Abstract
The effect of plant polyphenolic compounds (PPs) on the viability of human keratinocytes exposed to ultraviolet (UV) radiation of range C (UVС) and the number of single-stranded DNA breaks in the nuclei of these cells was studied. The experimental data obtained indicate that, along with the cytoprotective effect, the addition of silybin and acacetin immediately after the UVC exposure leads to a significant decrease in the number of single-stranded DNA breaks in the nuclei of HaCaT keratinocytes 2 and 5 h after exposure. It was concluded that PPs are able to reduce the destructive effect of UV radiation on skin cells, reducing the number of genetic damage.
