The Ordinary Ascorbyl Glucoside Solution 12, Vitamin C Serum - 1 fl oz - Ulta Beauty: Oil-Free, Vegan, Alcohol-Free, For Nor

Vitamin C is an effective antioxidant, brightens the skin tone and reduces signs of aging. In its direct form, Vitamin C is unstable in water. Ascorbyl Glucoside is a water-soluble derivative of Vitamin C. It is much more stable in water, but less potent than direct L-Ascorbic Acid. Being more compatible with water allows for a very pleasant serum texture. It is considered a gold standard of Vitamin C derivatives due to its high stability and comfortable use, but it's impossible to achieve extremely high L-Ascorbic Acid potency with this solution. Aside from the general benefits of direct Vitamin C, Ascorbyl Glucoside has been shown to offer specific skin brightening benefits.
