So, the question arises, what exactly is the skin barrier? Here, let professional dermatologists take you to recognize! Skin barrier system – the natural defender of human skin The surface layer of each person’s skin actually has a layer of natural skin barrier system, which consists of the stratum corneum and sebaceous membrane of the human epidermis. The stratum corneum is the outermost part of the epidermis, the skin moisture retention by the skin stratum corneum water content, that is to say, our skin is dry, depends on this layer. In the stratum corneum, keratinocytes and intercellular lipids are arranged in a brick-wall-like structure, forming a stable skin structure that protects the skin’s barrier function, effectively preventing excessive evaporation of water from the body while preventing bacteria or foreign objects from invading the body. In general, the skin barrier consists of the top layer of the skin on the entire body, which is the surface of the skin visible to the naked eye. Its function is to keep the skin moisturized, smooth and shielded from harmful substances. Most skin problems stem from a damaged skin barrier Undamaged, healthy skin looks and feels smooth, soft, plump, and definitely not dry. But when the skin barrier is damaged, the skin becomes dry, rough, and dull as if dehydrated. Closed air-conditioned environments, frequent bathing, too much time in the shower or too high a water temperature …… all kinds of problems can cause damage to the skin barrier. When the barrier is damaged, the skin will quickly launch self-repair, but with the passage of time, the skin’s self-repair speed will gradually slow down, once the skin barrier is damaged, the internal can not lock moisture, external can not resist microbial and chemical attack, resulting in a series of vicious circle. The skin is more and more dry, produce all kinds of discomfort. Therefore, winter itchy skin, especially infant eczema, elderly scratching, in the clinic also often need to follow the doctor’s advice, do not take a bath or the correct bathing (choose mild non-irritating bath products).
