Goji Spa by Nescens

This is the most technical spa in Val d'Isère, and unapologetically so: the menu is built on Nescens cosmeceuticals, formulated under Professor Jacques Proust, with an in-depth skin consultation before every anti-ageing protocol. Facials run from the Detox to the Soin Re Nescens, lifting and remodelling, in sixty minutes or ninety. The house also has an exclusive ritual, Le K2 Collections by Nescens, face and body. On facilities: glacier-water hydrotherapy, jacuzzi, hammam, sauna, fitness and a twelve-metre pool. And (a detail that counts when travelling with family) a treatment menu for children, the Petits Pandas Roux.
