mitochondrial free radicals vs control (senescent fibroblasts)
0% After 60 min., efficacy on
Excess of free radicals (ROS: Reactive Oxygen Species) contribute to oxidation of mitochondrial DNA & RNA, proteiens, lipids, sugars
RESULTS: Significant higher protection
with EPHEMERTM with ➘ cellular ROS(P<0.05)
-71% Significant mitochondrial protection -100%
with EPHEMERTM with ➘ mitochondrial ROS(0.06<P<0.1) No efficacy of sporophyte extract on mitochondrial ROS
■ 0.01% of EPHEMERTM ■ 0.01% of Sporophyte extract of Undaria pinnatifida

Conclusion In conclusion, while development of biotechnologies in cosmetic products is still at the early stages, they largely echo the major global challenges to preserve the environment and do not lack novelties for the future. On one hand, the study of the culture‘s medium impact can guide phytochemistry or improve the industrial yield for new eco- designed cosmetic ingredients. On the other
hand, all the research around biotechnologies and their ability to preserve biodiversity makes it possible to discover new species in places largely investigated.
