AHA 30% + BHA 2% Peeling Solution
A viral, high-strength exfoliating mask combining 30% AHA (glycolic, lactic, tartaric & citric acids) with 2% BHA (salicylic acid) to deeply resurface skin, clear congested pores, improve texture, and fade hyperpigmentation — all in a single 10-minute weekly treatment. Enriched with Tasmanian Pepperberry to reduce irritation, Hyaluronic Acid for hydration, and Black Carrot as a natural antioxidant.
✨ Texture & Feel
5-Acid Exfoliating Complex
Glycolic, lactic, tartaric, and citric acids (30% AHA) work on the skin surface while salicylic acid (2% BHA) dives deep into pores for a synergistic dual-action peel.
Tasmanian Pepperberry Anti-Irritant
Derived from Tasmannia lanceolata, this botanical extract is clinically shown to reduce the redness and discomfort typically associated with high-concentration acid formulas.
Hyaluronic Acid Crosspolymer
An advanced crosslinked form of hyaluronic acid that stays anchored in the skin's uppermost layers longer than standard HA, delivering sustained surface hydration throughout the peel.
Black Carrot Antioxidant
Daucus Carota Sativa Extract provides antioxidant protection and gives the solution its signature deep-red color — a natural indicator of its botanical origin.
Clinically-Comparable Results
The Ordinary positions this as an at-home peel designed to deliver results comparable to professional in-office chemical peels at a fraction of the cost.
Exceptional Value
At under $8 for 30 ml, this is one of the most affordable high-concentration AHA/BHA exfoliants on the market — making professional-grade exfoliation accessible to all.
🛡️ Safety & Compatibility
Contains 2% Salicylic Acid (BHA). High-dose oral salicylates are associated with fetal risk, and while topical use is generally low-absorption, most dermatologists advise avoiding leave-on or rinse-off salicylic acid formulations at concentrations above 2% during pregnancy. Consult your OB/GYN before use. The AHA portion is generally considered lower risk but always seek medical advice.
NOT fungal acne safe. Contains Polysorbate 20, an ingredient that can feed Malassezia yeast and potentially trigger or worsen fungal acne (pityrosporum folliculitis). Those prone to fungal acne should consider a Polysorbate 20-free alternative.
100% vegan formula with no animal-derived ingredients. The Ordinary and parent company Deciem are certified cruelty-free — no animal testing at any stage of production.
Contains no oils or high-comedogenic ingredients. The formula is entirely oil-free and silicone-free, making it non-pore-clogging and suitable for acne-prone skin when fungal acne is not a concern.
AHAs significantly increase UV sensitivity. Daily SPF 30+ is mandatory when using this product. Limit sun exposure for at least one week after each application. The brand recommends PM use only to reduce risk.
For experienced acid users only. At 32% total acid concentration, this is one of the strongest over-the-counter chemical exfoliants available. Avoid if you have rosacea, eczema, active breakouts, compromised barrier, or are new to chemical exfoliation.
Do NOT use on the same night as retinol, retinoids, vitamin C, niacinamide at high concentrations, or other acids. The combination can severely compromise the skin barrier and cause chemical burns. Alternate evenings at minimum.
Contains absolutely no added fragrance, perfume, or essential oils — making it suitable for fragrance-sensitive individuals as long as the high acid concentration is tolerated.
🔬 Ingredient Breakdown
⚗️ Glycolic Acid ~20% Proven
The star AHA in this formula and the most extensively researched alpha hydroxy acid in dermatology. Derived from sugarcane, glycolic acid has the smallest molecular weight of all AHAs, allowing it to penetrate deeper into the skin than lactic or tartaric acid. It breaks down the bonds holding dead skin cells together, accelerates cell turnover, and — uniquely among AHAs — stimulates collagen synthesis with long-term use.
- Mechanism: Disrupts corneodesmosomes (the "glue" holding dead cells), promoting desquamation and revealing fresher skin below.
- Collagen: Studies show glycolic acid at concentrations above 8% increases Type I and Type III collagen mRNA expression in fibroblasts.
- Optimal pH: Works most effectively between pH 3.0–4.5 — the pH range this formula is formulated within.
- Concentration: Estimated at ~18–22% of the 30% AHA total based on ingredient list position.
🧪 Salicylic Acid (BHA) 2% Proven
The sole BHA in the formula at the FDA-recognized maximum OTC acne treatment concentration of 2%. Unlike AHAs which are water-soluble and work on the skin's surface, salicylic acid is oil-soluble, allowing it to penetrate through sebum and deep into pores where it dissolves blackheads, whiteheads, and trapped debris. It also has notable anti-inflammatory properties similar to aspirin, helping to calm active blemishes while exfoliating.
- Oil-solubility: Dissolves through sebum to reach pore walls — making it uniquely effective for comedonal acne and blackheads.
- Anti-inflammatory: Structurally similar to acetylsalicylic acid, it inhibits COX enzymes to reduce redness and swelling around blemishes.
- FDA Status: Recognized as a safe and effective OTC acne treatment ingredient at 0.5–2%.
🍋 Lactic Acid ~5–8% Proven
A gentler AHA derived from fermented milk (or synthetically produced for vegan formulas). Lactic acid has a larger molecular size than glycolic acid, meaning it penetrates more slowly and is less likely to cause irritation. Notably, lactic acid functions as a dual-action ingredient: it exfoliates AND acts as a humectant by binding water molecules in the skin — making it the most hydrating of all AHAs. It is also a component of the skin's Natural Moisturizing Factor (NMF).
- Humectant function: Draws moisture into the stratum corneum, counteracting the drying effects of exfoliation.
- NMF component: Naturally found in healthy skin as sodium lactate, making it particularly compatible with skin biology.
- Hyperpigmentation: Studies show lactic acid at 12% reduces melasma and post-inflammatory hyperpigmentation with consistent use.
🍇 Tartaric Acid ~2–4% Promising
A naturally derived AHA found in grapes and wine. Tartaric acid has a larger molecular weight than glycolic or lactic acid, contributing gentler surface-level exfoliation. In this formula, it primarily serves as a pH stabilizer alongside citric acid, helping to maintain the formula at its optimal low pH for acid activity. It also contributes antioxidant properties derived from its grape origin.
- pH buffering: Helps maintain the formula's low pH of ~3.5, essential for AHA activity.
- Antioxidant: Exhibits free radical scavenging activity, offering mild photoprotective support.
🍊 Citric Acid ~1–3% Proven
Derived from citrus fruits, citric acid is the mildest AHA in this formula. At low concentrations, it primarily functions as a pH adjuster to keep the formula in the ideal acid range. At higher concentrations (above 10%), research shows it can improve sun-damaged skin, increase skin thickness, and boost glycosaminoglycans (including hyaluronic acid) production. In this formula, it contributes both to exfoliation and pH regulation.
- Chelating agent: Binds metal ions that can degrade formula stability, extending shelf life.
- Skin thickening: At higher concentrations, shown to increase collagen and glycosaminoglycan content in skin.
🌿 Tasmannia Lanceolata Fruit/Leaf Extract trace Promising
Tasmanian Pepperberry extract is the formula's signature anti-irritant. This indigenous Australian botanical is rich in polygodial and other drimane sesquiterpenes with documented anti-inflammatory, anti-allergic, and antimicrobial activity. The Ordinary specifically uses it to reduce the stinging, redness, and discomfort users typically experience with high-concentration acid formulas.
- Anti-irritant: Polygodial compounds in the extract suppress TRPV1 receptors responsible for the burning sensation acids produce.
- Natural colorant: Responsible for contributing to the formula's characteristic deep red/burgundy hue alongside black carrot.
💧 Sodium Hyaluronate Crosspolymer trace Proven
An advanced, crosslinked form of sodium hyaluronate (hyaluronic acid salt) that creates a polymer network on the skin's surface. Unlike standard hyaluronic acid which can evaporate quickly, the crosspolymer structure allows it to remain on the skin longer, providing sustained hydration that helps offset the drying effect of strong acids. It also forms a temporary protective film that improves comfort during application.
- Film-forming: Creates a breathable moisture-retaining layer over the acid-treated skin surface.
- Extended delivery: Crosspolymer structure delays dispersal compared to standard HA, increasing contact time and hydration benefit.
25 ingredients
Glycolic Acid, Aqua (Water), Aloe Barbadensis Leaf Water, Sodium Hydroxide, Daucus Carota Sativa Extract (Black Carrot), Propanediol, Cocamidopropyl Dimethylamine, Salicylic Acid, Potassium Citrate, Lactic Acid, Tartaric Acid, Citric Acid, Panthenol (Pro-Vitamin B5), Sodium Hyaluronate Crosspolymer, Tasmannia Lanceolata Fruit/Leaf Extract (Tasmanian Pepperberry), Glycerin, Pentylene Glycol, Xanthan Gum, Polysorbate 20, Trisodium Ethylenediamine Disuccinate, 1,2-Hexanediol, Caprylyl Glycol, Ethylhexylglycerin, Potassium Sorbate, Sodium Benzoate
🔄 Where It Fits in Your Routine
Use PM only, 1–2x per week maximum. Apply to completely dry skin after cleansing — water dilutes acids and reduces effectiveness. Rinse off thoroughly after 10 minutes. Follow immediately with a hydrating serum and moisturizer. Never layer over other actives on the same night.
📝 How to Use
Cleanse & Dry Thoroughly
Wash your face with a gentle, sulfate-free cleanser. Pat skin completely dry with a clean towel — wait at least 5 minutes. Applying acids to damp skin dilutes the formula and can cause uneven, patchy exfoliation.
Apply Evenly to Face & Neck
Using fingertips, apply a thin, even layer across the entire face and neck area. Avoid the delicate eye area, lips, and any broken, irritated, or sunburned skin. The solution will appear deep red — this is normal and is from the black carrot extract.
Leave On for Up to 10 Minutes
A light tingling or warming sensation is normal. Do NOT leave on longer than 10 minutes. If you experience significant burning, stinging, or discomfort before 10 minutes, rinse off immediately. New users should start with 3–5 minutes and gradually increase.
Rinse Thoroughly with Lukewarm Water
Rinse with lukewarm water for at least 30 seconds to ensure all acid residue is fully removed. Avoid hot water which can irritate freshly exfoliated skin. Pat dry gently.
Apply Hydrating Serum + Moisturizer
Immediately follow with a calming, hydrating serum (hyaluronic acid, centella, or ceramides work well). Then seal with a rich moisturizer. Freshly exfoliated skin is primed to absorb the next products more effectively.
Apply SPF Next Morning (Non-Negotiable)
AHAs significantly increase UV sensitivity for up to 7 days after use. Apply a broad-spectrum SPF 30+ every single morning without exception when using this product. Skipping sunscreen makes this product unsafe to use.
👤 Who Is It For?
✅ Perfect for you if:
- You have experience with chemical exfoliants and want to level up
- You're dealing with blackheads, whiteheads, or congested pores
- You want to fade post-acne dark spots (PIH) or hyperpigmentation
- Dull, rough, or uneven skin texture is your main concern
- You want professional-level exfoliation on a budget
- You have oily or combination skin that tolerates acids well
- You're consistent with daily SPF use
❌ Consider alternatives if:
- You are pregnant or breastfeeding (due to 2% salicylic acid)
- You are a beginner to chemical exfoliation
- You have sensitive, reactive, or rosacea-prone skin
- You have an active eczema flare or compromised skin barrier
- You have fungal acne (Polysorbate 20 present)
- You cannot commit to daily sunscreen use
- You have open wounds, active cold sores, or sunburned skin
🎯 Skin Type Compatibility
Oil-free formula works brilliantly on oily skin — the BHA cuts through sebum to decongest pores, while AHAs resurface without adding shine. A top pick for oily-acne-prone types.
Dual AHA/BHA action makes this ideal for combination skin — AHAs address surface texture and dry patches, while BHA targets the oily T-zone and enlarged pores simultaneously.
Works well for normal skin types looking to maintain glow, prevent congestion, and keep texture refined. Start with once-weekly application and monitor skin response.
The high acid concentration can exacerbate dryness and lead to over-exfoliation if barrier is already compromised. Once weekly max, followed by a very rich moisturizer. Build up slowly.
Not recommended. At 32% combined acid concentration, this formula is too aggressive for sensitive, rosacea-prone, or reactive skin. A gentler AHA like 5% glycolic or a PHA would be more appropriate.
A powerhouse for acne-prone types: BHA clears pore congestion that leads to breakouts, AHAs fade post-acne marks, and the oil-free formula won't clog pores. Note: not for fungal acne (contains Polysorbate 20).
📈 Results Timeline
Immediate Glow & Smoother Texture
Most users notice visibly brighter, smoother skin within 24 hours of the first application. The high concentration of AHAs provides rapid exfoliation that reveals a more radiant complexion almost immediately. Slight temporary redness or tingling during application is normal and typically subsides within 30–60 minutes post-rinse.
~85% noticedImproved Skin Texture & Reduced Congestion
With consistent once or twice weekly use, rough texture and skin congestion (blackheads, bumps) begin to improve noticeably. Pores appear smaller as BHA clears buildup. Skin feels significantly smoother to the touch and foundation applies more evenly.
~78% noticedFading of Dark Spots & Hyperpigmentation
Post-acne marks (PIH), sun spots, and uneven skin tone begin to visibly lighten as accelerated cell turnover brings fresher skin to the surface. This phase is when most users report the most dramatic transformation in their overall complexion clarity and evenness.
~72% noticedRefined Pores, Reduced Fine Lines & Long-Term Glow
Continued stimulation of collagen production from glycolic acid begins to reduce the appearance of fine lines and superficial wrinkles. Pores appear consistently refined. Skin tone is significantly more even. Many users report needing less makeup as the underlying skin quality improves dramatically.

💰 Budget-Friendly Alternatives (Dupes)
Nearly identical formula concept — 30% AHA and BHA in a red-tinted solution. Uses glycolic, lactic, and salicylic acids at similar concentrations. Fragrance-free, vegan. The main difference: slightly different botanical support ingredients and available in a larger 75 ml size for better value. Ideal for those who love The Ordinary's formula but want more product per dollar.
A gentler alternative featuring 7% glycolic acid (AHA only, no BHA) in a fermented botanical base. Ideal for those who want surface exfoliation without the intensity of The Ordinary's peel. Significantly less irritating, suitable for beginners, but less effective for pore congestion (no BHA component) and less dramatic texture improvement per use.
A bestselling leave-on toning formula with 5% glycolic acid — far lower concentration than The Ordinary's peel but suitable for daily use and sensitive skin. No BHA component. Works more gradually but with far less irritation risk. Great entry-level option for those not yet ready for high-strength chemical peels. Available in 100 ml and 250 ml sizes.

❓ Frequently Asked Questions
This product requires caution during pregnancy and breastfeeding due to the 2% salicylic acid (BHA) it contains. While topical salicylic acid has lower systemic absorption than oral doses, most dermatologists and OB/GYNs advise avoiding high-concentration salicylic acid products during pregnancy as a precaution. The AHA components (glycolic, lactic, tartaric, citric acids) are generally considered lower risk topically but are still not fully cleared for use during pregnancy at such high concentrations. Always consult your OB/GYN or dermatologist before using any exfoliating acid product during pregnancy or while breastfeeding.
No — this product is NOT considered fungal acne (pityrosporum folliculitis / malassezia) safe. It contains Polysorbate 20, an emulsifier that has been identified as a potential trigger for Malassezia yeast overgrowth. Polysorbate 20 can feed the yeast responsible for fungal acne. If you are prone to fungal acne, look for AHA/BHA alternatives that are specifically formulated without Polysorbate esters. Paula's Choice 2% BHA Liquid is one popular alternative that is generally considered fungal acne safe.
No — do not use this product on the same evening as retinol, retinoids (tretinoin, adapalene), vitamin C serums, niacinamide at high concentrations, or any other exfoliating acids. The combination of multiple strong actives in one session can severely compromise your skin barrier, cause chemical burns, intense irritation, and long-term sensitivity. Reserve the Peeling Solution for its own dedicated evening (maximum twice per week). On alternating evenings you can use retinol or vitamin C. Always listen to your skin — if you experience unusual irritation or burning, reduce frequency or discontinue use.
This product is best suited for oily, combination, and acne-prone skin types with prior experience using chemical exfoliants. The oil-free formula and BHA component make it particularly effective for those dealing with congested pores, blackheads, and excess sebum. It is moderate-to-good for normal skin when used carefully. It is not recommended for dry skin with a compromised barrier, sensitive or reactive skin, rosacea-prone skin, or anyone new to chemical exfoliation. Beginners should start with a much lower concentration AHA (such as 5–10% glycolic acid) before progressing to this level of acid intensity.
Most users notice an immediate glow and improved skin smoothness within 24 hours of the first use. After 2–4 weeks of consistent once or twice weekly use, visible improvements in skin texture, pore size, and congestion are typically apparent. Fading of dark spots, hyperpigmentation, and post-acne marks generally begins at 4–8 weeks and becomes more dramatic at the 2–3 month mark. Fine lines and deeper skin quality improvements from collagen stimulation take 2–3+ months of consistent use to become visible. Individual results vary based on skin type, starting condition, and consistency of use.
This is a rinse-off treatment used after cleansing on completely dry skin. Apply it as the first active step in your PM routine — after cleansing but before any serums, moisturizers, or other treatments. Leave on for up to 10 minutes, then rinse thoroughly with lukewarm water. After rinsing, proceed with your hydrating serum and moisturizer. Never apply it over other skincare products. Use this product exclusively in your evening routine (PM only) to reduce sun exposure risk, and always apply SPF the following morning.
No — this product has a comedogenic rating of 0/5. The formula is entirely oil-free, silicone-free, and contains no known pore-clogging ingredients. In fact, the 2% BHA (salicylic acid) in the formula actively works to clear pore congestion by dissolving sebum buildup inside pores. This makes the Peeling Solution one of the most anti-comedogenic exfoliating treatments available. Note that "non-comedogenic" does not mean it is appropriate for all acne types — if you have fungal acne, the Polysorbate 20 content may be a concern (see FAQ above).
The Period After Opening (PAO) for this product is 12 months. Once opened, use within 12 months for best efficacy and safety. The 30 ml bottle typically lasts 6–12 weeks when used correctly (1–2 times per week), so most users will well within the PAO before it expires. Store at room temperature away from direct sunlight. Discard if the formula develops an unusual odor or changes color dramatically. The natural color variation due to the botanical Black Carrot extract is normal and does not indicate spoilage.
Verdict: The Ordinary AHA 30% + BHA 2% Peeling Solution is a genuine game-changer for its price point. At under $8, it delivers a level of chemical exfoliation that typically costs 10–15x more in professional or prestige skincare. The 5-acid complex at 32% total concentration produces rapid, visible results on texture, glow, dark spots, and pore congestion that are hard to match in the drugstore or even mid-range skincare space. The inclusion of Tasmanian Pepperberry as an anti-irritant, crosspolymer hyaluronic acid, and Pro-Vitamin B5 shows thoughtful formulation beyond just stacking acids. The caveats are real: it is not for beginners, not safe for pregnancy, not fungal acne safe, and must be paired with strict SPF discipline. But for experienced acid users — particularly those with oily, combination, or acne-prone skin — this is one of the most effective and accessible chemical exfoliants ever made.

🎯 Skin Type Compatibility
Oil-free formula works brilliantly on oily skin — the BHA cuts through sebum to decongest pores, while AHAs resurface without adding shine. A top pick for oily-acne-prone types.
Dual AHA/BHA action makes this ideal for combination skin — AHAs address surface texture and dry patches, while BHA targets the oily T-zone and enlarged pores simultaneously.
Works well for normal skin types looking to maintain glow, prevent congestion, and keep texture refined. Start with once-weekly application and monitor skin response.
The high acid concentration can exacerbate dryness and lead to over-exfoliation if barrier is already compromised. Once weekly max, followed by a very rich moisturizer. Build up slowly.
Not recommended. At 32% combined acid concentration, this formula is too aggressive for sensitive, rosacea-prone, or reactive skin. A gentler AHA like 5% glycolic or a PHA would be more appropriate.
A powerhouse for acne-prone types: BHA clears pore congestion that leads to breakouts, AHAs fade post-acne marks, and the oil-free formula won't clog pores. Note: not for fungal acne (contains Polysorbate 20).
📈 Results Timeline
Immediate Glow & Smoother Texture
Most users notice visibly brighter, smoother skin within 24 hours of the first application. The high concentration of AHAs provides rapid exfoliation that reveals a more radiant complexion almost immediately. Slight temporary redness or tingling during application is normal and typically subsides within 30–60 minutes post-rinse.
~85% noticedImproved Skin Texture & Reduced Congestion
With consistent once or twice weekly use, rough texture and skin congestion (blackheads, bumps) begin to improve noticeably. Pores appear smaller as BHA clears buildup. Skin feels significantly smoother to the touch and foundation applies more evenly.
~78% noticedFading of Dark Spots & Hyperpigmentation
Post-acne marks (PIH), sun spots, and uneven skin tone begin to visibly lighten as accelerated cell turnover brings fresher skin to the surface. This phase is when most users report the most dramatic transformation in their overall complexion clarity and evenness.
~72% noticedRefined Pores, Reduced Fine Lines & Long-Term Glow
Continued stimulation of collagen production from glycolic acid begins to reduce the appearance of fine lines and superficial wrinkles. Pores appear consistently refined. Skin tone is significantly more even. Many users report needing less makeup as the underlying skin quality improves dramatically.

💰 Budget-Friendly Alternatives (Dupes)
Nearly identical formula concept — 30% AHA and BHA in a red-tinted solution. Uses glycolic, lactic, and salicylic acids at similar concentrations. Fragrance-free, vegan. The main difference: slightly different botanical support ingredients and available in a larger 75 ml size for better value. Ideal for those who love The Ordinary's formula but want more product per dollar.
A gentler alternative featuring 7% glycolic acid (AHA only, no BHA) in a fermented botanical base. Ideal for those who want surface exfoliation without the intensity of The Ordinary's peel.

❓ Frequently Asked Questions
This product requires caution during pregnancy and breastfeeding due to the 2% salicylic acid (BHA) it contains. While topical salicylic acid has lower systemic absorption than oral doses, most dermatologists and OB/GYNs advise avoiding high-concentration salicylic acid products during pregnancy as a precaution. The AHA components (glycolic, lactic, tartaric, citric acids) are generally considered lower risk topically but are still not fully cleared for use during pregnancy at such high concentrations. Always consult your OB/GYN or dermatologist before using any exfoliating acid product during pregnancy or while breastfeeding.
No — this product is NOT considered fungal acne (pityrosporum folliculitis / malassezia) safe. It contains Polysorbate 20, an emulsifier that has been identified as a potential trigger for Malassezia yeast overgrowth. Polysorbate 20 can feed the yeast responsible for fungal acne. If you are prone to fungal acne, look for AHA/BHA alternatives that are specifically formulated without Polysorbate esters. Paula's Choice 2% BHA Liquid is one popular alternative that is generally considered fungal acne safe.
No — do not use this product on the same evening as retinol, retinoids (tretinoin, adapalene), vitamin C serums, niacinamide at high concentrations, or any other exfoliating acids. The combination of multiple strong actives in one session can severely compromise your skin barrier, cause chemical burns, intense irritation, and long-term sensitivity. Reserve the Peeling Solution for its own dedicated evening (maximum twice per week). On alternating evenings you can use retinol or vitamin C. Always listen to your skin — if you experience unusual irritation or burning, reduce frequency or discontinue use.
This product is best suited for oily, combination, and acne-prone skin types with prior experience using chemical exfoliants. The oil-free formula and BHA component make it particularly effective for those dealing with congested pores, blackheads, and excess sebum. It is moderate-to-good for normal skin when used carefully. It is not recommended for dry skin with a compromised barrier, sensitive or reactive skin, rosacea-prone skin, or anyone new to chemical exfoliation. Beginners should start with a much lower concentration AHA (such as 5–10% glycolic acid) before progressing to this level of acid intensity.
Most users notice an immediate glow and improved skin smoothness within 24 hours of the first use. After 2–4 weeks of consistent once or twice weekly use, visible improvements in skin texture, pore size, and congestion are typically apparent. Fading of dark spots, hyperpigmentation, and post-acne marks generally begins at 4–8 weeks and becomes more dramatic at the 2–3 month mark. Fine lines and deeper skin quality improvements from collagen stimulation take 2–3+ months of consistent use to become visible. Individual results vary based on skin type, starting condition, and consistency of use.
This is a rinse-off treatment used after cleansing on completely dry skin. Apply it as the first active step in your PM routine — after cleansing but before any serums, moisturizers, or other treatments. Leave on for up to 10 minutes, then rinse thoroughly with lukewarm water. After rinsing, proceed with your hydrating serum and moisturizer. Never apply it over other skincare products. Use this product exclusively in your evening routine (PM only) to reduce sun exposure risk, and always apply SPF the following morning.
No — this product has a comedogenic rating of 0/5. The formula is entirely oil-free, silicone-free, and contains no known pore-clogging ingredients. In fact, the 2% BHA (salicylic acid) in the formula actively works to clear pore congestion by dissolving sebum buildup inside pores. This makes the Peeling Solution one of the most anti-comedogenic exfoliating treatments available. Note that "non-comedogenic" does not mean it is appropriate for all acne types — if you have fungal acne, the Polysorbate 20 content may be a concern (see FAQ above).
The Period After Opening (PAO) for this product is 12 months. Once opened, use within 12 months for best efficacy and safety. The 30 ml bottle typically lasts 6–12 weeks when used correctly (1–2 times per week), so most users will well within the PAO before it expires. Store at room temperature away from direct sunlight. Discard if the formula develops an unusual odor or changes color dramatically. The natural color variation due to the botanical Black Carrot extract is normal and does not indicate spoilage.
Verdict: The Ordinary AHA 30% + BHA 2% Peeling Solution is a genuine game-changer for its price point. At under $8, it delivers a level of chemical exfoliation that typically costs 10–15x more in professional or prestige skincare. The 5-acid complex at 32% total concentration produces rapid, visible results on texture, glow, dark spots, and pore congestion that are hard to match in the drugstore or even mid-range skincare space. The inclusion of Tasmanian Pepperberry as an anti-irritant, crosspolymer hyaluronic acid, and Pro-Vitamin B5 shows thoughtful formulation beyond just stacking acids. The caveats are real: it is not for beginners, not safe for pregnancy, not fungal acne safe, and must be paired with strict SPF discipline. But for experienced acid users — particularly those with oily, combination, or acne-prone skin — this is one of the most effective and accessible chemical exfoliants ever made.

Description
A viral, high-strength exfoliating mask combining 30% AHA (glycolic, lactic, tartaric & citric acids) with 2% BHA (salicylic acid) to deeply resurface skin, clear congested pores, improve texture, and fade hyperpigmentation — all in a single 10-minute weekly treatment. Enriched with Tasmanian Pepperberry to reduce irritation, Hyaluronic Acid for hydration, and Black Carrot as a natural antioxidant.
✨ Texture & Feel
5-Acid Exfoliating Complex
Glycolic, lactic, tartaric, and citric acids (30% AHA) work on the skin surface while salicylic acid (2% BHA) dives deep into pores for a synergistic dual-action peel.
Tasmanian Pepperberry Anti-Irritant
Derived from Tasmannia lanceolata, this botanical extract is clinically shown to reduce the redness and discomfort typically associated with high-concentration acid formulas.
Hyaluronic Acid Crosspolymer
An advanced crosslinked form of hyaluronic acid that stays anchored in the skin's uppermost layers longer than standard HA, delivering sustained surface hydration throughout the peel.
Black Carrot Antioxidant
Daucus Carota Sativa Extract provides antioxidant protection and gives the solution its signature deep-red color — a natural indicator of its botanical origin.
Clinically-Comparable Results
The Ordinary positions this as an at-home peel designed to deliver results comparable to professional in-office chemical peels at a fraction of the cost.
Exceptional Value
At under $8 for 30 ml, this is one of the most affordable high-concentration AHA/BHA exfoliants on the market — making professional-grade exfoliation accessible to all.
🛡️ Safety & Compatibility
Contains 2% Salicylic Acid (BHA). High-dose oral salicylates are associated with fetal risk, and while topical use is generally low-absorption, most dermatologists advise avoiding leave-on or rinse-off salicylic acid formulations at concentrations above 2% during pregnancy. Consult your OB/GYN before use. The AHA portion is generally considered lower risk but always seek medical advice.
NOT fungal acne safe. Contains Polysorbate 20, an ingredient that can feed Malassezia yeast and potentially trigger or worsen fungal acne (pityrosporum folliculitis). Those prone to fungal acne should consider a Polysorbate 20-free alternative.
100% vegan formula with no animal-derived ingredients. The Ordinary and parent company Deciem are certified cruelty-free — no animal testing at any stage of production.
Contains no oils or high-comedogenic ingredients. The formula is entirely oil-free and silicone-free, making it non-pore-clogging and suitable for acne-prone skin when fungal acne is not a concern.
AHAs significantly increase UV sensitivity. Daily SPF 30+ is mandatory when using this product. Limit sun exposure for at least one week after each application. The brand recommends PM use only to reduce risk.
For experienced acid users only. At 32% total acid concentration, this is one of the strongest over-the-counter chemical exfoliants available. Avoid if you have rosacea, eczema, active breakouts, compromised barrier, or are new to chemical exfoliation.
Do NOT use on the same night as retinol, retinoids, vitamin C, niacinamide at high concentrations, or other acids. The combination can severely compromise the skin barrier and cause chemical burns. Alternate evenings at minimum.
Contains absolutely no added fragrance, perfume, or essential oils — making it suitable for fragrance-sensitive individuals as long as the high acid concentration is tolerated.
🔬 Ingredient Breakdown
⚗️ Glycolic Acid ~20% Proven
The star AHA in this formula and the most extensively researched alpha hydroxy acid in dermatology. Derived from sugarcane, glycolic acid has the smallest molecular weight of all AHAs, allowing it to penetrate deeper into the skin than lactic or tartaric acid. It breaks down the bonds holding dead skin cells together, accelerates cell turnover, and — uniquely among AHAs — stimulates collagen synthesis with long-term use.
- Mechanism: Disrupts corneodesmosomes (the "glue" holding dead cells), promoting desquamation and revealing fresher skin below.
- Collagen: Studies show glycolic acid at concentrations above 8% increases Type I and Type III collagen mRNA expression in fibroblasts.
- Optimal pH: Works most effectively between pH 3.0–4.5 — the pH range this formula is formulated within.
- Concentration: Estimated at ~18–22% of the 30% AHA total based on ingredient list position.
🧪 Salicylic Acid (BHA) 2% Proven
The sole BHA in the formula at the FDA-recognized maximum OTC acne treatment concentration of 2%. Unlike AHAs which are water-soluble and work on the skin's surface, salicylic acid is oil-soluble, allowing it to penetrate through sebum and deep into pores where it dissolves blackheads, whiteheads, and trapped debris. It also has notable anti-inflammatory properties similar to aspirin, helping to calm active blemishes while exfoliating.
- Oil-solubility: Dissolves through sebum to reach pore walls — making it uniquely effective for comedonal acne and blackheads.
- Anti-inflammatory: Structurally similar to acetylsalicylic acid, it inhibits COX enzymes to reduce redness and swelling around blemishes.
- FDA Status: Recognized as a safe and effective OTC acne treatment ingredient at 0.5–2%.
🍋 Lactic Acid ~5–8% Proven
A gentler AHA derived from fermented milk (or synthetically produced for vegan formulas). Lactic acid has a larger molecular size than glycolic acid, meaning it penetrates more slowly and is less likely to cause irritation. Notably, lactic acid functions as a dual-action ingredient: it exfoliates AND acts as a humectant by binding water molecules in the skin — making it the most hydrating of all AHAs. It is also a component of the skin's Natural Moisturizing Factor (NMF).
- Humectant function: Draws moisture into the stratum corneum, counteracting the drying effects of exfoliation.
- NMF component: Naturally found in healthy skin as sodium lactate, making it particularly compatible with skin biology.
- Hyperpigmentation: Studies show lactic acid at 12% reduces melasma and post-inflammatory hyperpigmentation with consistent use.
🍇 Tartaric Acid ~2–4% Promising
A naturally derived AHA found in grapes and wine. Tartaric acid has a larger molecular weight than glycolic or lactic acid, contributing gentler surface-level exfoliation. In this formula, it primarily serves as a pH stabilizer alongside citric acid, helping to maintain the formula at its optimal low pH for acid activity. It also contributes antioxidant properties derived from its grape origin.
- pH buffering: Helps maintain the formula's low pH of ~3.5, essential for AHA activity.
- Antioxidant: Exhibits free radical scavenging activity, offering mild photoprotective support.
🍊 Citric Acid ~1–3% Proven
Derived from citrus fruits, citric acid is the mildest AHA in this formula. At low concentrations, it primarily functions as a pH adjuster to keep the formula in the ideal acid range. At higher concentrations (above 10%), research shows it can improve sun-damaged skin, increase skin thickness, and boost glycosaminoglycans (including hyaluronic acid) production. In this formula, it contributes both to exfoliation and pH regulation.
- Chelating agent: Binds metal ions that can degrade formula stability, extending shelf life.
- Skin thickening: At higher concentrations, shown to increase collagen and glycosaminoglycan content in skin.
🌿 Tasmannia Lanceolata Fruit/Leaf Extract trace Promising
Tasmanian Pepperberry extract is the formula's signature anti-irritant. This indigenous Australian botanical is rich in polygodial and other drimane sesquiterpenes with documented anti-inflammatory, anti-allergic, and antimicrobial activity. The Ordinary specifically uses it to reduce the stinging, redness, and discomfort users typically experience with high-concentration acid formulas.
- Anti-irritant: Polygodial compounds in the extract suppress TRPV1 receptors responsible for the burning sensation acids produce.
- Natural colorant: Responsible for contributing to the formula's characteristic deep red/burgundy hue alongside black carrot.
💧 Sodium Hyaluronate Crosspolymer trace Proven
An advanced, crosslinked form of sodium hyaluronate (hyaluronic acid salt) that creates a polymer network on the skin's surface. Unlike standard hyaluronic acid which can evaporate quickly, the crosspolymer structure allows it to remain on the skin longer, providing sustained hydration that helps offset the drying effect of strong acids. It also forms a temporary protective film that improves comfort during application.
- Film-forming: Creates a breathable moisture-retaining layer over the acid-treated skin surface.
- Extended delivery: Crosspolymer structure delays dispersal compared to standard HA, increasing contact time and hydration benefit.

🔄 Where It Fits in Your Routine
Use PM only, 1–2x per week maximum. Apply to completely dry skin after cleansing — water dilutes acids and reduces effectiveness. Rinse off thoroughly after 10 minutes. Follow immediately with a hydrating serum and moisturizer. Never layer over other actives on the same night.
📝 How to Use
Cleanse & Dry Thoroughly
Wash your face with a gentle, sulfate-free cleanser. Pat skin completely dry with a clean towel — wait at least 5 minutes. Applying acids to damp skin dilutes the formula and can cause uneven, patchy exfoliation.
Apply Evenly to Face & Neck
Using fingertips, apply a thin, even layer across the entire face and neck area. Avoid the delicate eye area, lips, and any broken, irritated, or sunburned skin. The solution will appear deep red — this is normal and is from the black carrot extract.
Leave On for Up to 10 Minutes
A light tingling or warming sensation is normal. Do NOT leave on longer than 10 minutes. If you experience significant burning, stinging, or discomfort before 10 minutes, rinse off immediately. New users should start with 3–5 minutes and gradually increase.
Rinse Thoroughly with Lukewarm Water
Rinse with lukewarm water for at least 30 seconds to ensure all acid residue is fully removed. Avoid hot water which can irritate freshly exfoliated skin. Pat dry gently.
Apply Hydrating Serum + Moisturizer
Immediately follow with a calming, hydrating serum (hyaluronic acid, centella, or ceramides work well). Then seal with a rich moisturizer. Freshly exfoliated skin is primed to absorb the next products more effectively.
Apply SPF Next Morning (Non-Negotiable)
AHAs significantly increase UV sensitivity for up to 7 days after use. Apply a broad-spectrum SPF 30+ every single morning without exception when using this product. Skipping sunscreen makes this product unsafe to use.
