For decades, the focus in skin research has been on the physical barrier. New research now unveils a diverse community of micro-organisms that live on the skin barrier - THE MICROBIOME. Both the physical barrier and the microbiome have their own functions and how they interact with each other is just being discovered. This new research has demonstrated that for healthy skin, it is not enough to maintain the natural protective barrier alone. In fact it is also important to consider the microbiome, skin’s “invisible barrier.” A pioneer in advancing dermatology, La Roche-Posay has dedicated 6 years of research and conducted more than 10 clinical studies to gain a new understanding on the microbiome, its inter-correlation with the physical barrier and what it could mean for the future of skincare. {Product provided for review/feature consideration}
