Your DSPW Skin is characterized by dehydration. Why does this occur?
DSPW Skin types have a defective skin barrier. This means that water evaporates off of the skin – leading to dehydration.
What is the “skin barrier”?
The skin barrier is a layer of lipids (fats) that surround the skin cells (keratinocytes).  These lipids are made up of cholesterol, fatty acids and ceramides that surround the skin cells in multiple layers.

These layers surround each keratinocyte.
The lipids fit together like puzzle pieces to form a complex 3D structure whose function is to prevent water from evaporating off of the skin. In the drawing below purple = cholesterol, orange = fatty acids and green = ceramides.
