In the skin, cells are constantly regenerating and synthesizing the necessary extracellular matrix elements, which are responsible for keeping the tissues in good working order and provide the epidermis with its body barrier properties. These hundreds of thousands cells that make up the epidermis descend from just a few hundred super cells that produce them traumatisms (cuts, burns,…). This fact has a crucial impact on the skin’s appearance, which accumulates small traumatisms as signs of premature ageing: wrinkles, flaccid skin, lack of elasticity, blemishes, dull complexion.

The stem cells have a special metabolism and special nutrients are required to look after  on a daily basis, and these are the skin’s adult  them. Recent genetic engineering studies stem cells
