Paula's Choice SKIN PERFECTING 2% BHA Liquid Exfoliant is a fast-absorbing liquid exfoliant that removes built-up dead skin cells and fights blackheads and breakouts. It contains 2% BHA (Salicylic Acid), known for its anti-inflammatory properties, which helps to reduce blackheads, blemishes, and redness. The lightweight, water-based formula absorbs quickly without leaving an oily or greasy residue, making it ideal for use on the go. This leave-on formula penetrates deep into pores to eliminate dirt buildup and cleanse dead skin cells, leaving your skin cleansed, refreshed, and blemish-free. It is 100% fragrance-free and suitable for normal, combination, and oily skin types. Directions: Apply once or twice daily after cleansing and toning. Lightly soak a cotton pad and apply over the entire face, including the eye area (avoid the lower lash line and eyelids). Do not rinse. For daytime, follow with a broad-spectrum sunscreen rated SPF 30 or greater. For nighttime, follow with the rest of your routine. Start slowly by applying every other day and note skin’s response, then gradually increase to twice daily if tolerated. This product has an optimal pH range of 3.2-3.8 for maximum effectiveness without irritation. Paula's Choice never tests on animals.
