Cosrx BHA Blackhead Power Liquid is a targeted exfoliating treatment formulated with 4% salicylic acid to penetrate pores and dissolve sebum buildup. This lightweight liquid effectively addresses blackheads and congestion while minimizing irritation through a pH-balanced formula. Ideal for oily and combination skin types, it works best as part of an evening routine. Apply to clean skin before moisturizer, allowing the BHA to work overnight for visible clarity and refined texture within weeks of consistent use.
