| Verdict | 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. | The product that made Numbuzin a household name in Korea. At 82% galactomyces ferment filtrate, this is essentially a more affordable, modernized version of the fermented essence concept popularized by SK-II and Missha. The galactomyces base genuinely improves skin texture and brightness over time, and the addition of niacinamide amplifies the effect. The glow is visible from the first application, though the lasting transformation takes weeks. One of the best value treatment serums in current K-beauty. |
