The CosRx AHA/BHA toner gently improves skin texture. It contains alpha and beta hydroxy acids that work to exfoliate dead skin cells, clear congestion, and minimize the appearance of pores. Willow bark water and apple fruit water combine to brighten and even out skin tone, unveiling a smoother, more radiant complexion with continued use. This treatment toner preps the skin, allowing for better absorption of subsequent skincare products.
