The microbiome is the complete set of millions of living micro-organisms present on the surface of our skin. A genuine extension of ourselves, it fulfils a role as a protective barrier. Changes in these flora under the influence of different factors (UV, cold, stress, hormones, etc.) make the skin hyper-sensitive: the skin overreacts to these types of aggression and can no longer defend itself. Drawing on these latest discoveries in skin biology, the Crème No 2 Nuage strengthens and restores balance to the skin flora. As well as this action, they moisturise and act as genuine anti-skin stress care by calming sensations of discomfort and reducing irritation and redness.
