Ferulic acid is a plant-derived antioxidant commonly included in skincare products targeting hyperpigmentation and age spots (solar lentigines). Its scientific basis rests on its potent ability to neutralize free radicals and inhibit oxidative stress, both of which are implicated in the formation and darkening of age spots due to cumulative sun exposure and aging. In vitro studies have demonstrated that ferulic acid can suppress melanogenesis by inhibiting the activity of tyrosinase, a key enzyme involved in melanin production. Additionally, ferulic acid boosts the photoprotective effects of other antioxidants like vitamins C and E, helping to prevent further pigment accumulation when used in topical serums. Clinical evidence supporting ferulic acid for age spots is modest but growing. Some small-scale human studies and case series report improvements in hyperpigmentation and skin tone when ferulic acid is a component of combination antioxidant formulations. However, there is a lack of large, high-quality randomized controlled trials specifically examining ferulic acid as a solo treatment for age spots. The bulk of available data comes from its use in multi-ingredient products, making it difficult to isolate its individual effect. In summary, while there is a plausible scientific mechanism and preliminary evidence for ferulic acid in addressing age spots, the overall clinical evidence remains limited, warranting a moderate evidence rating.
