goop Beauty 20% VITAMIN C + HYALURONIC ACID GLOW SERUM

Never been opened. Suitable for all skin types. Apply to clean, dry face and neck in the morning and evening. This daily glow serum combines two skin-care powerhouses, L-ascorbic acid (proven in research to be the purest, best-for-skin form of the 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.
