| 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 brightening flagship — licorice root extract as ingredient #1 (genuinely meaningful tyrosinase inhibitor concentration) + niacinamide + acetyl glucosamine + Korean white ginseng saponins + peony, ginkgo, scutellaria, rehmannia, ophiopogon, polygonatum traditional Korean herbal cocktail. Direct competitor to SK-II GenOptics Spot Essence at half the price with a fundamentally different brightening chemistry — herbal-led rather than ferment-led. |
