What is Elastin?

   Elastin gives our skin the ability to stretch and recoil
   The sun damages this tissue
   The damaged tissue cannot 'bounce back' as healthy tissue does
         

Elastin Makes Skin 'Stretchy'

Elastin fibers are structural proteins found throughout our bodies that allow organs to stretch and recoil, thereby maintaining their shape. As the elastin in our skin is exposed to the sun it becomes progressively damaged, and over time the healthy elastic tissue is replaced with damaged, degraded elastin. Healthy, undamaged skin is usually 80% collagen and 4% elastic fiber mesh network. Sun-damaged skin can grow to be as much as 80% abnormal elastic fibers. These damaged fibers clump and behave as a rubber tire compared with a strong, elastic rubber band. Whereas undamaged skin has a great deal of elasticity, sun-damaged skin is much more prone to wrinkles and is very inelastic.

Skin Doesn't Wrinkle from Use

Consider any child you know. They move their faces all day and have no wrinkles. Wrinkling is not caused by facial muscles 'creasing' our skin. If our skin wasn't damaged it would bounce back into place just like a child's does. But skin that is subjected to years of the sun's damaging rays has elastin tissue which malfunctions and can no longer bounce back into place. Those wrinkles you see on your forehead are the result of our facial muscles interacting with our damaged skin. Healthy skin 'snaps back' into place, damaged skin doesn't.
