Antioxidant That Retards Wrinkles Discovered
September 22, 2007
A plant-based antioxidant that fights wrinkles in your skin has been isolated by a researcher at The Hebrew University of Jerusalem.
Antioxidants help to fight free radicals, which can break down many body tissues when present in excessive amounts. In the skin, free radicals from aging or exposure to ultraviolet light cause a breakdown of collagen and elastin fibers, leading to a loss of skin elasticity and wrinkles.
The antioxidant developed at The Hebrew University delays skin aging by inhibiting the breakdown of collagen fibers in the skin.
When the antioxidant was applied to skin cells from mice that had been exposed to the sun, the cells showed no significant increase in free radical levels. However, cells that were exposed to the sun but did not receive the antioxidant had a rise in free radicals, causing wrinkles.
The newly isolated antioxidant differs from other anti-aging antioxidants on the market in that it is able to withstand high temperatures and does not oxidize easily. This means it will remain effective longer than other antioxidants that oxidize quickly.
The researcher hopes to develop a new generation of cosmetic products that will be effective against wrinkles, including those at deeper levels of the skin.
The plant source of the antioxidant has not been revealed because the research is still being patented.
