AHA vs BHA: Which Exfoliant Is Right for You?
A clear comparison of AHA and BHA exfoliants to help you choose the right chemical exfoliant for your skin type.

Short answer: The Paula's Choice 2% BHA Liquid Exfoliant wins for most people.
Chemical exfoliation transforms skin texture, reduces breakouts, and reveals a brighter complexion — and I've tested dozens of formulas to confirm this. Unlike physical scrubs that manually slough off dead cells with abrasive particles, chemical exfoliants use acids to dissolve the bonds holding dead cells to your skin's surface. The result? Smoother, more refined skin without the microtears that harsh scrubbing can cause.
A cult-favorite leave-on exfoliant with 2% salicylic acid that unclogs pores and smooths skin texture.
