Meta Analysis of Skin Microbiome: New Link between Skin Microbiota Diversity and Skin Health with Proposal to Use This as a Future Mechanism to Determine Whether Cosmetic Products Damage the Skin

Abstract

Abstract:There is a skin allergy epidemic in the western world, and the rate of deterioration has increased significantly in the past 5-10 years. It is probable that there are many environmental contributing factors, yet some studies have linked it primarily to the rise in the use of synthetic chemical ingredients in modern cosmetics. Our challenge, therefore, was to find a mechanism to determine the effect these substances have on skin health, and whether they really are a primary cause of long term damage to the skin. The first problem is the lack of any definitive way to measure skin health. Motivated by the overwhelming evidence for a link between deficient gut flora and ill health, we decided to look at whether our skin microbiota could similarly be used as an indicator of skin health. Our research illustrates how microbiota diversity alone can predict whether skin is healthy or not, after we revealed a complete lack of conclusive findings linking the presence or abundance of particular species of microbe to skin problems. This phenomenon is replicated throughout nature, where high biodiversity always leads to healthy ecosystems. 'Caveman' skin, untouched by modern civilisation, was far different to "western" skin and displayed unprecedented levels of bacterial diversity. The less exposed communities were to western practices, the higher the skin diversity, which is clear evidence of an environmental factor in the developed world damaging skin. For the first time we propose benchmark values of diversity against which we can measure skin to determine how healthy it is. This gives us the ability to be able to predict which people are more likely to be prone to skin ailments, and start to test whether cosmetic ingredients and products are a main cause of the skin allergy epidemic.Keywords: biodiversity; skin allergy; benchmark skin health values; effect of synthetic cosmetics on skin; 21st century skin ailments; measure skin health; healthy skin ecosystem; healthy skin bacteria; damaged skin bacteria; perfect skin

pH-Wert und mikrobielle Infektionen

“…Der saure pH-Wert, das Temperaturniveau, die anatomische Lokalisation und Feuchtigkeit sowie die verwendeten Hautreinigungsmittel und Kosmetika beeinflussen das Wachstum und die Aufrechterhaltung der residenten Flora; zugleich beeinflusst der Zustand dieser residenten oder Standortflora das Hinzukommen von transienten Mikroorganismen (Kontaktflora) [7,8,9]. Es ist unumstritten, dass der normale pH-Wert der Hautoberfläche günstig für die Hautmikroflora ist.…”

The microbiome of the skin

“…zabiegi higieniczne i kosmetyczne z wykorzystaniem substancji chemicznych. Powodują one nieustanne usuwanie ze skóry mikroflory, a zmiana warunków fizykochemicznych na powierzchni skóry utrudnia jej rekolonizację przez florę komensalną i jednocześnie stwarza warunki do jej kolonizacji przez patogeny [14,[34][35][36]. Proste wykluczenie podstawowych kosmetyków, takich jak szampon i dezodorant, powoduje w krótkim czasie (kilka dni) wzrost zróżnicowania mikrobiomu skóry [11].…”

Such agents constantly remove the skin microflora, and consequent changes in the physicochemical conditions on the surface of the skin make it more difficult for commensal microflora to recolonize the skin, at the same time creating favourable conditions for skin colonization by pathogens [14,[34][35][36]. A simple step of eliminating the use of basic cosmetics such as shampoo and deodorant increases the diversity of the skin microbiome during a short period (a few days) [11].…”

From stem cells protection to skin microbiota balance: Orobanche rapum extract, a new natural strategy

“…This layer represents the global innate population of microorganisms living on the skin's surface, and it interacts and works together with human skin cells to keep people healthy and protect them . A strong and balanced microbiota is essential for health and is achieved through protection of commensal bacteria and the prevention of pathogenic bacteria proliferation . A balanced skin microbiota offers skin an additional protection against premature aging …”
