Skin barrier and thermal spring water

What happens if this barrier no longer does its job?

When the skin barrier is weakened, its protective role is weakened and it is no longer able to maintain adequate moisture levels. In addition, inflammation of the skin may occur due to a reaction of the cutaneous sensory neurons, which are responsible for hypersensitivity.

The skin then reacts to everything. It seems distraught. It has a lower tolerance threshold and reacts abnormally to very mild stresses such as temperature variations, pollution, stress and emotions. In concrete terms, this sensitivity manifests itself in the form of recurrent redness and unpleasant sensations such as tingling, tightness or hot flushes that your usual moisturising cosmetic products are unable to soothe.
