Ferulic Acid is a white to pale-yellow, needle-like crystalline antioxidant known for its strong free-radical neutralizing and brightening effects. It enhances microcirculation, supports an even skin tone, and provides mild preservative-boosting benefits for greater formulation stability.

A key advantage of Ferulic Acid is its synergy with Vitamin C (ascorbic acid) and Vitamin E (tocopherol). When used together, Ferulic Acid helps stabilize these antioxidants, significantly improving their resistance to oxidation while boosting their photoprotective and brightening performance. This makes it a preferred component in advanced anti-aging and brightening serums.

Soluble in alcohol and oils, it can be incorporated into serums, essences, and emulsions. Typical usage levels range from 0.1–10%, depending on the formulation system and desired potency.
