| 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. | Mary & May's daily multivitamin glow serum — niacinamide + ascorbyl glucoside + tocopheryl acetate in a minimalist clean-formula approach. The accessible-tier alternative to higher-priced multivitamin serums (I Dew Care Bright Side Up, Glow Recipe Watermelon Pink Juice) at $18. |
