Stem cells are extremely beneficial in the natural process of healing and regeneration. They are found in all living things and have the ability to turn into all different kinds of cells and help the body regenerate. Your skin is already packed with stem cells. As you age, you start to lose them. By the time you hit 50, you've lost about 98 percent of them. When you're young, the average turnover for your skin is about 25 to 30 days. When you get older, the production slows down and the turnover can take up to 60 days. When it's exposed to the elements longer, it loses that youthful vibrant look.
Stem-cell skin care products don't contain actual stem cells, but rather the growth factors and proteins that the youthful cells secrete. Growth factors play a role in cell division, the growth of new cells, and the production of collagen and elastin. Proteins regulate that stem-cell division. When applied to your skin, these two components help firm wrinkles and slow the development of new lines. The cocktail of proteins and growth factors that are harvested from the actual stem cells themselves signal your own cells to produce more collagen and elastin and ultimately fire up the rejuvenation process.
