| 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. | O HUI's flagship anti-aging ampoule and the brand's most-imported product internationally. Built on the brand's stem-cell-and-peptide complex with adenosine + niacinamide for the firming-and-brightening base. The 50ml size is generous for the prestige tier; the formulation is dense without being tacky. The entry point to the O HUI brand experience. |
