Ferulic Acid Ferulic Acid
Ferulic acid is an organic phenolic acid that occurs naturally in plant cell walls (mainly in grains, rice, oats and apples), where it serves as their natural shield against UV radiation. In cosmetics it is used primarily as a powerful next-generation antioxidant — significantly more effective than vitamin C or E alone. It shows an exceptional synergistic effect: combining ferulic acid with vitamins C and E strengthens their photo-protection up to 8-fold, which is why it is an indispensable ingredient in antioxidant daytime formulas. It effectively protects against photoaging, reduces hyperpigmentation, counteracts oxidative stress and prevents the formation of wrinkles. Ideal in SPF products, antioxidant daytime serums and for skin exposed to UV radiation and urban pollution.
Photo-Protection0.5% ferulic acid + 15% vitamin C + 1% vitamin E: 8x stronger photo-protection, 96% reduction in thymine dimerization under UV (Lin et al., 2005).
This aromatic phenolic acid stabilizes vitamin C in solution (prevents oxidation). It directly neutralizes hydroxyl and peroxide radicals. It inhibits lipid peroxidation.
