COSRX AHA/BHA Clarifying Treatment Toner is a gentle exfoliating toner that combines AHA and BHA with botanical ingredients to improve skin texture and control pores. This multi-functional toner helps eliminate impurities, exfoliate dead skin cells, and maintain hydration in one step. The toner contains natural AHA and BHA derived from White Willow Bark and Apple Water (10% each) to gently exfoliate while soothing ingredients like Allantoin and Panthenol help moisturize the skin. For best results, apply after cleansing using a cotton pad, avoiding the eye and mouth area. When using during daytime, follow with SPF 30 or higher sunscreen. Not recommended for use with other acids or during pregnancy/breastfeeding.
