Emollients are substances that soften and moisturize the skin and decrease itching and flaking. Dry skin is caused by a loss of water in the upper layer of the skin.
Emollients/moisturizers work by forming an oily layer on the top of the skin that traps water in the skin. This helps the dead skin cells fall off, helps the skin keep in more water, and leaves the skin feeling smoother and softer.
