Paula's Choice Skin Perfecting 2% BHA Liquid Exfoliant is a leave on liquid exfoliant designed to unclog pores, smooth rough texture, reduce blackheads, and reveal a clearer more radiant complexion. It is made for normal, combination, and oily skin types with concerns such as congested pores, blackheads, breakouts, uneven texture, dullness, rough patches, and oily T zones. The formula is powered by 2% salicylic acid BHA, which exfoliates both the skin surface and inside the pores to dissolve dead skin cell buildup, support clearer pores, and refine skin texture over time. Its lightweight fast absorbing liquid texture leaves no sticky residue and does not require rinsing, making it easy to include after cleansing. With consistent use, it helps reduce the appearance of enlarged pores, smooth visible roughness, calm congestion, and promote a more balanced, brighter, and healthier looking complexion. During daytime use, sunscreen is essential to protect freshly exfoliated skin.
