Sungboon Editor Silk Peptide EGF Intensive Gold Mask is a Korean gold hydrogel mask with a silk peptide complex, EGF, niacinamide, hyaluronic acid and colloidal gold. It helps hydrate dry skin, smooth the look of fine lines and make skin look firmer, plumper and more radiant. The mask starts beige and turns transparent as the essence absorbs, so you can see it working. Wear it for 3–4 hours, or leave it on overnight as the last step of your night routine. Each box has 4 individually packed 37 g masks, ideal for intensive weekly care, special occasions or a pre-event glow.
