- doubles the efficacy of vitamins c and e
- protects skin against DNA damage, is anti-mutigenic
- a potent antioxidant, providing photoprotection and effectively protecting against UV radiation
According to EWG, ferulic acid is also anti-microbial, absorbs UV light and is also used as a preservative.
A study done with 12 women showed that a topical antioxidant complex containing vitamins C and E and ferulic acid had potential photoprotective effects against acute photodamage in human skin.
What would have been more interesting is first, if the study had more patients, a sample of 12 women is just not enough. Second, I would have preferred to see ferulic acid studied against different types of Vitamin C, Vitamin E and even popular antioxidants high in vitamin C like acai or pomegranate. That would certainly put things into perspective. Third, the word potential is very telling.
