COSRX AHA/BHA Clarifying Treatment Toner is a powerful toner that helps to exfoliate and clarify the skin. It contains a blend of alpha hydroxy acids (AHAs) and beta hydroxy acids (BHAs) that work together to remove dead skin cells, unclog pores, and improve skin texture. This toner also helps to balance the skin's pH levels and control excess oil production. It is suitable for all skin types, including acne-prone and sensitive skin. With regular use, COSRX AHA/BHA Clarifying Treatment Toner can help to reduce the appearance of blemishes and promote a smoother, more radiant complexion.
