Naolys, a French company represented in Italy by Carlo Sessa S.p.A. and specialized in active plant cell culture, proposed an innovative complex called Power Extension [ HSB + R], that consists of native cells of Hibiscus syriacus Blue Bird. It contains not only the active molecules of the plant itself, but also molecules of natural Rutin to obtain a higher activity of the complex thus formed; Power Extension [ HSB + R], the first complex plant cell dedicated to mature skin, strengthens metabolism during cellular aging thanks to a control activity of the proteasome – especially in senescent keratinocytes – and an increase of 43 % of the release of CO2. As a result, it generates a global anti-aging effect, clinically proven by a decrease of the surface of wrinkles by 27% in 28 days. All tests were performed with a concentration of 0.1 % of the complex powder. Power Extension [ HSB + R] is hypoallergenic, preservative free and it can be used in any formulation, from skincare to make-up.
