The skin barrier: bricks and mortar
The outermost layer of the skin is often compared to a wall. The skin cells are the bricks, and between them lies a mortar of lipids: ceramides, cholesterol and fatty acids.
When the mortar is intact, the skin holds on to its moisture and withstands stress from outside. When it thins, water evaporates faster and the skin becomes tight, rough and more easily irritated.
That is why caring for dry skin is less about a single miracle ingredient and more about supporting the wall – every day.
