| Verdict | Amorepacific's clinical retinol arm. IOPE's 0.1% retinol paired with peptide support is what Korean dermatologists recommend before jumping to tretinoin — effective enough for visible texture change at 8 weeks, gentle enough to not wreck your barrier on week one. | 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. |
