Skin problems
The influence of the microbiota
on our skin

Our skin is exposed to multiple aggressions which it must face to maintain its integrity and renew itself. These aggressions generate inflammatory and oxidative stress that negatively impact its youth and radiance.

The intestinal microbiota, by exercising a natural barrier function, prevents the passage of foreign elements through the intestinal mucosa and thus avoids the spread of these inflammatory and oxidising mechanisms in the body. By promoting the integrity of the intestinal mucosa, the microbiota actually strengthens the cohesion of all our tissues. 

It is also the guarantor of the digestive work which consists of extracting minerals (zinc, silicon, selenium...), vitamins (A, E, B...), trace elements and fatty acids from food, necessary for the proper functioning of all the organs and particularly the skin. The intestinal microbiota, as an actor in this metabolic work, thus favours the bioavailability of micronutrients that are essential for the skin's regeneration and beauty mechanisms.

Gut/Skin link
Beautiful skin starts with the gut

The skin is the largest organ in the body and in most cases reflects our "inner" health, and therefore the health of our gut. 

 

The gut-skin link is proven: some innate immunity receptors are identical even if the nature of the bacteria is different. 

 

Just like our intestine, the skin is an ecosystem, composed of billions of micro-organisms (bacteria), called microbiota. 

 

The microbiota evolves according to our environment, our lifestyle and our age. If it is unbalanced, the microbiota can no longer play its role as a shield against external aggression and limit the impact of oxidative stress on our cells. The proliferation of bad bacteria accelerates the ageing of the skin and favours the appearance of acne, rosacea, eczema, redness... and other irritations.

The evolution of the microbiota
Three main phases

According to recent publications, the microbiota evolves mainly at each major hormonal change in life. The skin experiences three key moments

THE BIRTH

With a different microbiome depending on whether the birth is vaginal or caesarean. Sterile in the placenta, the colonisation of the skin by micro-organisms begins at the moment of passage to the external environment. Vaginal delivery transmits vaginal and even intestinal bacteria such as Lactobacillus to the baby. Caesarean delivery transmits skin bacteria such as Staphylococcus. Children born by caesarean section have a higher risk of eczema.

PUBERTY

Increased sebaceous secretions and sweat alter the skin's microbiome

MENOPAUSE & ANDROPAUSE 

See a drop in sebum secretion and a diversification of the microbiota.

Throughout adult life, the microbiota will remain relatively stable if there are no lifestyle changes.
