BHA Blackhead Power Liquid
$24.00
4% betaine salicylate dissolves blackheads and keeps pores clear. Gentler than traditional BHA, effective on the most stubborn congestion.
The Story
COSRX replaced harsh salicylic acid with betaine salicylate — a plant-derived BHA that penetrates pores without the skin stripping common to conventional exfoliants.
