Ellagic acid, an antioxidant found in berries, like blueberries or strawberries, is used to prevent skin damage caused by UV rays that are leading to the appearance of wrinkles.

wrinkles preventA topical application of ellagic acid prevents the destruction of collagen and the inflammatory response, which is the main cause of wrinkles, both human skin cells and in mice without hair (especially sensitive products) for continuous exposure to UVB rays sun

The study was conducted by researchers at the Hallym University, South Korea and presented by Ji Young Bae in an Experimental Biology meeting of the American Society of Nutrition in the U.S. city of New Orleans.

Ellagic acid is an antioxidant found in many vegetables and fruits, especially raspberries, strawberries, blueberries and pomegranates, which previous studies had suggested its photoprotective effects.

The UW study found that in the human skin cells ellagic acid works to protect from damage caused by UV rays.

This acid blocks the production of MMP (matrix metalaproteinasa enzymes) that break down collagen in the damaged cells in the skin, and reduces the expression of a molecule involved in inflammation ICAM.

The scientists turned to the young mice (four weeks) and hairless males, which is a variety often used in dermatological studies because of their physiological similarity to human skin.

A dozen of these rodents were exposed for eight weeks at increasing UV-light as the sun-three times a week, starting with a level sufficient to cause redness or burns on human skin.

During the trial, half of the mice received daily applications of ellagic acid on the skin and the rest.

Mice exposed to UV radiation ellagic acid were not developed wrinkles and skin thickening, compared with each other were treated rodents, which showed reduced formation of wrinkles.

In addition, as suggested by studies with human cells, ellagic acid reduces the inflammatory response and secretion of MMP, because of its ability to protect collagen degradation.
