Stem cells are cells that are found in most, if not all, multicellular organisms. They are characterised by their capacity for self-renewal through mitotic cell division and differentiation into a wide range of specialised cell types.

They protect and strengthen the dermo-epidermal junction. They restructure the skin by regulating keratogenesis and strengthening the extracellular matrix. Thanks to their infinite regenerative capacity, stem cells help stimulate the synthesis of collagen and elastin in the extracellular matrix, accelerating the cell renewal process and reducing wrinkles and expression lines.
