| 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. | Sum:37°'s top-tier anti-aging elixir — the brand's answer to La Mer Genaissance and Sulwhasoo Concentrated Ginseng Serum. Built on the same Lactobacillus/Soybean fermented Cytosis complex as Secret Programming, but at higher concentration and with hydrolyzed collagen + adenosine for the deep-firming claim. Rich treatment that should be paired with patience: results build over 12+ weeks of consistent twice-daily use. |
