goop beauty, 20% vitamin c + hyaluronic acid glow serum

Brand new, never used. Expires 11/26. This daily glow face serum combines two skin-care powerhouses, L-ascorbic acid (proven in research to be the purest, best-for-skin form of the powerful antioxidant vitamin C) and moisturizing hyaluronic acid (a hydrator that’s naturally present in the body). The unique two-part design maximizes potency and freshness, delivering a serum that stays active all the way through its use while remaining paraben-free. Before your first use, mix the super potent 20% vitamin C powder with the hyaluronic acid serum. (There are three different molecular sizes of hyaluronic acid, to penetrate different layers of the skin, as well as the antioxidant superfruit Australian kakadu plum.) The ingredients work synergistically to help brighten the appearance of the skin, significantly improving its firmness, tone, texture, and hydration and leaving it looking radiant, luminous, and healthy.
