| 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. | Sioris uses green tea water as the base instead of plain water — the entire formula is built on the antioxidant foundation of Camellia sinensis. Centella asiatica and panthenol calm reactive skin, beta-glucan strengthens the barrier, and the absence of fragrance and essential oils means nothing in this bottle will trigger the inflammation it's designed to reduce. Korean ampoule technology applied to the sensitive-skin problem with zero compromise. |
