contributes mild antioxidant support, though at an undisclosed, likely secondary concentration — this product's primary role is exfoliation, not daily pollution defense, so pair it with a dedicated AM antioxidant serum for that purpose.

Hard water interaction: since this product is fully rinsed off with tap water, Mauritius's regionally variable hard water can leave a mild calcium-stearate residue on top of the expected post-acid tightness — a brief hydrating toner pass before moisturizer helps counteract this, as noted in the Climate Fit section above.

Decision point, end of Week 2: any persistent redness or burning? YES → stay at once-every-10-14-days frequency for another 2 weeks. NO → proceed to Week 3's schedule.
