An actor to revive the secretion of sebum
We are conducting active Research on the skin microbiome, an ecosystem of 100,000 billion microorganisms living on the surface of our skin. These bacteria play an essential role in our body, continually interacting with our cells. But this protective screen is fragile, and its balance can be easily altered by the excessive multiplication of protective bacteria or the installation of unwanted bacteria. If there is an imbalance, then skin damage may appear - micro-inflammations, eczema, or acne.
In this Congress, we presented the latest results, which show that it is possible to restart sebum production thanks to the supply of specific nutrients. Sebum plays an important role in the skin's balance by forming a protective film on its surface. It participates in particular in maintaining hydration. Relaunching the secretion of sebum, for example, at menopause, could be a key avenue in the fight against aging in women after 50 years.
An ally in the fight against pollution
Another study conducted on the subject also allowed us to highlight a direct link between air pollution and the microbiome modification.
In previous work, our researchers had shown that the combination of polluting particles and solar radiation such as UVA had harmful effects on our skin's quality.
In heavily polluted cities, in particular, we can observe the skin's premature aging with the appearance of large pigment spots and the worsening of wrinkles.
On the occasion of this Congress, we showed that polluting particles were associated with a change in our skin microbiome. Therefore, targeting the microbiome could be a new approach in the fight to reduce the effects of the environment on the aging of our skin.
