Skin is tough, taking constant punishment from the elements and us. New cells that grow up from below push older skin cells to the top. When old cells reach the top, they become wider and flatter by all of our activity and eventually fall discarded from our bodies. Every minute 30,000-40,000 dead skin cells fall from your body. Your body has a completely new layer of skin cells in approximately one months time.
Skin contains pigments called melanin.
The more melanin in your skin, the darker your color, less melanin means less color. Sitting outside in the sunshine or in a tanning bed can cause more melanin to be manufactured in your skin cells resulting in a suntan or sunburn. As an adult, you may have more than 20 square feet of skin. Inc. All Rights Reserved.
