COSRX 35 Peel is a Korean multi-acid job alternative to The Ordinary, not the same formula.
Looking for 더 오디너리 AHA 30% BHA 2% 한국 대체? The Ordinary AHA 30% + BHA 2% Peeling Solution and COSRX The AHA BHA PHA LHA 35 Peel occupy a similar high-strength, rinse-off exfoliation step. Both official pages set a 10-minute maximum, but their acid disclosures, routine frequency, supporting formula and price context differ. That is a job-level comparison—not a formula dupe or equal-strength claim.
Why this exact pair is worth answering
Public replacement discussions create a narrow query shape around this pair: one recent Korean-skincare thread asks for a Korean alternative and co-mentions The Ordinary peel with COSRX 35 Peel, while an availability discussion describes COSRX as an interim purchase after a shopper looked for The Ordinary AHA/BHA. That supports testing 더 오디너리 필링 솔루션 COSRX 35 대체 and The Ordinary AHA 30% BHA 2% Korean alternative. It does not establish search volume, ranking, product equivalence, safety, efficacy or sales.
An adjacent exfoliator thread asks for an alternative to The Ordinary AHA 30% + BHA 2% and names another product. COSRX is selected here because the first two public surfaces form a specific original-product/alternative pair rather than a generic “best acid” list.
What The Ordinary AHA 30% + BHA 2% actually publishes
| Product | AHA 30% + BHA 2% Peeling Solution |
|---|---|
| Routine job | Rinse-off acid exfoliation treatment applied to clean, dry skin |
| Format and size | Red peeling solution; 30 ml on the checked official US page |
| Published formula signal | The brand describes five exfoliating acids and 32% total; the page discloses a pH of 3.50–3.70 |
| Directions checked | Use once or twice weekly in the evening, leave on for no more than 10 minutes, then rinse; patch test first |
| US price snapshot | US$9.50 displayed on the checked official page; price and market can change |
| Label boundary | The official page limits the product to experienced acid users and warns against sensitive, peeling or compromised skin |
The Ordinary's 32% is a brand total for the published acid system, not a promise that every acid contributes equally or that another brand's headline percentage can be ranked beside it. The page also notes that ingredient lists can vary by time and region, so the package and current product page remain the final check.

What COSRX The AHA BHA PHA LHA 35 Peel currently publishes
| Product | The AHA BHA PHA LHA 35 Peel |
|---|---|
| Routine job | Gel-like, rinse-off multi-acid peel used in the evening on clean, dry skin |
| Format and size | Gel-like peel; 30 ml on the checked official page |
| Published formula signal | The brand labels it a 35% multi-acid peel and lists glycolic, lactic, gluconolactone, mandelic, salicylic and capryloyl salicylic acid among its AHA/BHA/PHA/LHA ingredients |
| Directions checked | Use once weekly in the evening, leave on for no more than 10 minutes, then rinse; patch test first |
| US price and stock snapshot | US$19 displayed on the checked official page, which also showed the item as backordered; both states can change |
| Label boundary | The official page targets experienced users; a 35% multi-acid label does not establish equal intensity or equal results versus The Ordinary |
COSRX's current list includes salicylic acid at 2% and a separate capryloyl salicylic acid entry alongside several acid families. That makes the product relevant to a broad multi-acid job search, but it is not the same acid list, vehicle, pH disclosure or use schedule as The Ordinary.
Does 35% mean COSRX is stronger?
No direct strength ranking. The Ordinary publishes “32% total” for five exfoliating acids and a pH range. COSRX publishes a “35% multi-acid” label and a different mix of AHA/BHA/PHA/LHA ingredients. Those brand-defined totals are not a shared test method, and the pages do not establish equal free-acid concentration, pH, delivery or result.
Routine match: yes, with a frequency difference. Both are high-strength rinse-off products with a 10-minute maximum. The Ordinary's checked directions say once or twice weekly; COSRX's say once weekly PM. Treat those directions as product-specific, and do not infer that one can be swapped into the other's schedule.
Side by side
| The Ordinary AHA 30% + BHA 2% | COSRX 35 Peel | |
|---|---|---|
| Broad job | High-strength rinse-off multi-acid exfoliation | High-strength rinse-off multi-acid exfoliation |
| Published formula signal | Five exfoliating acids; 32% total; pH 3.50–3.70 | 35% multi-acid label; AHA/BHA/PHA/LHA list including salicylic acid 2% and capryloyl salicylic acid |
| Texture cue | Peeling solution | Gel-like peel |
| Official frequency | Once or twice weekly PM | Once weekly PM |
| Maximum time | No more than 10 minutes | No more than 10 minutes |
| Size and checked price | 30 ml / US$9.50 | 30 ml / US$19; page showed backordered |
| Best switching question | Do you want The Ordinary's exact acid system and label frequency? | Do you want to investigate a Korean multi-acid peel with a different formula and once-weekly brief? |
| Verdict here | Same broad rinse-off acid job; different published formulas, label schedules and price context. Not a formula dupe. | |
Choose by the reason you are switching
- You want the same acid formula: COSRX does not qualify. Its acid families, supporting ingredients and current disclosure are different.
- You want a Korean-brand option: COSRX is a candidate for the same broad rinse-off multi-acid step, with a once-weekly official schedule and a different gel-like texture cue.
- You want a lower displayed price: the checked official US price for COSRX is higher than The Ordinary's. Do not use “cheaper” as this page's angle; market, shipping, currency and stock can change.
- You are comparing the headline percentages: 32% and 35% are not directly comparable brand totals. Read the ingredient list, pH disclosure and directions for the exact version.
- You are new to acid exfoliation or have a skin concern: follow the current label and ask a qualified clinician about health questions. This page is not a diagnosis, treatment plan or safety guarantee.
