Extensive studies have shown that PhytoCellTec™ Solar Vitis reliably protects epidermal stem cells from UV stress and thus from skin aging caused by light. PhytoCellTec™ Solar Vitis increases the vitality and efficiency of all essential skin cells and improves the skin's resistance.
The use of plant stem cells protects the most important skin cells, namely its stem cells, thus delaying skin aging. PhytoCellTec™ Solar Vitis protects the skin from chronological and light-induced aging, extending skin cells' vitality and keeping the skin's appearance young and beautiful longer.
Improves the vitality of stem cells
Cultures of epidermal stem cells were treated with different concentrations of PhytoCellTec™ Solar Vitis and their colony-forming efficiency was measured. The research demonstrated that PhytoCellTec™ Solar Vitis clearly has a positive effect on stem cell characteristics. (see chart)
Protects epidermal stem cells from UV stress
Cultures of epidermal stem cells were treated with PhytoCellTec™ Solar Vitis, while others were left untreated. The cultures were exposed to UVA and UVB rays, and the colony-forming efficiency (CFE) of the stem cells was then measured. The results showed that UV radiation strongly reduced cells' colony-forming efficiency (-58%). Treatment with PhytoCellTec™ Solar Vitis improved the colony-forming ability of the stem cells, and the cells' vitality was not impaired even after exposure to UV radiation. (see chart)
