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.

Topical Vitamin C offers a wide array of benefits to the skin. However, many forms of Vitamin C and many more formulations of Vitamin C are available commercially with a potential to confuse the audience.
