Ferulic acid is a plant-derived phenolic antioxidant that neutralizes free radicals and helps protect skin from UV-induced oxidative damage. It is frequently combined with vitamins C and E to enhance their stability and photoprotective effect.

Redness or erythema | Uncommon | Usually mild and resolves after discontinuation |
Allergic contact dermatitis | Rare | Sensitization possible but infrequently reported |
Discoloration of product (yellowing/oxidation) | Common | A stability issue rather than a skin reaction; does not indicate harm |
