Ferulic acid is a plant-derived phenolic antioxidant naturally present in the cell walls of many plants (rice, oats, wheat, coffee seeds). It belongs to the hydroxycinnamic acid family.
In scientific literature, ferulic acid is associated with neutralizing a broad spectrum of free radicals, notably those generated by UV and pollution. Its molecular structure is linked in scientific literature to absorbing part of ultraviolet radiation, contributing to protection against photo-induced oxidative stress.
One major interest of ferulic acid documented in formulation is its association in literature with potentiating other antioxidants, particularly vitamins C and E. Reference studies report that a combination of ferulic acid + vitamin C + vitamin E is associated with a complementary antioxidant profile broader than vitamin C alone.
Ferulic acid is also documented for its contribution to the stability of cosmetic formulas containing vitamin C, limiting its oxidation. This dual antioxidant and stabilizing action in formula makes it a recognized active ingredient in serums and skincare associated with protection against oxidative stress.
In summary, a documented antioxidant active ingredient associated in scientific literature with skin protection against oxidative stress and supporting the efficacy of other actives in formula.
