| Verdict | A potent brightening serum that pairs 10% niacinamide with 4% tranexamic acid — two well-researched brightening ingredients with complementary mechanisms. This combination targets hyperpigmentation from multiple angles, and the results are visible within a few weeks of consistent use. The texture is clean and non-greasy, sitting well under moisturizer. At $20, this competes directly with serums costing twice as much. The only caveat: 10% niacinamide can cause flushing in some people, so patch test first. | 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. |
