IS TOPICALLY APPLIED GREEN TEA EXTRACT PROTECTIVE AGAINST UV LIGHT SKIN DAMAGE?
Previous studies have suggested that high concentrations of green tea extract are necessary to exert a protective effect against UVB-induced skin damage.
Note: Keratinocytes are the primary cells of the epidermis.
Note: p53 is a transcription factor that helps regulate cell division rates. UV radiation can promote the induction of p53 in skin keratinocytes.
Note: UV radiation often promotes apoptosis (programmed cell death) in skin keratinocytes.
Note: OM24� is a Swiss phytochemical extract that includes concentrated green tea.
Green tea extract reduces induction of p53 and apoptosis in UVB-irradiated human skin independent of transcriptional controls.

The study examined the possible protective effect of green tea extract, applied topically, as a protective agent against UVB skin damage. The investigators concluded that:
"Topical GTE (OM24((R))) reduces UVB-mediated epithelial damage already at low, cosmetically usable concentrations, without tachyphylaxis over 5 weeks, suggesting GTE as suitable everyday photochemopreventive agents."
