The Paula's Choice SKIN PERFECTING 2% BHA Liquid Exfoliant is a gentle, leave-on salicylic acid treatment that unclogs pores, reduces blackheads, smooths fine lines, and improves overall skin texture without the harshness of physical scrubs. This fragrance-free, liquid exfoliant uses 2% BHA (salicylic acid) to penetrate deep into pores and remove dead skin cells, while green tea extract provides antioxidant protection and soothing benefits. Customers consistently praise its effectiveness for clearer, smoother skin within days, noting it's gentle enough for daily use on all skin types yet delivers noticeable results for everything from enlarged pores to aging concerns.
