Ferulic Acid

Ferulic acid is a naturally occurring antioxidant found in the cell walls of plants like rice, oats, and apples. In skincare, it does two important jobs at once: it works as a standalone antioxidant, helping to defend the skin against oxidative stress from UV radiation and pollution, and it acts as a potency booster for Vitamin C and Vitamin E. When ferulic acid is formulated alongside these vitamins, it stabilizes both and has been shown to double their photoprotective effectiveness. Because Vitamin C is notoriously unstable and prone to degrading when exposed to light and air, ferulic acid is an essential part of any well-formulated Vitamin C serum.
