Full description

Blackheads that won't budge, pores that stay visible, a complexion that looks dull however much you cleanse — COSRX BHA Blackhead Power Liquid is formulated for exactly that. A liquid exfoliant with 4% Betaine Salicylate that works deep inside the pore, dissolving excess sebum and built-up dead cells to reveal clearer, brighter skin.

A water-light texture, fragrance-free and alcohol-free. Apply it like a toner after cleansing. No stinging, no tightness.

What users really say

— The blackheads on my nose have reduced by 80% in 2 months
— My pores have shrunk and there are no more blackheads. One bottle lasts a long time, the price is justified
— My skin didn't get worse even though it's sensitive — it's a BHA on the gentle, well-tolerated side

Key actives

— Betaine Salicylate 4% — a gentler form of BHA than classic salicylic acid, it penetrates the pore to deep-clean it
— Willow bark water (Salix Alba) — 65% of the formula, naturally soothing and purifying
— Niacinamide — reduces post-breakout marks and evens out skin tone
— Panthenol + Sodium Hyaluronate — hydrate while the BHA exfoliates

Good to know

Start once a week to let your skin adjust, then increase gradually. Don't use at the same time as another exfoliant. Always follow with SPF50+ in the morning.
