Your skin has the ability to naturally activate its own defense system against UVB radiation. To do this it requires antioxidants within your skin to coordinate an optimal response. Antioxidants such as lycopene, ECGC in green tea, and the tocotrienol form of vitamin E have all been shown to help skin.

The most recent study on this subject shows that gamma tocotrienol,1 but not plain vitamin E (d alpha tocopherol), is able to regulate gene signals in skin to reduce damage caused by UVB radiation.

Researchers showed that gamma tocotrienol reduced multiple inflammatory signals following UVB radiation exposure, including a reduction in COX-2, interleukin 1beta, IL-6, and monocyte chemotactic protein-1, in both hairless mice and human skin cells. Further testing revealed that gamma tocotrienol regulated fundamental gene signals in response to UVB radiation which were able to prevent the typical damage seen from UVB exposure.

When individuals take antioxidants like gamma tocotrienol on a regular basis, it accumulates in cell membranes and the skin, where it can help you enjoy the sun with less risk of adverse effects from UVB radiation. Unlike abnormal sunscreen chemicals, this is your body’s natural and normal way of enabling you to be in the sun with less risk to your health.
