Paula's Choice SKIN PERFECTING 2% BHA Liquid Exfoliant — 30% Off

Paula’s Choice 2% BHA Liquid Exfoliant is the salicylic-acid serum that built the brand and remains the gold standard for chemical exfoliation in dermatology forums and skincare circles alike. Salicylic acid is oil-soluble, which lets it penetrate clogged pores rather than working only at the surface like glycolic or lactic acid — that’s why it’s the active of choice for blackheads, whiteheads, and the early acne that surface-only exfoliants can’t reach. The lightweight liquid format is fragrance-free and leaves no residue, making it easy to layer with retinol routines or under sunscreen without the pilling that thicker AHA serums cause. Paula Begoun has built her brand around evidence-based formulations and clear ingredient transparency, and this product anchors that reputation with over 114,000 reviews averaging 4.5 stars. At $25.90 — 30% off the $37.00 list — this is the largest list-price discount the line has hit in months and a strong window to stock the bottle most users settle on for daily or every-other-night use.
