What is the stratum corneum? How to increase the thickness of the stratum corneum

The stratum corneum is the outermost layer of the skin. It can resist the invasion of strong acids, strong alkalis and even pathogenic microorganisms. It is equivalent to forming a physical barrier on the surface of the skin to prevent the evaporation of body water. In addition, the stratum corneum also has the function of resisting ultraviolet rays. Therefore, we should not remove it frequently, but vigorously protect the stratum corneum. So how to increase the thickness of the stratum corneum? Are you interested in knowing?

What is the stratum corneum

The stratum corneum itself is the cell of our epidermis, which slowly migrates from the basal layer to the outermost layer of the skin. During the migration process, the cell nucleus shrinks, the cell nucleus disappears, and keratinization occurs. Therefore, the previous concept is that it is a dead skin and should be removed. But in fact, the stratum corneum is very helpful to the skin. The stratum corneum is on the outermost part of the skin and can resist the invasion of strong acids and alkalis and even pathogenic microorganisms. It is equivalent to forming a physical barrier on the surface of the skin to prevent the evaporation of water in the body. In addition, there are some sebum secreted by sebaceous glands and sweat secreted by sweat on the surface of the skin, which emulsify to form a sebum film, making our skin surface balanced in water and oil, and looks moisturized. In addition, the stratum corneum also has the function of resisting ultraviolet rays. Therefore, we should not remove it frequently, but vigorously protect the stratum corneum.

How to increase the thickness of the stratum corneum

Method 1: Eat more foods high in collagen.

If we take some foods with high collagen content, our skin will become elastic and various skin problems will not easily come to us. And it can also effectively increase the stratum corneum appropriately, so that your stratum corneum will not be so thin. So which foods have a high collagen content? Foods such as fish, pork or milk are rich in collagen.

Method 2: Increase the frequency of physical exercise.

If you want to thicken the stratum corneum, you can also do some physical exercise. Physical exercise can effectively enhance our body's metabolism, and the metabolism of the skin will also increase to a certain extent. This can effectively promote blood circulation under the skin, enhance the skin's resistance, and also achieve the effect of thickening the stratum corneum of the skin, so start exercising from now on.

Method 3: Reduce the number of times you use facial cleanser.

Many friends know that some dust and grease on our face can only be washed off with facial cleansers, so they use strong cleansers to wash their faces every day. However, for friends with thin stratum corneum, this approach is not appropriate. Because the cleansing power of facial cleansers is too strong, it is easy to remove your already thin stratum corneum, causing the stratum corneum to become even thinner. Therefore, the editor here recommends that you reduce the number of times you use facial cleansers and only use warm water to wash your face.

What are the dangers of a thin stratum corneum?

Why is it not good if the stratum corneum is too thin? That is because if the stratum corneum is too thin, our skin will be more vulnerable to various external injuries, and it is easy to get allergic inflammation or be infected by some bacteria. Moreover, a too thin stratum corneum can easily cause red filaments to appear on the surface of our skin, commonly known as red blood streaks, and such skin will not look so beautiful. Moreover, if the stratum corneum of the skin is too thin, the adaptability to various skin care products is relatively weak. It is very likely that you cannot use skin care products and cosmetics that others can use casually, and you will cause allergies once you use them.
