| 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. | Tia'm's targeted acne serum — salicylic acid (BHA) + tea tree leaf oil + Centella asiatica + niacinamide in a multi-pathway acne formulation. The combination of synthetic salicylic + natural tea tree gives this a genuine antimicrobial + exfoliating action without crossing into irritation territory. |
