The SKIN PERFECTING 8% AHA Gel Exfoliant & 2% BHA Liquid Duo work in tandem to exfoliate skin both above and below the skin's surface, delivering radiant, brighter, more refined results. The SKIN PERFECTING 8% AHA Gel is a completely non-abrasive, leave-on exfoliant that gently and naturally helps shed built-up layers of dead skin. This unique formula revitalizes skin's surface, creates noticeable radiance, smooths the appearance of winkles, and makes your skin look and feel remarkably soft due to its skin hydration properties. With the exfoliating benefits of glycolic acid, skin-soothing plant extracts and antioxidants, and an optimal pH range of 3.5-3.9, the 8% AHA also contributes to brightening and evening skin tone, and improves the feeling of firmness. The SKIN PERFECTING 2% BHA is our #1-selling exfoliant around the world--for good reason! Non-abrasive and suitable for daily use on all skin types, it effectively unclogs pores, optimizing skin renewal and clarity for remarkably smoother, perfect-looking skin, smaller pores, a refined texture, and less visible lines and wrinkles. All Paula's Choice products are 100% fragrance free, clinically proven to be non-irritating, and never tested on animals.
