Biologique Recherche Rive Gauche

This cult beauty brand has two “embassies” in Paris, one on each bank of the Seine. The company was founded by a biologist, a doctor and a physiotherapist, so it approaches beauty as much more than skin-deep. Travelers can book a beauty assessment followed by a custom facial, and the aesthetician will analyze their skin for hydration, absorption quality, firmness and more. She will then customize a treatment. I left with a visible glow and, more importantly, tips like why my skin needs a foaming cleanser instead of an exfoliant and why I should slather rich eye cream on when flying. Because many Parisian women include visits here in their regular beauty maintenance, we recommend booking a few weeks in advance.
