COSRX AHA/BHA Exfoliating Treatment Toner is a daily maintenance solution designed to balance skin pH and condition the surface. With low concentrations of Glycolic Acid and Betaine Salicylate, it functions as a preparatory step rather than a corrective peel. This approach ensures the skin's moisture barrier is maintained while providing very mild chemical exfoliation.
The formula utilizes Mineral Water, including Willow Bark and Apple Fruit Water, as a base to provide natural sources of salicylates and malic acid. This alcohol-free and fragrance-free formulation is highly tolerated and serves as an excellent "prep" for subsequent professional-grade serums. It is specifically designed to avoid the sensitivity often associated with higher-percentage acid products.
