What it is: An antioxidant-rich serum with powerful 15% L-ascorbic acid plus lactic acid to visibly improve signs of aging.

Who it's for: All skin types.

What it does: Vitamin C is an essential vitamin that helps visibly improve skin density and is associated with healthy collagen levels. Lactic acid serves as a powerful delivery vehicle for other ingredients, as it increases their penetration into the skin, and thus their efficacy.

How to use: Once daily, apply 4-6 drops as an all-over treatment on clean, dry skin. May cause a slight tingling sensation until skin is acclimated.
