What’s the nicest thing your partner has ever done for you? We’re going to stick our neck on the line and say it probably didn’t involve the lengths that Charles-Edouard Barthes went to for his wife, Eriko Nakamura. Barthes is as French as you can get: born in St-Paul-de-Vence, he is impeccably attired, with a self-professed knack for “stylishness and seduction”. Falling “madly in love” with Nakamura, he created a whole skincare line to suit her sensitive skin, uniting the best scientific expertise from Japan with a distinctively French sensibility. Luckily for us, he decided to expand availability of the line outside his immediate family, with a range of products and four new treatments available at Rosewood London’s Sense Spa. As an exclusive UK home, the Sense Spa is a good choice, being nothing short of heavenly with its bamboo walls, wooden walkways over water and centrifugal design. Our recommendation? The Essential Fresh and Tone Ritual.
