Dry skin is thin skin, susceptible to irritation, flaking and other uncomfortable symptoms for sufferers.
This type of skin is a consequence of low sebaceous gland activity. As a consequence, the skin loses some of its protective capacity and external irritants can penetrate deeper into the skin.
The surface of the skin is naturally protected against external aggressions by the hydrolipidic film, made up of water and lipids. When an anomaly occurs, in addition to the discomfort it usually causes, it can jeopardize its protective function.
