Three Balances Of Skin
Sunmay International | Updated: Feb 20, 2019

Three balances of skin

Balance of Skin Metabolism

The top layer of the skin is the epidermis, and the epidermis is divided into 4 to 5 layers. The most important is the outermost stratum corneum and the innermost base layer. The stratum corneum is the most important protective barrier for the skin. Without it, the skin cannot retain moisture, it cannot isolate microorganisms and harmful substances, and it cannot resist ultraviolet rays. The basal cells gradually grow from the inside to the outside with a period of 14 to 28 days, penetrate several layers in the middle, and finally evolve into the stratum corneum.

Water and oil balance

Sweat glands and sebaceous glands secrete water and oil to moisturize the skin, and of course natural moisturizing factor (NMF) to maintain the water content of the stratum corneum. Normally, skin needs not only water , but also lipids and other water-retaining ingredients.

There are also precise structures and a certain proportion of lipids distributed between the keratinocytes, which play an important role in maintaining the intact and healthy skin barrier and preventing the excessive loss of water.

Invasion and resistance balance

The skin is exposed to many harmful factors every day, such as ultraviolet rays, harmful microorganisms, various harmful chemical and physical factors, and so on. However, the structure of the skin has a certain defense force, and it can repair the damage by itself.

Finally, we need to protect the integrity and health of our skin, improve the skin's resistance, and try to avoid external damage. Keep skin in its best condition.
