11 Best Spas in Paris, From Dior to La Mer | Condé Nast Traveler

"A curvy jewel‑box whose name nods to “circle,” this Japanese beauty salon treats more than skin, weaving lifestyle and nutrition into each personalized ritual. Over 90 products—featuring all‑natural essences from organically grown plants—power holistic treatments that engage all five senses. Signature journeys include a body massage and custom facial with Kobido; you can add a lymphatic leg massage, or explore textures like Sea Mud from Okinawa and Hot Spring Lotion from the Tateyama Mountains, then close with matcha or green tea from Yakushima Island." - Kasia Dietz
