Grapes protect against UV

Compounds found in grapes may protect skin cells from the sun's ultraviolet radiation, say researchers who support the use of grapes or derivatives in sun protection products.

Some compounds found in grapes help to protect skin cells from the sun's ultraviolet radiation, according to a study by researchers from the University of Barcelona and the CSIC (Spanish National Research Council). The study supports the use of grapes or grape derivatives in sun protection products.

A group of scientists from the University of Barcelona and the CSIC have shown that some polyphenolic substances extracted from grapes (flavourings) can reduce the formation of ROSs in human epidermis cells that have been exposed to long-wave (UVA) and medium-wave (UVB) ultraviolet radiation. The study, carried out in vitro in the laboratory, has been published in the Journal of Agricultural and Food Chemistry.
