1.What is the skin barrier?
The outermost layer of the skin is called the stratum corneum, which is composed of 20 layers of flat, intertwined keratinocytes. The keratinocytes are as tough as "bricks", and lipids like "mortar" in which the keratinocytes are closely connected to each other to form a "brick wall structure". There is also a protective film (water) composed of sweat and sebum on its surface. Lipid membrane, which together constitute the skin barrier. The skin barrier can lock skin moisture and oil, and resist the invasion of various skin surface bacteria, which plays a very important role in protecting human health.
2. Skin diseases and skin barrier
There are many kinds of skin diseases. Many skin diseases are prone to recurrence, but it is difficult to find the specific cause of the disease. Common skin redness, itching, dryness and other "skin allergies" manifestations, it is actually difficult to find specific "allergenic". However, a common cause of these skin diseases can be found-"skin barrier damage", that is, the skin surface loses its normal protective function and there is loss of skin moisture, resulting in dryness, desquamation or itching of the skin. At the same, bacteria on the surface of the skin easily enter the skin through the damaged skin barrier, thereby further triggering skin inflammation. Therefore, damage to the skin barrier is not only a manifestation of many skin diseases, but may also be an important reason why skin diseases are prone to recurrence.

This means that the skin surface use moisturizing skin care products to supplement the "hydrolipid film" on the skin surface and the "mortar" between the cells. The "brick wall structure" that reinforces the skin surface.
Skin Barrier Repair's moisturizing skin care products should have the following 3 basic ingredients:
①Materials for moisture absorbents, including glycerin, urea, etc., can absorb water from the environment and replenish the water lost from the stratum corneum.
②The sealant raw materials, such as petrolatum, avocado oil, etc., can form a thin hydrophobic oil film on the skin surface, which has the effect of strengthening the skin barrier.
