1Shared hero active
Paula's Choice
ExfoliantPremiumEvening only
AcneRough TextureOilinessSensitive skinDamaged barrier

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.

The Ordinary
ExfoliantBudgetEvening only
CongestionOilinessAcne

A straightforward 2% BHA in a lightweight watery base with a little witch hazel. Effective pore and blackhead exfoliation at a rock-bottom price; the simple base means less of the soothing buffer found in pricier BHAs.
