A study carried out by researchers from the CSIC and the University of Barcelona has shown that some grape compounds contribute to skin cells being protected against the ultraviolet rays of the sun and can decrease the damage that occurs in cells of the skin that has been exposed to solar radiation.

Ultraviolet rays are the main environmental risk factor to develop skin diseases, and originate from serious pathologies such as skin cancer, to sunburn and erythema, in addition to accelerating the aging of the dermis and epidermis. Radiation damages the skin by activating reactive oxygen species (ROS), and triggering certain reactions that drive the death of cells.

The data obtained in this study reveal that certain polyphenolic substances obtained from grapes (flavanols) have the ability to inhibit the generation of ROS in cells of the epidermis exposed to ultraviolet radiation of medium (UVB) and long wave (UVA). The experiment was carried out in the laboratory in vitro, and its results have been published in Journal of Agricultural and Food Chemistry.

The researchers believe that the results of the study should be taken into account in order to develop new photoprotectors

Researchers believe that clinical pharmacology, which studies various plant polyphenolic substances in order to develop new products that serve as cutaneous photoprotection, must take into account these results to evaluate the possibility of incorporating these compounds of the grape to the sunscreen creams .

Although at present there are already cosmetics that include in their composition substances from the grape, until now their way of acting on the cells was not known.
