Skin Barrier

Posted on by Beste Gürkan

 The term “Skin Barrier” has started to be mentioned frequently in many articles, various journals and websites recently. The fact that the topic of skin barrier is being mentioned on almost every platform and so frequently, naturally, questions arise in our minds as to whether it is an exaggeration or is it really an important issue. The role of the skin barrier in skin health is enormous. There are numerous clinical studies and studies on this.

 In order to understand the importance of the skin barrier, we must first start by explaining what is meant by Skin Barrier.

 The primary task of the skin barrier is to keep water in our skin and body, to prevent water loss and to prevent our internal organs from drying out. Without this protection mechanism of our body, we cannot continue our normal life activities and everything from the largest organs in our body to our smallest cells dries up, resulting in death.

Another task of the skin barrier is to keep harmful factors away from our body. With all the chemicals, pathogenic microorganisms and sun rays we are exposed to every day, the task of our skin barrier is to prevent them from entering our body.

 The skin barrier, which we can also define as the physical barrier, is the uppermost part of the Stratum Corneum, which is the top layer of the Epidermis, and basically consists of cells rich in protein and adipose tissue. If our skin surface has a smooth, soft and full structure, it means we have a healthy skin. Conversely: if our skin looks dry, rough, dull, flaky and dehydrated, we have damaged and unhealthy skin. Even the smallest changes in the epidermis and the oil composition of the epidermis cause damage to the skin barrier.

This is not a matter of aesthetic appearance in order to avoid misunderstanding. It is vital that the skin barrier is healthy. When the skin barrier is damaged, it becomes difficult to get rid of skin problems such as wrinkles, pre-acne rashes, acne, dry skin, and skin sensitivity. No matter how hard we try to get rid of these problems, the first thing to do is to repair the damage in the skin barrier.

 It has been determined that inflammatory skin diseases such as Psoriasis and Atopic Deratitis can also occur as a result of weak skin barrier functions.

 What damages the Skin Barrier?

 The barrier function of our skin is weakened and damaged as a result of scraping away the oils found in the natural structure of our skin with hard surface cleaners, surfactants, organic solvents such as ethyl alcohol, and detergents.

At the same time, allergens (essential and essential oils), irritants, chemical or physical trauma can trigger barrier damage by causing inflammation in the epidermis.

The best treatment is to avoid all these damaging factors.

 The health of the Skin Barrier içto avoid:

  • The use of very hot or very cold water should be avoided, both of which irritate the skin.
  • Use of excessive amount of scrub should be avoided as it may damage the skin surface. For the purpose of deep cleaning, scrubs containing particles with smooth surface and 1-2 times a week should be preferred. Products containing uneven particles can scratch the surface of the skin, causing inflammation.
  • It is necessary to avoid using skin cleansers that contain chemicals such as Soap, Sulfates (such as SLES, SLS, ALS), Ethyl Alcohol, dry the skin and remove all skin oil.
  • Do not use products that irritate the skin.
  • The use of products containing very high levels of actives such as AHA, BHA, Retinol and anti-acne drugs should not be overdone. These products should be used in a controlled manner and concentrations that do not cause irritation on the skin should be preferred.
  • You should not go out into the sun without applying sunscreen with a broad spectrum (with UVA – UVB protection) and avoid exposure to direct sun rays. Sun rays cause weakening of the immune system and all kinds of skin damage.
