20% Vitamin C + Hyaluronic Acid Glow Serum

What it is: A daily serum that combines two skin-care powerhouses to help brighten the appearance of the skin, leaving it looking radiant, luminous and healthy.

Who it's for: Ideal for all skin types.

What it does: The unique two-part design maximizes potency and freshness, delivering a serum that stays active all the way through its use. 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.
