Nourishment and protection of the skin: structure and functions
The skin, despite appearing delicate and sensitive, plays a vital role in protecting the body from harmful mechanical, chemical, and biological factors. It also plays a crucial role in maintaining the balance between the external and internal environments and regulating body temperature. The skin, measuring just 5 mm at its thickest, is composed of three layers: the epidermis, the dermis, and the subcutis. The outermost layer of the epidermis, called the stratum corneum, contains lipids and keratinocytes responsible for nourishing the skin and retaining moisture. Lipids such as ceramides and phospholipids are also responsible for maintaining the correct pH and skin respiration. The dermis contains collagen fibers that contribute to skin elasticity and firmness. The skin also contains sebaceous and sweat glands, receptors that respond to cold and heat, and hair-like blood vessels. Their proper functioning is essential for the good condition of the skin and its attractive appearance. Properly nourished and hydrated skin can perform all its functions even under extreme conditions. However, problems can arise when the skin does not receive all the necessary nutrients and substances. In such cases, spots, discoloration, and rashes may appear on the skin surface.
