COSRX BHA Blackhead Power Liquid is a gentle yet effective exfoliating treatment designed to unclog pores, reduce blackheads, and refine skin texture. Formulated with natural BHA (betaine salicylate), it penetrates deep into pores to dissolve excess sebum and dead skin cells without causing irritation. Ideal for oily, combination, and acne-prone skin, this lightweight essence helps improve overall clarity and smoothness over time. With continued use, it visibly minimizes pores, controls excess oil, and promotes a clearer, healthier-looking complexion while maintaining the skin’s natural balance.
