The COSRX BHA Blackhead Power Liquid is a gentle chemical exfoliant formulated with Betaine Salicylate (BHA 4%) that penetrates deep into the pores to remove excess sebum, dead skin cells, and blackheads. It helps clear congested pores, refine skin texture, and prevent future breakouts without over-drying the skin. Enriched with Niacinamide and Willow Bark Water, this toner-like essence smooths rough skin and restores radiance for a clear, healthy-looking complexion.
