PARIS — L’Oréal has been involved in studying the human microbiome — the collection of microbes inhabiting a person’s body — which controls and regulates health. It’s expected that related findings will result in cosmetic and dermatological applications.


The French beauty giant recently presented some research results to journalists, including many from the scientific realm, in its Worldwide Advanced Research Center in the Paris suburb of Aulnay-sous-Bois.

L’Oréal’s research and innovation department has worked with numerous scientific teams, including Paris’ Institut Pasteur and New York University, to describe the microbiome of healthy and greasy skin, for instance. The balance and role of endogenous skin microflora is key in all this.

“Microbiome…is an essential partner for your skin,” confirmed Sophie Seite, scientific director at the dermatology laboratory at La Roche-Posay — one of L’Oréal’s brands.

A focus for L’Oréal Advanced Research, La Roche-Posay laboratories and a couple of professors has been the microbiome of skin with atopic dermatitis. Among their findings is that the skin microbiome of people with atopic eczema rebalances — alleviating the condition — after treatment with an emollient containing 100 percent La Roche-Posay spring water.

“Treatment with Lipikar Baume AP modifies the microbiotic diversity associated with atopic lesions,” said Seite, referring to one of the brand’s products.

Looking ahead, the microbiome could also serve as a target for the treatment of diseases, for instance, according to Thomas Luger, professor of dermatology at the University of Münster.
