Did you know that your gut is connected to your skin through a very special link? This is called the gut-skin axis. Today, our doctor Dr. Adrian Weingart explains what this is all about and why people with inflammatory skin diseases should be especially mindful of it.
We have already told you quite a bit about the gut-brain axis, but scientific findings show that there is another important connection originating from the gut. The skin is also strongly connected to the gut, which is why experts speak of a gut-skin axis. Although the gut and skin are relatively far apart, a connection can be made, for example, between common inflammatory skin diseases and an imbalanced gut flora.
Gut Microbiome and Skin Microbiome
When we at mybacs talk about the “microbiome,” we usually mean that of the human gut. There are over 1,000 (!) different and thus the most microbial species in our body. But there are actually many other microbiomes in and on us. One of these is the skin microbiome. After the gut, it has the second highest number and diversity of microorganisms. We know that the gut microbiome is essential for our immune system and digestion. But what is the purpose of the microbiome on our skin?
Simply put: Our skin microbiome is our shield! In short, human skin is the body’s first line of defense. It forms a physical and chemical barrier against the penetration of foreign substances or microorganisms and has an immune system that helps defend against infections. This happens, among other things, through the symbiosis of bacteria. The connection between our gut and skin microbiomes is so close that the skin can be called the "mirror of the gut"—it essentially shows how "healthy" we are inside.
What are the most common signs that the skin microbiome is out of balance?
There is no clear single sign here. Rather, a disturbed skin microbiome can influence many skin diseases, which then manifest differently. Our skin is inhabited by countless microorganisms that usually live in peaceful coexistence. The totality of bacteria, viruses, fungi, and mites is called the microbiome. In some skin diseases, this balance can be disturbed, leading to inflammation and eczema flare-ups. For example, in acne, there is an increased presence of so-called Cutibacterium acnes; in rosacea, more Demodex mites; and in atopic dermatitis, Staphylococcus aureus compared to healthy skin. Increasingly, studies indicate that people with acne and rosacea show a reduced diversity of their gut species. Thus, certain types dominate while others are missing, which can trigger inflammatory processes.
What can be done about it?
A targeted therapy can be initiated, for example, through topical treatment with prescription creams. Depending on the severity, a dermatologist should be consulted. In addition, daily lifestyle can be crucial. When it comes to skin care, “more is better” does not always apply. I often see that people with skin impurities use overly complex cleansing and care routines. Returning to three products can help the skin regenerate and regain balance:
- Mild cleansing morning and evening (no harsh scrubs to prevent micro-injuries to the skin),
- Skin care (fragrance-free care after washing the face),
- Sun protection (in the morning). The skin care should be individually tailored to the skin type. Consulting a dermatologist and/or medical cosmetician is also recommended.
According to the latest findings, the organs skin and gut seem to be more closely connected than previously thought. Our daily diet is considered an important factor influencing the gut microbiome. Clinical studies are currently investigating whether dietary modulation of the gut microbiome can have positive effects on the skin. What can already be said: a varied diet characterized by seasonal, unprocessed, plant-based staple foods appears to promote (skin) health. Probiotics and prebiotics are particularly interesting.
Is a holistic approach therefore important?
It is the combination of inside and outside that delivers the best results, taking into account sleep, nutrition, amount of exercise, and additional stresses.

By the way, the gut-skin connection also works positively in the opposite direction: studies have shown that a healthy gut flora ensures a healthier fatty acid profile of the skin, meaning more skin moisture and thus a stronger protective barrier. Further research shows how similar the gut and skin microbiomes are: they suggest that health strongly depends on the diversity of bacteria in both florae. The good news: you can directly influence the gut flora yourself with natural means. Probiotics combined with prebiotics have been proven to have a positive effect on the diversity of bacterial species in the gut microbiome.
The Dermabacs® - Probiotics for Acne & Skin Impurities, Rosacea, and Atopic Dermatitis
Our new synbiotic line Dermabacs® is based on the latest microbiome science. The included bacterial strains have been tested for effectiveness against acne, rosacea, and atopic dermatitis (neurodermatitis) in clinical studies (see below). Additionally, it contains 10 mg of zinc, which strengthens the immune system, reduces redness, inflammation, and irritation, and decreases sebum production. Zinc has been proven to help with acne, atopic dermatitis, other inflammatory skin diseases, and psoriasis.
In summary, it can be said that the gut and skin communicate through their microbiomes. If certain types of bacteria dominate or are completely missing, inflammatory processes can be triggered. The latest studies in microbiome research and nutritional science suggest that certain foods can positively influence the skin’s appearance. These include omega-3 fatty acids and probiotics.
