| Verdict | Iope's mix-at-home vitamin C — a two-part system (ascorbic acid powder + emulsion base) that you blend at the moment of application for a fresh 23% L-Ascorbic Acid serum. The format solves the LAA oxidation problem definitively: the vitamin C stays in dry-powder form until activation, giving you fresh clinical-grade vitamin C every time. The 23% concentration is at the higher end of LAA tolerability — meaningful brightening without crossing into irritation territory for most skin. | iUNIK signature product and one of the best-kept secrets in sensitive-skin K-beauty. 70% beta-glucan — a powerhouse humectant and soothing agent — combined with a minimalist supporting cast. The result is a serum that hydrates like hyaluronic acid but also calms reactive skin the way centella does. Cult favorite for a reason. |
