- Medicine is an ever-evolving Science and what we learn here is that we are now changing our views on germs; towards the ever-increasing importance of seeing ourselves as being part of a Global Ecosystem.
- On the skin, there are around 100000 bacteria for every cm2 and the type of bacteria and density varies according to the local environment: from the dry breathable “desertlike” surface of the skin to the moist (and oily) “tropical” environment of sebaceous glands.
Germs on the Skin (Cutaneous Microbiome)
- With regards to skin, Atopic Dermatitis (AD) is associated with a deficient strain of bacteria (coagulase negative Staphylococcus) that leads to favorable conditions for “bad germs” to infect the area (Staphylococcus Aureus). (Further reading: https://telemedskin.com/why-healthy-bacteria-are-so-important-in-normal-skin/)
- Studies are also being done for other conditions such as Acne and Psoriasis.
Germs in the Gut (Gut Microbiome)
- Systemic Disorders – Imbalances in the Gut have been linked to a wide range of diseases…after all our Gut is also “our Second Brain”*.
- Skin Disorders – In young children inflammation on the skin occurs when the gut shows “a lower relative abundance of certain bacteria (for example, Bifidobacterium, Akkermansia and Faecalibacterium), a higher relative abundance of particular fungi (Candida and Rhodotorula) and a distinct fecal metabolome enriched for pro-inflammatory metabolites.“ (Further reading: https://telemedskin.com/childhood-eczema-and-germs-in-the-gut/)
Further solutions for the Skin
- A mutually beneficial partnership with healthy bacteria and the body is a way forward.
- Instead of destroying them with Antibiotics we could adopt a more constructive approach by creating favorable local (topical) conditions for them to develop or “seeding” the area.
- Also flora control of the digestive tract might be the way to reduce inflammation – which is not only a feature of Eczema (Dermatitis), Psoriasis and Acne, but also of Aging (Photoaging)
- These theories integrate us as being part of the Environment…and understanding this benefits us as individuals.
