| 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. | Real Barrier's soothing ampoule is what you layer under the Extreme Cream on your worst barrier days — post-procedure, post-retinoid-burn, post-weather-damage. Madecassoside + asiaticoside + allantoin + panthenol + ceramide NP is the complete Korean calming stack in one bottle. Fragrance-free, no fillers, works fast. The derm-recommended ampoule for people who don't know what a derm-recommended ampoule is. |
