COSRX AHA/BHA Clarifying Treatment Toner is a gentle exfoliating toner that combines AHA and BHA to improve skin texture and control pores. This dual-action formula helps remove dead skin cells, control oil production, and maintain skin clarity while providing hydration. The toner contains natural AHA and BHA derived from willow bark and apple water, along with soothing ingredients like allantoin and panthenol. 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, vitamin C, or retinols in the same routine. Should be avoided during pregnancy and breastfeeding.
