Antimicrobial, Antioxidant

Ferulic Acid is a plant based antioxidant. By fighting free-radicals, ferulic acid can help reduce the formation of fine lines and hyperpigmentation.

When used with Vitamin C, Ferulic Acid has shown to prevent Vitamin C from breaking down. In other words, it acts as a stabilizer.

Ferulic Acid is sometimes used to preserve food. Foods containing Ferulic Acid include: oats, rice, eggplant, citrus.

In medicine, Ferulic Acid is being studied for helping with diabetes, Alzheimer's, and cardiovascular diseases.

As a redhead I’ve got some pretty reactive skin, but vitamin C is a must. I’ve tried vitamin C serums with regular ascorbic acid but they were too harsh and irritating, even using once a week. This serum contains a stabilized form of vitamin C that is so gentle I can use it daily without any problems. When I run out, I can immediately tell a difference! My skin loves this stuff. I hope they never Show more

This works really well for me. It feels like a bit sticky at first but it absorbs well. You only have to use a little bit otherwise it can be a bit drying; I have sensitive and eczema prone skin.
