<p data-start="145" data-end="1512">COSRX BHA Blackhead Power Liquid is a highly effective chemical exfoliating treatment formulated to deeply cleanse pores, dissolve stubborn blackheads, and improve overall skin clarity while maintaining hydration and comfort. Powered by 4% natural BHA derived from willow bark water, this liquid exfoliant penetrates beneath the skin surface to loosen and remove pore-clogging debris, excess sebum, and accumulated dead skin cells that often lead to blackheads, whiteheads, and congestion. Unlike harsh physical scrubs, the lightweight liquid formula works gently yet efficiently, helping refine skin texture and reduce the appearance of enlarged pores over time. Willow bark extract supports calming and balancing care, while niacinamide helps brighten the complexion, improve uneven tone, and support a healthier skin barrier. Sodium hyaluronate provides hydration to prevent dryness commonly associated with exfoliation, ensuring the skin feels refreshed rather than stripped. Designed for use in the evening routine, this concentrated formula is ideal for gradually improving congested areas such as the T-zone and chin, promoting clearer-looking skin with consistent use. When introduced slowly and used as directed, the skin appears smoother, more refined, and visibly clearer, revealing a healthier, more vibrant complexion that feels balanced and rejuvenated.</p> <h3 data-start="1519" data-end="1537">Key Features</h3> <p data-start="1538" data-end="1995">This BHA exfoliating liquid penetrates deeply to cleanse clogged pores and dissolve blackheads while gently removing dead skin cells.
