Dry skin results from lack of water in the outer layer of skin cells (the stratum corneum). When this layer becomes dehydrated, it loses its flexibility and becomes cracked, scaly, and sometimes itchy. The stratum corneum contains natural water-holding substances that retain water seeping up from the deeper layers of the skin, and water is also normally retained in the stratum corneum by a surface film of natural oil (sebum) and broken-down skin cells, which slow down evaporation of water from the skin surface.<unk>  works by increasing that layer of oil.
