For a better, Microbiome-friendly world!

MyMicrobiome Standard 20.10 - Infant skin microbiome

After birth, a baby's skin must adapt from what was previously a largely sterile and moist environment to a gaseous environment with various environmental influences. The hitherto completely microbe-free skin must now learn to cope with solar radiation, bacteria, fungi, but also mechanical influences such as friction from fabrics and contact with chemicals. The working assumption is that a "systematic" colonization of the child's body during the first months of life helps the skin to develop as a reliable barrier against inflammatory infections and other diseases.

Baby Microbiome

A baby’s skin is ever-changing, but the presence of five key microbes are essential for an intact microbiome:

Malassezia furfur

Lactobacillus crispatus

Malassezia furfur

Staphylococcus epidermidis

Malassezia furfur

Streptococcus mitis

Malassezia furfur

Corynebacterium tuberculostearicum

Malassezia furfur

Propionibacterium acnes

The test criteria for Standard 20.10 Infant skin

The product is subjected to four test runs as part of the "Microbiome-friendly" certification.

1. Quality test

This test is designed to guarantee the greatest possible microbiological purity of the baby care product. The product is first examined for possible contamination by mesophilic and aerobic microorganisms, i.e. bacteria, yeasts or molds (TAMC and TYMC). For baby skin products, the limit is 10² cfu/g or ml.

2. Balance test

It is essential that the baby care product does not disturb the balance between the most commonly-found skin microbe S. epidermidis and the harmful microbe S. aureus. A co-culture with both microbes is mixed with the product for a given period and then the ratio of the two microbes is compared with the untreated control group. This balance must not change in favor of S. aureus under the influence of the care product.

3. Diversity test

First, we cultivate the key microbes commonly found on baby skin. For the 20.10 Standard, these are C. tuberculosearicum, P. acnes, S. epidermidis, S. mitis, and L. crispatus.

A co-culture of all bacteria is mixed with the product to be tested and the change in diversity is compared with the untreated control group. The diversity of the baby skin microbiome must be preserved in terms of the most important key microbes.

4. Vitality test

A Microbiome-friendly product for baby skin should neither disrupt microbe diversity nor be detrimental to microbial growth. Using a model, the test simulates skin contact. Each key microbe is placed in direct contact with the product; In a second test, the microbe is covered with an agar layer and the care product to be tested is applied to it. This simulates the potential penetration of the product into deeper layers of the skin. Finally, the microbial growth of the two batches is compared to an untreated control group: the growth of microbes must not be significantly inhibited.

"The foundation for lifelong skin health and vitality is laid in the first months of life. Products tested according to the 20.10 Standard are gentle on sensitive baby skin and do not counteract the development of a healthy and stable baby skin microbiome."
