After a soft opening of the hotel in February, La Reserve Paris Hotel & Spa has opened its three-treatment-room Nescens Spa.

The spa exclusively uses Swiss brand Nescens’ cosmeceutical products and anti-ageing treatments. Specialised programmes begin with an in-depth analysis of the skin by a Nescens-trained expert, who then creates a personalised preventative and corrective programme.

A Signature Nescens Better Ageing Body massage uses drainage techniques and targets muscles and energy meridians as part of a long-term preventative approach. Combined with the use of a lymph drainage device, the massage is designed to release blockages and ease tension while activating cell regeneration and stimulating skin oxygenation and muscle tone. The 80-minute treatment costs €260 ($288, £186).

The spa includes a dedicated male treatment room with special Nescens treatments for men available. The spa at La Reserve Paris is also home to a 16m (52ft) swimming pool, fitness centre with personal trainers available, and a steamroom.

The hotel, which includes 26 suites and 14 bedrooms, is housed within a Haussman-style mansion in a highly private location. Designer Jacques Garcia drew inspiration from James Tissot canvases and his depictions of bourgeois Paris in the early 19th century to create a home that evokes the era.

The accommodation includes intricate woodwork, mouldings and cornices modelled on historic styles that were discovered during the restoration of the building. The rooms and suites are decorated in four distinct colour palettes – bronze, beige, prune and tea-rose – and the walls hang with silk, damask and brocade, as well as taffetas and velvets.

Owned by Michel Reybier, La Reserve also operates La Reserve Ramatuelle and La Reserve Geneva, both of which feature spas.
