COSRX BHA Blackhead Power Liquid is a Korean leave-on exfoliant for oily, congested and blackhead-prone skin. Four percent betaine salicylate penetrates excess sebum inside pores and helps reduce blackheads, rough texture and visible congestion.

Willow bark water, niacinamide, panthenol and sodium hyaluronate support hydration and a clearer, more even-looking complexion. The lightweight liquid is potent, so introduce it gradually and avoid combining it with other strong actives in the same routine.

Use in the evening after cleansing and toner. Apply a thin layer once or twice per week, avoiding the eye area. Increase slowly as tolerated and use sunscreen every day.
