CAUSES OF DRY SKIN

Owing to stress, a poor lifestyle, too much UV exposure, negative environmental effects or weather conditions, but also to wrong, overly aggressive skin cleansing, the general ageing process, and many other causes, skin loses its protective function. Therefore, increased transepidermal water loss caused by this leads to rough, flaky skin. Skin declines in suppleness, it feels tight, and reacts more sensitively.

INTRODUCTION THE SKIN OUR LARGEST ORGAN

Above all, the skin is our protection against all external influences. In an adult, it measures about 1.5 to 2 square meters and contains about 600,000 cells per square meter. The skin renews itself regularly. Within an average of 28 days, the skin surface has completely renewed. The skin keeps our body temperature constant at about 37 degrees.

It releases excess heat to the outside and causes evaporative cooling through sweating. At low outside temperatures, it conducts the remaining heat inwards via the blood vessels to protect vital organs.

THE HYDROLIPID BALANCE

The natural skin barrier consists of 15-20 layers of corneocytes, which are embedded in a lipophilic intercellular substance in a usually regular, columnar arrangement in the stratum corneum of the skin.

The size, number and arrangement of corneocytes influences the physical barrier function of the skin. It depends on the water content of the corneocytes, the age and the season.

The intercellular lipid layer prevents the evaporation of water and is mainly responsible for the chemical barrier function of the skin. It contains keratinosomes (so called Odland bodies), which consist of ceramides, sterols and free fatty acids and form broad, parallel, lamellar lipid layers that seal the intercellular space between the keratinocytes. The acid mantle is a thin hydrolipidic film consisting of sebum and sweat formed by sebaceous glands and, depending on the body area, has a pH value of 4.0 5.8. A too high pH value can lead to an increased degradation of barrier lipids and a reduced infection defense of the skin.
