Ferulic acid derivatives are widely used in skin care, primarily for their antioxidant properties. Scientific studies support their role in protecting the skin against oxidative stress induced by UV radiation and pollution. As a potent phenolic antioxidant, ferulic acid helps to neutralize free radicals, thereby reducing visible signs of aging such as fine lines, wrinkles, and hyperpigmentation.^1,2 It is also commonly formulated with vitamins C and E, as research demonstrates that ferulic acid stabilizes these vitamins and enhances their photoprotective effects.³ For example, a landmark study published in the Journal of Investigative Dermatology in 2005 showed that a topical solution containing 15% vitamin C, 1% vitamin E, and 0.5% ferulic acid doubled the photoprotective capacity of the skin compared to vitamin C and E alone.³ Additionally, ferulic acid exhibits anti-inflammatory and skin-brightening properties, further benefiting overall skin health.⁴ While most evidence comes from in vitro and some human studies, the collective data provide a strong scientific rationale for the inclusion of ferulic acid derivatives in skin care formulations aimed at improving skin texture, tone, and resilience to environmental damage.
