100% Pure Multi Vitamin PM Serum is a potent serum that works to reduce signs of ageing whilst promoting a healthy, radiant complexion. Formulated with Niacinamide and Vitamin C, two anti-ageing superstars that are not usually found together because of difference in pH levels. However, this serum has been formulated with Magnesium Ascorbyl Phosphate, the most stable form of Vitamin C, that makes them work harmoniously together to restore a youthful, healthy, glowing complexion. Balanced serum can also be used around eyes, including your lids.
