It's one of COSRX's best sellers: a chemical exfoliant to treat whiteheads. We all have them, more or less: they're small, raised, white spots that tend to be located around the nose and forehead, although they can appear all over the face. Cosrx has designed this chemical exfoliant based on AHA acids, which help eliminate whiteheads and prevent them from appearing. The star ingredient is apple juice extract, a powerful acid that eliminates dead cells and evens out your skin's texture. In addition to this wonder, you'll also find glycolic acid (7%) in its formula, which smoothes skin texture, leaving it softer and more even.
