Flaky facial skin: How can I recognize dry skin? Dry skin is often scaly and rough on its surface. While a healthy skin barrier offers protection against environmental influences and regulates the skin's moisture balance, a lack of oil and moisture can cause a disturbed skin barrier. Important for the skin barrier are an intact horn layer and the so-called acid mantle, a water-lipid film consisting of sweat, sebum, electrolytes, urea, various acids, peptides and fatty acids, among others, which is the basic condition for a balanced microflora of the skin. If the skin barrier is disturbed, the skin loses moisture and fat. The skin becomes dry and reacts more sensitively to external influences. Dry skin also loses elasticity more quickly and increased wrinkle formation is the result. In addition, feelings of tension and itching can arise, and in the case of very dry skin also slight redness and cracks. Regular skin care is therefore indispensable, especially for dry skin. Replenishing creams offer dry skin protection and can help it to regenerate.
