COSRX AHA/BHA Clarifying Treatment Toner is a gentle exfoliating toner that combines natural AHA and BHA with purifying botanical ingredients to improve skin texture and control pores. This dual-action toner helps eliminate impurities, exfoliate dead skin cells, and maintain hydration in one simple step. The toner contains white willow bark and apple water that help soothe irritation while providing gentle exfoliation. It also includes allantoin and panthenol for additional moisturizing benefits. For best results, apply after cleansing using a cotton pad, avoiding the eye and mouth area. When used during daytime, follow with SPF 30 or higher sunscreen. Not recommended for use with other acid products, retinols, or vitamin C. Should be avoided during pregnancy or breastfeeding.
