At a young age, the skin is characterized by its evenness. So she is neither adorned by impurities nor is she plagued by blackheads or the like. Typical of dry skin, however, is the formation of fine skin flakes that roll off the skin. The lack of moisture in the skin also often leads to a feeling of tightness on the skin. Due to its thin surface, the skin remains more susceptible to infections and reacts more strongly to environmental influences. This can also promote premature aging of the skin in the form of wrinkles. First wrinkles around eyes, neck and mouth can appear already at the age of 20. The culprit of dry skin, in contrast to impure skin, is an underproduction of the sebaceous glands. These therefore produce too little fat and water, so that the skin is not sufficiently supplied and is more susceptible to external influences such as UV radiation. Weather-related factors can also dry out your skin. Due to the transpiration process in the summer heat, the skin loses fluid and dries out. The use of air conditioning can further reinforce this process. But even in winter, your skin is at risk of drying out. If the thermometer falls below a temperature of 8°C , the sebaceous glands no longer produce fat. Moreover, since your skin hardly transports any fluid to the outside via the transpiration process in winter, this throws your skin’s water balance off track. As a result, the skin dries out.
