Antioxidant (plant phenolic)
Ferulic Acid
INCI: Ferulic Acid·Studied at 0.5–1%·Moderate evidence
A plant-derived antioxidant best known as the stabiliser in "CE ferulic" serums. It props up vitamins C and E and adds its own antioxidant support, usually dosed below 1% by design.
Studied for
- ·Antioxidant support alongside vitamins C and E
- ·The appearance of protected, even-looking skin
How it’s thought to work
Studied for association with stabilising and boosting a vitamin C + E antioxidant network; on its own the appearance evidence is more limited than as part of that trio.
Questions
- Is ferulic acid fairy-dusted when it sits below the 1% line?
- Not in a CE-ferulic formula. Ferulic is meant to sit around 0.5% there. Its job is to stabilise the vitamin C and E, not to headline, so a low position on the label is by design rather than a sign of under-dosing.
