Cutaneous microbiota

Stress, hormonal changes, exposure to the sun and to pollution, excessive use of antibacterial products, as well as diet, are all factors liable to disrupt the skin microbiota.

Yes, the micro-organisms present on our skin are not the same everywhere. The face, armpits, feet and intimate areas, for example, have different microbiota.

An imbalance of the skin microbiota, particularly a decrease in protective bacteria such as Staphylococcus epidermidis, may be associated with the onset or worsening of eczema.

At present, although few studies have explored the possibility of rebalancing the skin microbiota, promising data suggest that incorporating prebiotics and probiotics into skincare routines could play a beneficial role.

An imbalanced skin microbiota may manifest as irritation, redness, spots, excessive dryness or sensations of tightness, often accompanied by increased skin sensitivity.

Yes, studies show that the skin microbiota of men and women differ, particularly due to hormones. Men often have a more diverse microbiota and a greater quantity of bacteria.

Yes, the skin microbiota varies with age. In young individuals, the microbiota is generally more balanced and diverse. With age, microbial diversity tends to decrease. A major restructuring is particularly observed at puberty, under the effect of hormonal variations that modify sebum secretion.

The skin microbiota contributes to the defence of the skin by limiting colonisation by pathogenic micro-organisms. It also helps regulate cutaneous immunity.

It develops from birth and evolves according to the environment, age, and lifestyle habits. Its composition varies depending on the areas of the body.
