One of Korea's long-standing, playful beauty names, Etude (formerly Etude House) has been part of the Amorepacific family since 1985 — best known for its makeup and its gentle SoonJung skincare, all pink packaging and easy charm. At EE-MO it's represented by the AC Clean Up Cleansing Foam, a BHA-and-tea-tree cleanse that leaves oilier, blemish-prone skin feeling fresh and clean.
