Bha Blackhead Power Liquid

COSRX's BHA Blackhead Power Liquid earns a buy thanks to three evidence-backed actives—niacinamide, panthenol, and sodium hyaluronate—that collectively address tone, barrier repair, and hydration in a single exfoliating step. For a facial exfoliant, having ingredients with solid clinical backing rather than decorative botanicals makes this one worth the shelf space.
