Ferulic acid is a powerful antioxidant found naturally in the cell walls of plants like oats, rice bran, and apples. While it works well on its own for neutralizing harmful free radicals (unstable molecules emitted from air pollutants and cigarette smoke, for example) and reducing signs of aging, it’s often found in combination with other antioxidants, such as vitamin C and niacinamide, to maximize their effects. “Ferulic acid helps stabilize vitamin C, making it more effective and longer lasting,” explains Anand. “In fact, when combined with vitamin E and ferulic acid, vitamin C’s benefits — brightening skin, reducing hyperpigmentation, aiding collagen production — are significantly boosted.”
