Glass Skin Refining Serum Superskin Ingredients: Peach Extract: a powerhouse chock full of vitamins, minerals, and essential fatty acids known to help keep skin visibly firm, radiant and resilient. Niacinamide: a form of Vitamin B3 with anti-inflammatory and anti-oxidative benefits; creates a visibly brighter appearance and targets dark spots. East Asian mountain yam extract: helps to create more supple skin and reduce flakiness for the ultimate glassy skin. Madecassoide: derived from Centella Asiatica extract, noticeably soothes skin and helps rejuvenate. Hyaluronic acid complex: a proprietary blend of short-chain, medium-chain and long-chain hyaluronic acid molecules helps provide hydration at every level of skin; short-chain molecules sink into the deeper layers, while medium-chain molecules fill in the layers closer to the surface of the skin, and long-chain molecules lock in moisture on the skin's surface so that skin is plumped up from within while the outer layer becomes radiant. Peptide complex: a proprietary blend of peptides helps boost collagen production, visibly improving fine lines and deeply-etched wrinkles for a smoother, glassier appearance. Only used once.
