The skin is the largest organ in the human body and is continually confronted with environmental and other stresses (frequent showering and/or hand-washing, harsh washing products or care products). The natural moisture balance of the skin is brought out of balance and the skin becomes more and more dry and sensitive. The top layer of the skin (epidermis) is responsible for the regulation of this balance. It represents the protection against the environment. the protective function is at risk when this layer of the skin is damaged. Free radicals are part of particular immune cells are help in the defense against bacteria and viruses. A surplus of free radicals, however, damages cells and can bring about premature aging of the skin. Therefore humans have developed a skin protection system, in particular to keep aggressive oxygen radicals under control. Normally a natural balance exists between free radicals and the mechanism which inhibtis their dispersion throughout the skin.
