Stem Cells in the Human Skin
Human skin contains two types of stem cells, epithelial skin stem cells which are located in the basal layer of the epidermis and hair bulge stem cells located in hair follicles. Fast regenerating tissue such as the epidermis are particularly dependent on stem cells as only stem cells have the capability to divide and thus to provide new tissue. All stem cells, independently of their origin (plant, animal or human) contain specific epigenetic factors whose function is to preserve the self-renewal capacity of stem cells and maintain the balance of cells within the skin as well as to regenerate damaged tissue.
Skin Stem Cells and Aging
Skin stem cells have a limited life expectancy, intrinsic and extrinsic stress factors affect their functionality. With age, skin stem cells are less active and lower in number, this explains why the depletion of skin stem cells is regarded as the primary cause of skin aging.
PhytoCellTec™ Malus Domestica is the first plant stem cell active ingredient evaluated on human skin stem cells. This unique and revolutionary ingredient is able to protect skin stem cells against premature aging, increasing the longevity of skin stem cells and delaying the deterioration and loss of capacity of skin stem cells to divide and grow new essential cells. It increases the vitality of skin stem cells while combating chronological aging, helping skin stem cells to maintain their characteristics and their capacity to build new tissue for longer while delaying the deterioration of essential skin stem cells.
