Quick answer: the closest dupe for the Paula's Choice 2% BHA Liquid Exfoliant is the The Ordinary Salicylic Acid 2% Solution — 70% active overlap, sharing Salicylic Acid. A much lower price for a comparable active core; you trade the acid blend and buffering, not the headline ingredients. Note the original also carries Green Tea Extract.
The contextWhy look for a 2% BHA Liquid Exfoliant dupe?
The reference-standard 2% salicylic acid exfoliant — formulated at the pH range where BHA actually works (3.2–4.0), with green tea for antioxidant support. Unclogs pores, softens blackheads and smooths texture. The reason so many other BHA products are compared to this one.
A good dupe isn't about a matching label — it's about matching the hero actives, the ingredients carrying the real work. For this exfoliant that means Salicylic Acid, Green Tea Extract. The alternatives below share that profile; where they differ is in texture, supporting ingredients and finish.

Are 2% BHA Liquid Exfoliant dupes really as good as the original?
A dupe matches the hero actives — the ingredients doing the measurable work — but rarely the full sensory experience. Texture, fragrance, supporting ingredients and exact concentrations differ, so treat a dupe as a value-led alternative rather than an identical copy.
How does Skin Stacker choose 2% BHA Liquid Exfoliant dupes?
We match products in the same category (exfoliant) that share hero actives (Salicylic Acid, Green Tea Extract), then rank by overlap and price. Matches are based on published INCI lists, not lab assays.
Compare them yourself
Skin Stacker is independent and receives no payment from any brand. "Dupe" matches are based on publicly disclosed INCI lists and shared hero actives — not on side-by-side lab testing. A shared active profile does not guarantee an identical experience: texture, fragrance, supporting ingredients and concentrations all differ. Formulations change — always re-check the current label before buying.
