The skin's microbiome - the living protective shield of your skin

Your skin protects your body from external influences. But the skin itself also needs protection – among other things, the so-called microbiome is responsible for this. The skin microbiome behaves like a complex biological system. As long as the system is in balance, it can protect your skin from external influences. That is why the microbiome is so important for skin health and natural beauty.

What exactly is the skin microbiome?

On the surface of the human skin is the skin microbiome, an ecosystem of almost invisible microorganisms. The skin microbiome is therefore the totality of all these living organisms that reside on the skin. These microorganisms – also called microbes – include bacteria, fungi and also viruses. The skin enters into a symbiosis with the microorganisms, which means living together for mutual benefit.

What are the functions of the skin microbiome?

The skin microbiome is important for your health. It has an important protective function against environmental influences, pathogens and UV light and is thus the living protective shield of your skin! The microbiome also interacts closely with the skin’s immune system and contributes to its normal function.

To ensure an intact protective function, the beneficial microorganisms keep the bad bacteria in check. However, not only the “good” microorganisms are essential. It depends on the right balance of the different microorganisms. Some bacteria and fungi can stimulate the immune system to protective reactions and ward off dangerous germs. At the same time, care should be taken to ensure that the beneficial co-inhabitants do not get out of hand either, as this can otherwise lead to skin problems. In some skin diseases, for example atopic dermatitis or seborrheic dermatitis, the altered microbiome contributes to the disease.

How can I support the skin's microbiome?

Fortunately, the skin microbiome is relatively resilient: after cleansing and disinfecting the skin, the microbiome changes only temporarily. However, in order to regenerate quickly, the skin’s microbiome needs an intact protective acid mantle (=hydrolipidic film) on your skin surface. The protective acid mantle consists of water, fat-splitting enzymes, dead cells, sebum and sweat, among other things, and has a slightly acidic average pH value of 5.5. It regulates the water balance of the skin, prevents too much moisture from escaping and also protects against external influences. An intact acid mantle is the basis of life for the skin microbiome.
