Vitamin C is an effective antioxidant, brightens the skin tone and reduces signs of aging. In its pure form, Vitamin C is unstable in water. Ascorbyl Glucoside is a water-soluble derivative of Vitamin C. Brightening Serum is much more stable in water but it is 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 pure Vitamin C, Ascorbyl Glucoside has been shown to offer specific skin brightening benefits. The Ordinary's portfolio of Vitamin C includes the following formulations.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. We have developed a guide that offers guidance on the formulations of Vitamin C offered under The Ordinary range. It also offers education on Vitamin C itself and on the differences between formulations of Vitamin C at large.
