Cosrx BHA Blackhead Power Liquid 100ml

Cosrx BHA Blackhead Power Liquid is the ultimate pore-clearing treatment with 4% betaine salicylate (a gentler form of BHA) in a willow bark water base. BHA is oil-soluble, meaning it penetrates deep into pores to dissolve sebum, dead skin cells, and blackhead-causing buildup that water-soluble acids can't reach.

88% willow bark water provides a natural source of salicylates. Niacinamide brightens and refines pore appearance. Panthenol strengthens the barrier. Sodium hyaluronate maintains hydration. Arginine conditions. The minimal, clean formula contains just 10 effective ingredients — no unnecessary fillers. Free from parabens, sulphates, artificial colours, fragrances, alcohol, mineral oil, essential oils, and silicone.

Pro tip: This is the BHA counterpart to the AHA 7 Whitehead Power Liquid — use the BHA for deep pore concerns (blackheads, sebaceous filaments, oiliness) and the AHA for surface concerns (whiteheads, dullness, texture). The betaine salicylate formulation is gentler than pure salicylic acid, making it tolerable for more skin types. Apply after the AHA/BHA Clarifying Treatment Toner for enhanced absorption. For stubborn blackheads on the nose, try the "50 grits" method: apply this liquid, wait 15 minutes, then gently massage with an oil cleanser to dissolve the loosened sebum plugs.
