Our body is protected from external influences by the skin, which is the largest organ of the human body. Moreover, it is the entrance gate of the whole body. It regulates the supply and excretion of large amounts of substances in the body and its proper functioning is ensured if its surface layer contains sufficient water. Otherwise, the skin is dry, which affects a number of factors. These might be caused, for example, by an inadequate drinking regime, hectic lifestyle, staying in air-conditioned rooms, excessive sunbathing, as well as using cosmetics whose inadequate composition and application can dry the top layer of the skin. To overcome this, you should pay extra attention to proper skin hydration, which begins with basic hygiene.
