SKIN1004 Hyalu-Cica Blue Serum is a targeted treatment serum designed to deliver immediate and lasting hydration while visibly calming stressed skin. The formula blends multiple sizes of hyaluronic acid to deliver moisture at different skin levels, together with cica-derived TECA actives to soothe irritation and support barrier recovery. The result is plumper, smoother skin with reduced sensitivity. The serum’s lightweight, non-sticky finish absorbs quickly and pairs easily with other actives and moisturizers. Ideal for dehydrated, sensitive, and combination skin types, it can be used daily as part of both morning and evening routines to maintain supple, resilient skin.
