| 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. | A budget vitamin C serum that punches above its weight. The ascorbic acid concentration is effective for gradual brightening, and the addition of niacinamide boosts the dark spot-fading effect. Not as potent as premium vitamin C serums, but at this price it is an excellent entry point. |
