Just as our skin, plants host a wide variety of microorganisms. In particular, this microbiota colonises floral nectar and modifies its composition, affecting the behaviour of pollinators and thereby the fertility of plants.
Expectations of skin care consumers are constantly evolving. Current trends go towards both proven visible quick anti-ageing performance and protective effect while giving an increasingly preponderant place to greater naturalness.
If data are available to discriminate people appearing younger than their age, no in vitro study focuses on the cellular evidence explaining these observations. We investigated, from molecular to functional level, primary human skin cells isolated from aged healthy volunteers to highlight if distinct in vitro cellular behaviors could be observed.
