Ester C is becoming more popular in skin-care lines as customers learn of the disadvantages of L-ascorbic acid. However since Ester C does still degrade over time, it is important to keep these products sealed and away from sunlight. Ester C is a water-soluble derivative of vitamin C. It's nonirritating, and more stable than L-ascorbic acid. Research is also finding that it appears to be just as effective as ascorbic acid in the stimulation of collagen production. Overall, Ester C is a better choice than vitamin C for people with sensitive skin. (Most vitamin C formulas are highly acidic and therefore produce exfoliation.) It is widely used in various cosmetics for its advantageous properties such as inhibitory effects on melanogenesis, promotion of collagen synthesis, and prevention of lipid peroxidation.
