BHA Blackhead Power Liquid Exfoliant

A 100 ml exfoliating liquid whose base is willow bark water, with betaine salicylate as the BHA and niacinamide alongside it; arginine, panthenol and sodium hyaluronate finish a ten-line formula. COSRX suggests two or three times a week to begin with, building up as skin allows, and it can sit in the toner or essence step. Sunscreen is required if it is used in the morning.
