Ferulic Acid
What is Ferulic Acid?
Ferulic acid is a naturally occurring phenolic compound, chemically known as 4-hydroxy-3-methoxycinnamic acid, abundant in plant cell walls like those of rice bran, oats, wheat, and coffee beans. In cosmetics, it serves mainly as an antioxidant agent, scavenging free radicals to prevent lipid peroxidation in formulations and on skin. It enhances the stability and efficacy of other antioxidants such as vitamins C and E by regenerating them after they neutralize reactive oxygen species. Additionally, it acts as a mild preservative and antimicrobial, inhibiting microbial growth, and contributes to UV protection by absorbing certain wavelengths and reducing photo-induced damage. Typically incorporated into serums, creams, and sunscreens at low concentrations for stability and protective benefits.
