In order to avoid the misunderstanding of “barrier repair” for all skin problems, and to let fat people with real skin damage problems understand more about their own skin so that they can better match products. In order to avoid the misunderstanding of “barrier repair” for any skin problem, and to let fat people with real skin damage problems to understand their own skin better so that they can better match the products, this time we will systematically explain what is “barrier repair” to repair? And how to repair it?
Before we can understand how to repair the barrier, we need to know what is the barrier?
1. Understanding the “skin barrier”
The skin barrier includes physical barrier, pigment barrier, nerve barrier, and immune barrier. What we usually call “barrier repair” generally refers to the “physical barrier”, which is also known as the “stratum corneum”.
The physical barrier is a unique brick wall structure. To build a wall, you need bricks + cement; if there are only bricks, it will fall down when you push it, and if there is only cement, it cannot be built into a wall at all.
Bricks refer to keratin cells in the stratum corneum, one keratin cell is equal to one brick; keratin cells are inanimate dead cells, they make up the bricks in the brick wall structure. The layers of “bricks”, together with the “cement”, form a solid physical barrier.
