In the skin, appearance and functionality are closely intertwined. The skin barrier contributes in complex ways to beauty and to the health of the skin and entire body.
A dysfunctional skin barrier contributes to:
An intact skin barrier helps maintain healthy-looking, plump, elastic, smooth, evenly colored skin:
Some of the things that our skin barrier helps protect us from:
Potentially harmful chemicals may enter the body through a “leaky” or damaged skin barrier. But even a healthy skin barrier is not impervious, which is why it’s important to use clean products that have been screened for possibly toxic ingredients. Ingredients from chemical sunscreens are have been found inside the body and in the blood.
Some of the things our skin barrier helps retain in the body:
Keeping water inside the body is about more than keeping skin plump. Without a functional skin barrier, for example when burns are extensive, water loss could be fatal. Additionally, adequate water keeps skin cells healthy and functioning. In research, a common way to assess how well the skin barrier is functioning is to measure loss of water through the skin— trans-epidermal water loss (TEWL).
