| 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. | Sulwhasoo's plum blossom (Prunus mume) ferment franchise hero — niacinamide + adenosine + honey + 8 traditional Korean herbal extracts (white peony, korean lotus, polygonatum, rehmannia, licorice, korean pine, etc.). The brand's pivot from the heritage ginseng line (Concentrated Ginseng Cream + Eye Cream + Renewing Serum, all in catalog) into the plum-blossom franchise. Sephora-distributed Korean prestige at $130 — sister product to the Bloomstay Cream and Eye Cream. |
