Anne Sémonin
With a bespoke treatment range designed by Anne Sémonin, the Spa at 51 is centred around an ‘a la carte’ concept, tailored to guests’ requirements. Each treatment begins with a full consultation, where an Anne Sémonin trained therapist consults the guest on his or her specific skin needs. The treatments are then adapted and ‘made-to-measure’ in the famous Anne Sémonin tradition.
The first brand to combine trace elements and essential oils within a complete spa range, all Anne Sémonin treatments present a highly individualised and holistic approach to beauty. Anne Sémonin products use only natural ingredients, and are formulated using state-of-the-art skincare science; blending traditional remedies and ingredients with new technology and formulations.
Highlights from the Anne Sémonin treatment collection include:
- L`Expérience Anne Sémonin Signature Facial – The ultimate bespoke facial designed for The Spa at 51 incorporating a client-specific intensive eye treatment, and a back and neck massage.
- Anne Sémonin Serenity Treatment with Hot Stones – An all-embracing treatment incorporating a full Phyto-aromatic facial followed by a hot stone massage.
