What It Is: A dermatologist-developed liquid exfoliating lotion that clears the way for smoother, brighter skin. What It'S For: Very dry skin types (type 1). What It Does: Sweeps away pollution, grime, dulling flakes to reveal smoother, clearer skin. Preps skin for moisturizer-exfoliated skin is more receptive to hydration and treatment products. For drier skins, twice-daily exfoliation helps remove surface flakes that can be a barrier to moisture absorption. Even helps fine dry lines disappear.
