COSRX BHA Blackhead Power Liquid is an exfoliating serum. The formula contains 4% Betaine Salicylate, a natural exfoliant derived from plants. It helps to dissolve impurities and debris from pores while clearing away dead skin cells. it also contains Hyaluronic Acid, Willow Bark Extract, and Niacinamide to hydrate and brighten the skin.
BHAs are oil soluble. They not only work on the skin’s surface, but also penetrate deeper and unclog pores and treat blemishes. This is why BHAs are preferred for those with normal to oily and clogged skin. BHAs have natural skin-calming properties, as well as anti-inflammatory and antibacterial activities and therefore can benefit those prone to redness and rosacea.
