| Verdict | Isntree's answer to the Estée Lauder Advanced Night Repair playbook — 91% bifida ferment at a fraction of the prestige price, with an Olive Young best-seller badge to back it up. | 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. |
