Ferulic Acid, extracted from Rice Bran Oil, is one of the most powerful natural anti-oxidants. from rice bran oil, Many plants contain Ferulic acid, which plays a key role in the plants self preservation mechanism, re-enforcing it’s cellular wall strength and protecting it from microbial damage as well as sun damage.
Ferulic acid is also said to be an effective antioxidant and helps extend the activity of other anti-oxidants like vitamin C. In particular the combination of Vitamins C, and E, were shown to double their photo protective capacity on the skin. It is well known that Vitamin C is very problematic in skin care due to it’s highly oxidative state. There are several factors that must be controlled for topical Vitamin C to be effective. One of those factors is stabilization once it’s exposed to air, or moisture, where Vitamin C quickly oxidizes. Ferulic Acid has been shown to do just that. Ferulic Acid, combined at 0.8%, with Vitamin C works to stabilize the Vitamin C, preventing the oxidation.
For effective delivery of Vitamin C into the tissues it is important to control several other variables: pH must be acidic and less then 3.5, stabilization against oxidation in the presence of air and moisture, the most effective method known, at this time, is the addition of other anti-oxidants, the combination proven the most successful being the addition of 1.0% Vitamin E and 0.8% Ferulic Acid … in the study that evaluated the effectiveness of topical anti-oxidants, for photo protective activity, it was demonstrated that the combination of 15% ascorbic acid and 1% Vitamin E increased the skin’s photo protective benefits by 4 times the normal level, which was doubled to 8 times with the addition of 0.5% Ferulic Acid, the famous C+E Ferulic Serum.
