COSRX BHA Blackhead Power Liquid is a lightweight, leave-on exfoliant specially formulated for oily, combination, and blemish-prone skin. Featuring 4% betaine salicylate, a plant-derived form of BHA, it gently yet effectively penetrates deep into the pores to help dissolve excess sebum, break down dead skin cells, and reduce the appearance of blackheads and congestion.

Unlike surface-level exfoliants, BHAs work both on the skin’s surface and within the pores, making them ideal for targeting clogged pores, texture irregularities, and persistent impurities. To balance its exfoliating action, the formula is enriched with hyaluronic acid to maintain hydration and prevent dryness, while niacinamide supports a stronger skin barrier and promotes a clearer, more even complexion.

With consistent use, the skin becomes smoother, less congested, and visibly refined, making this liquid a favorite among those seeking an effective yet gentle approach to pore care.
