COSRX AHA/BHA Clarifying Treatment Toner combines alpha and beta hydroxy acids to gently exfoliate and renew your skin. BHA penetrates pores to clear dead skin cells and prevent congestion, while AHA exfoliates the surface, revealing a brighter and smoother complexion. Regular use promotes even skin tone, reduces blackheads and blemishes, and maintains optimal pH balance, resulting in a soft, glowing appearance. This 150ml toner is ideal for enhancing skin clarity and texture with expert care.
