Definitions

• the present invention relates to cosmetic and / or dermatological preparations for decorative skin care.
• the skin is the largest human organ. Among its many functions (for example for heat regulation and as a sensory organ), the most important is the barrier function that prevents the skin (and ultimately the entire organism) from drying out. At the same time, the skin acts as a protective device against the penetration and absorption of substances coming from outside. This barrier function is brought about by the epidermis, which as the outermost layer forms the actual protective cover against the environment. At around a tenth of the total thickness, it is also the thinnest layer of the skin.
• the task of cosmetic skin care is to strengthen or strengthen the natural function of the skin as a barrier against environmental influences (e.g. dirt, chemicals, microorganisms) and against the loss of the body's own substances (e.g. water, natural fats, eiectroiyte) restore.
