Ferulic AcidBenefits, how to use & safety
The stabiliser that doubles your vitamin C's staying power.
What is Ferulic Acid?
Ferulic acid is a plant antioxidant found in rice bran, wheat and many fruits. In skincare, it is best known for stabilising vitamin C and E, extending their shelf life and effectiveness while adding its own protective benefits.
How it works
Ferulic acid neutralises free radicals and helps keep vitamin C in its active state. Research showed that combining vitamin C, vitamin E and ferulic acid roughly doubled photoprotection compared with vitamin C alone, which is why this trio became a classic.

How to use it

Safety & side effects
Ferulic acid is well tolerated. Irritation comes mostly from the low pH of the vitamin C base in the product, not from ferulic acid itself.
Frequently asked
Do I need ferulic acid in my vitamin C serum?
It is not essential, but it improves stability and protection, so a vitamin C serum with it is usually a better formula.
Can I use ferulic acid alone?
Yes, but its biggest benefit is as a stabiliser and booster for other antioxidants.
Does ferulic acid brighten skin?
Indirectly. It protects against oxidative damage that contributes to dullness and pigmentation.
