Backed by 15 years of advanced research, the Lancôme laboratories present the Advanced Génifique serum, which draws its innovation from the science of the microbiome. What is the microbiome? It's an ecosystem of billions of beneficial micro-organisms that lives on the surface of your skin. A stronger, more balanced microbiome gives skin a healthy, beautiful appearance. Advanced Génifique radiance activating serum has been proven to reinforce the skin's microbiome. After just one bottle, the key signs of youthfulness appear visibly improved, and skin regains its suppleness and radiance, day after day.
