Intolerant and easily irritated skin

The causes of skin intolerance

There are two phenomena that together explain the excessive reaction found in easily irritated skin:

• An alteration in the skin’s barrier function

The stratum corneum, the outermost layer of the epidermis, can no longer act as a protective barrier because the lipids that “weld” its cells together are altered. The area between the epidermis and dermis is also weakened. As a result, the skin becomes more permeable and allows potentially irritating substances to enter the body. It is also more prone to dehydration.

• A lower level of skin tolerance

At the same time, the skin reacts excessively to any aggression, even if it is harmless, and that reaction results in inflammation.
