MyMicrobiome Standard 18.10 tests products for our skin of face and body

For a Microbiome-friendly world!

If you look at the human body, each of us is like a planet in its own, which is home to trillions of "inhabitants". If you were to look at the human body through a microscope, you would discover deserts, river valleys, dangerous swamps, acid lakes and humid jungles. The ecosystems on this planet, our bodies, are overwhelmingly diverse - as are their inhabitants. Among these inhabitants, microbes are the undefeated masters in their ability to adapt to a wide variety of habitats.


For a healthy skin!

The skin is the largest organ of the body, averaging 1.8 m2 in size.

If you include all the wrinkles, sweat glands and hair follicles in the skin, the skin has a surface area of about 25m2!

Healthy skin microbiome
The skin provides space for millions of bacteria, fungi and viruses, our microbiome.

The skin is the first contact point between our environment and our body and acts as a physical barrier against pathogenic germs and toxic substances. At the same time, the skin provides space for millions of bacteria, fungi and viruses, our microbiome. A weakened skin barrier or a disturbed balance between commensal and pathogenic germs can lead to skin diseases or even systemic diseases in the whole body.

Physiological properties determine different ecosystems on our body. The various ecosystems of our skin are determined by UV light, pH, temperature, moisture, sebum content and surface texture. Thus, the skin is divided into oily, dry and moist areas. Depending on the different ecosystems, different microbial populations thrive in them. Cutibacterium acnes (formerly Propionibacterium acnes) and Staphylococcus epidermidis prefer to settle on oily areas (e.g. face, chest and back), whereas Corynebacteria and Streptococci are frequently found on dry areas (such as the outer side of the hand, forearm, calves) besides Cutibacterium acnes. Moist skin areas (such as the navel, the armpit or the buttock fold) are mainly inhabited by Corynebacteria and Staphylococci. In addition to bacteria, about 20% of viruses and a slightly smaller proportion of fungi, dominated by Malassezia species, live on our skin.

Skin microbiome
From © Byrd et al., 2018: The skin surface as well as the deeper skin layers and here especially the sweat glands and hair follicles are colonized by our microbiome.

The skin microbiome fulfils essential tasks for both our skin and general health. The microbiome works hand in hand with our immune system, trains it, stimulates it and supports it in fighting pathogenic invaders with the most diverse mechanisms. In addition, the healthy microbiome occupies space that pathogenic germs can no longer take up.

Over the last centuries we have done everything to eradicate the little companions on our bodies: the bacteria, fungi and viruses (all microbes) that keep us and our skin healthy. A disturbed microbiome (also called dysbiosis) has all kinds of consequences for our skin health: acne, atopic dermatitis, psoriasis, sensitive skin are just a few examples. You can find more details here: Skin diseases.

Unfortunately, the majority of conventional cosmetic and personal care products in local drugstores and supermarkets are still full of antimicrobial agents that interfere with our skin microbiome. The cosmetics industry is already doing a lot to change this, but we are still far from meeting the standard. Even if a product promises to be particularly microbiome-friendly or gentle, the consumer is still dependent on trusting the manufacturer because the control authorities behind it are lacking. Unfortunately, we have found that only behind very few of the promises there is scientific evidence.

Therefore, pay attention to our seal - only products that carry this seal are guaranteed microbiome-friendly and have undergone our merciless test. We are very proud to support manufacturers who seriously want to market gentle products on the one hand, and to provide consumers with guidance in this confusing market on the other.

Standard 18.10 examines cosmetic and personal care products for face and body. Depending on the application a distinction is made between dry, oily or moist skin areas.
