Vitamin E Oil Rejuvinates
Vitamins are a natural constituent of human skin and are part of a system of antioxidants that protect the skin from oxidative stress. There has been an increased interest in the use of natural antioxidants such as vitamins to help restore dermal antioxidant activity. Vitamins A, C, E, and B3 have been shown to have potent antioxidant and anti-inflammatory properties, but to achieve optimal effectiveness, products must be delivered in appropriate formulations. All biteglow teeth whitening kits come packaged with Vitamin E loaded cue tips.

biteglow uses a mild concentration of hydrogen peroxide to whiten your teeth. This reduces the risk of damage to your sensitive gums and lips. In the event you accidentally overload your trays with whitening gel or your gums/lips are exposed to the gel repeatedly for extended periods they may become irritated. Vitamin E has been proven to reduce this irritation.

In extreme cases of irritation, treatment should be ceased and your gums/lips will heal by themselves.
