1) Ferulic Acid's main function is its ability to act as a potent free-radical scavenger and antioxidant.
2) It reduces tyrosinase activity by directly binding to the enzyme tyrosinase. So it functions as an anti-pigment agent.
3) It boosts the effectiveness and stability of a complex containing Vitamin C and Vitamin E.
4) It accelerates wound healing by increasing precursors of collagen and is commonly found in plant tissues but also made synthetically.
Overall Ferulic Acid is one of the best-studied antioxidants we have to date, along with L-Ascorbic Acid and a few others.
