the ordinary · mid-range
Shares salicylic acid but it's a minor player behind 30% glycolic acid, making this a much stronger, different-feeling AHA-dominant peel rather than a BHA exfoliant dupe.
No price
The Inkey List · drugstore
It contains salicylic acid but as a leave-on treatment led by succinic acid, not a 2% BHA liquid exfoliant, so concentration and formula intent differ.
No price
Dermalogica · drugstore
Shares salicylic acid but this is a physical/enzyme rice-bran scrub with papain, a totally different exfoliation mechanism than a liquid BHA solution.
No price

L'Oréal · drugstore
Contains salicylic acid but is a sulfate/surfactant-based cleansing scrub with menthol and fragrance, very different from a leave-on BHA liquid exfoliant.
No price

We rank results with INCI-level analysis first, then fall back to the strongest active matches and closest alternatives so every product page still shows comparable options. Fallbacks stay within the same category as the source product, so cleansing balms only surface cleanser dupes instead of adjacent product types. Active Match % measures shared science-backed actives. Formula Similarity % measures total ingredient overlap when full INCI lists are available.
