A Strong Shield: The Skin Barrier

The skin barrier is the epidermal layer that functions as a protective barrier against external factors. It prevents the entry of environmental agents, limits water loss, and serves essential functions in protecting skin tissues. The skin barrier is formed by cells, lipids (fats), and natural moisturizers found in different layers of the epidermis. These components enable the healthy functioning of the skin. Here are the primary functions of the skin barrier: 1. The skin barrier prevents microorganisms, toxins, chemicals, and other environmental factors from entering the skin, thereby safeguarding the body from external threats. 2. The skin barrier retains moisture on the skin's surface and limits its evaporation, helping to maintain the skin's moisture balance. 3. The skin barrier assists in maintaining cellular structures and tissue integrity, aiding wound healing and providing resistance against potential external damage. 4. The skin barrier regulates the activity of immune cells, enhances the effectiveness of the immune system by preventing the entry of harmful microorganisms into the body. 5. A balanced production of lipids and natural moisturizers is crucial for the healthy functioning of the skin barrier. However, external factors, improper skincare products, frequent washing, and similar factors can weaken the skin barrier. This can lead to skin problems, irritation, dryness, and sensitivity. 6. If sensitivity occurs in the skin barrier, dryness, flaking, irritation, itching, acne, or red rashes may be observed. Maintaining proper skincare is important for the health of the skin barrier. Steps such as moisturization, using appropriate cleansing products, and sun protection can support the skin barrier.
