Times vary by format: clay or quick masks often work in about 3–5 minutes; cream or rinse-off K‑beauty masks are usually around 10 minutes; pre‑soaked sheet masks typically recommend about 20 minutes; and some gel treatments are intended as overnight boosts.
Typical hydrators are multiple forms of hyaluronic acid and squalane; some formulas also list agave and prickly pear/cactus extracts for additional moisture support.
Exfoliation appears as chemical acids like lactic and glycolic acid; enzymatic or powder exfoliants such as mung‑bean enzyme and ultra‑fine mung‑bean powder; and physical/adsorbing agents like kaolin clay, charcoal, and, in some formulas, bamboo buffing particles.
