The Korean toner helps to refine skin texture in the first step of skincare, ensuring a smooth base for makeup application. This AHA BHA toner is particularly effective due to its inclusion of AHA/BHA/PHA ingredients, which gently exfoliate dead skin cells and impurities, leaving the skin clear and smooth. Additionally, the high concentration of tea tree extract in this pore care toner soothes and treats troubled skin, making it an essential part of any Korean skincare routine
