| 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. | The ampoule that started the salmon-DNA craze — and still the gold standard in the PDRN space. Rejuran's patented c-PDRN® at 0.5% concentration is the topical version of the injectable Rejuran Healer that Korean aesthetic clinics have used since 2014 for skin regeneration. The DOT® delivery technology enhances penetration of the polynucleotide fragments into the dermis, where they stimulate fibroblast activity, boost collagen synthesis, and improve cellular turnover. The result is measurably firmer, smoother, more luminous skin over 4-8 weeks — the kind of gradual-but-real improvement that doesn't come from hype ingredients. At $52 it's premium for K-beauty but a fraction of the $300+ injectable treatment it's derived from. Available at Sephora US. |
