Our skin is kept healthy by a constant turnover, with dying skin cells being shed and replaced by new cells. The process is maintained by 'progenitor' cells -- the progeny of stem cells -- that divide and 'differentiate' into fully-functional skin cells to replenish dying skin. These cells are in...
