What Is Ferulic Acid? Ferulic Acid Benefits & How To Use It

Like most other antioxidant ingredients, ferulic acid can provide a host of skincare benefits—chief among them being its ability to neutralize free-radical damage from pollution, ultraviolet light, and infrared radiation. 

“Ferulic acid’s main benefit is that it protects against UV-induced free radical damage that contributes to aging by inhibiting enzymes that increase free radical damage,” explains Dr. Gross. As a result, ferulic acid has been proven to help prevent the formation of hyperpigmentation, fine lines, and wrinkles while simultaneously protecting the integrity of the skin’s fibroblasts, collagen, and elastin so it can maintain its plump, youthful appearance. 

Ferulic acid also has anti-inflammatory properties, which studies have shown, can provide several therapeutic benefits, including helping to reduce the look of redness and post-inflammatory pigmentation (i.e., those red marks your pimples leave behind). 

Fu explains you’ll typically find ferulic acid paired with vitamin C and ascorbic acid, as it can not only help stabilize the ingredient but also enhance its antioxidative effects. In fact, a study suggests that ferulic acid has the potential to offer nearly twice the amount of photoprotection when combined with both vitamins C and E, hence why dermatologists and beauty experts alike are forever singing the praises of Skinceuticals’ legendary C E Ferulic serum

“I love to formulate ferulic acid with other ingredients like antioxidants because it works to give you even better protection from free radicals like UV rays, pollution, and blue light,” echoes Dr. Gross. “This is also why you see it combined with other actives like retinol and bakuchiol.”
