As the afternoon sun warms your body, you feel even better.
After a while, the heat from the sun becomes intense. You start to sweat, and your skin feels like it’s burning. Finally, the heat becomes too intense. So, you jump to your feet and sprint across the sand to the ocean, jumping into the water. You feel relieved as the cool water washes over you.
That sun worshipping experience was what you did to get a tan. And sun tanning can age you.
In fact, sun exposure is a major cause of skin aging. There’s even a word for this type of aging — photoaging.
According to the American Academy of Dermatology (AAD), photoaging is a type of premature aging.1 AAD says it can give skin a wrinkled, leathery appearance.
Thankfully, scientists have found that one of your favorite foods can help prevent the skin damage caused by the sun. Several new studies show that grape seed proanthocyanidins — compounds from grape seed extract — interfere with photoaging.
One study shows that in the photoaging process, the sun’s ultraviolet (UV) radiation causes skin inflammation, damages skin cells by overproducing specific types of molecules, and damages DNA in skin cells. 2
The authors say that in mouse skin, grape seed proanthocyanidins reduce several types of inflammation caused by ultraviolet radiation: erythema (sunburn) and edema (swelling caused by fluid build-up).
Another study found that dietary grape seed proanthocyanidins could interfere with the creation of reactive oxygen species (molecules containing oxygen) in the outer layer of skin.3
The authors exposed mouse skin to the sun’s ultraviolet B (UVB) radiation. They concluded that the grape seed compound could prevent powerful molecules known as reactive oxygen species (ROS) from being produced excessively and from damaging cells.
Another study found that dietary grape seed proanthocyanidins could enhance the repair of skin cell DNA that was damaged by ultraviolet B (UVB) radiation.4
In addition to grape seed proanthocyanidins, there are several other substances that may help protect your skin from the damaging effects of the sun’s ultraviolet radiation:
- Green tea antioxidants 5
- Resveratrol, an antioxidant from grapes and red wine 6
Bio-Oxidate Defense™ promotes cell integrity and anti-aging with natural antioxidants to discourage cell damage due to lifestyle factors. Bio-Oxidate Defense contains green tea, resveratrol, and grape seed extract.
