F-XFC formula is skin booster with more than 63 active ingredients. The main function of the product is to provide metabolites to the cells to stimulate their metabolism (production of energy, proteins and cellular growth). This exclusive blend contains all the nutrients and the molecules involved in the Krebs cycle. These nutrients are essentials for the production of energy (ATP) and boost the skin functions. As there are no blood vessels in the epidermis, the cells are nourished exclusively by passive diffusion of plasma from the dermis. While ageing, the skin is in lack of nutrients and oxygen due to a less performing circulatory system.
