Goop Beauty Goop glow 20% vitamin C + hyaluronic acid glow serum

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 staying paraben-free.
