Last updated: June 2026 · Reviewed by the FactoWiki Editorial Team for clarity and source accuracy
Quick summary
Ferulic acid is a plant antioxidant used mainly in skincare, where it stabilises and boosts vitamins C and E. Topical use is well established; oral claims are limited.
What is Ferulic Acid?
Ferulic acid is an antioxidant found in the cell walls of grains, seeds and some fruits and vegetables, used widely in antioxidant skincare and sold as a supplement.
What Ferulic Acid is commonly used for
In supplements, Ferulic Acid is most often included for skin & anti-aging support. It is used as nutritional support, not as a treatment for any medical condition — the distinction matters, because the claims on a sales page are often stronger than the evidence allows.
How Ferulic Acid works
Ferulic acid neutralises free radicals and, importantly in skincare, stabilises and enhances the antioxidant effects of vitamins C and E, improving their protection against UV damage.
What the evidence says
Here's an honest snapshot of what published research suggests about Ferulic Acid — including where the evidence is limited.
- Topically, ferulic acid is well established for boosting vitamin C/E serums and protecting skin from oxidative and UV stress. Oral supplement evidence for distinct benefits is limited.
- Study quality and doses vary, and a result seen in research doesn't guarantee the same for any individual — use the sources below to check the current evidence on Ferulic Acid rather than relying on marketing claims.
Typical dosage used in studies
Skincare products use it at formulated concentrations (often around 0.5–1%); oral dosing is not well established. This is general information from research, not a personal recommendation or a dosing instruction.
Side effects and safety
Ferulic acid is generally well tolerated topically and as a food component; isolated oral supplementation is less studied. As with any supplement, it's sensible to introduce Ferulic Acid on its own, use a trusted brand, and stop if you notice any reaction.
Medication interactions and who should avoid Ferulic Acid

This is general information, not personal medical advice. If you take any medication, are pregnant or breastfeeding, or have a health condition, confirm it's safe to use Ferulic Acid with your doctor or pharmacist first.
