Paula's Choice Skin Perfecting 2% BHA Liquid Exfoliant is a global bestseller and a fast-absorbing liquid exfoliant that removes built-up dead skin cells, fights blackheads, and controls oil for clear, glowing skin. Fortified with 2% salicylic acid (BHA), this gentle exfoliant mimics the natural exfoliation process by shedding extra layers and unclogging pores, making it effective for reducing breakouts and blackheads while also offering soothing properties. Unlike harsh scrubs, this leave-on exfoliant has an optimal pH range for maximum effectiveness without irritation. It is ideal for normal, combination to oily skin types, penetrating quickly into pores, blackheads, and pimples. To use, lightly soak a cotton pad and gently apply over the entire face and neck, including the eye area (avoiding the lash line and eyelids), and do not rinse. Start by applying every other day and noting skin’s response, then use up to twice daily. For daytime, follow with a broad-spectrum sunscreen rated SPF 30 or greater. For nighttime, follow with the rest of your routine.
