Is it just us, or does this Paula's Choice product look familiar? There's a reason for this: it hails from the same line as the skincare brand's beloved Skin Perfecting 2% bha Liquid Exfoliant - only, this iteration is in a lightweight gel form. Apply it every other day, before building up to twice daily, and let the salicylic acid-infused formula gently remove dead cells on the skin's surface as well as deep within the pores for a breakout-free result.
