The cutaneous microbiota, composed of beneficial protective bacteria, can become unbalanced due to external factors such as the excessive use of harsh cosmetic products, stress, or hormonal changes. When this balance is disrupted, the microorganisms present on the skin can proliferate excessively, leading to skin problems such as acne, eczema, or irritations.
The skin microbiota can be disrupted by factors such as the excessive use of antibacterial products, hormonal changes, stress, an unbalanced diet, and environmental aggressions like pollution.
Does the skin microbiota vary across different areas of the body?
The cutaneous microbiota varies across different areas of the body, influenced by factors such as the level of humidity, sebum production, and exposure to external elements.
Is there a link between skin microbiota and eczema?
An imbalance of the skin microbiota, particularly a reduction in protective bacteria such as Staphylococcus epidermidis, is often associated with the onset or worsening of eczema.
How to rebalance a disrupted skin microbiota?
Currently, although few studies have explored the possibility of rebalancing the skin microbiota, promising data suggests that incorporating prebiotics and probiotics into the skincare routine could play a beneficial role.
How can I tell if my skin microbiome is unbalanced?
An imbalanced skin microbiome can manifest itself through symptoms such as irritations, redness, spots, excessive dryness or feelings of tightness, often accompanied by more sensitive skin.
Does the skin microbiome vary according to sex?
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 larger quantity of bacteria.
Does the skin microbiome differ with age?
Yes, the skin microbiota does vary with age. In younger individuals, the microbiota is generally more balanced and diverse. As we age, microbial diversity tends to decrease. A significant restructuring is particularly observed during puberty, due to hormonal fluctuations that alter sebum secretion.
