Spa Alaena facing the sea
Immersion at the Alaena Spa of the High Seas on the Isle of Yeu, an intimate 300 m² space dedicated to relaxation, just a stone's throw from the ocean. Nestled in the heart of a preserved natural setting, the spa invites you to a revitalizing break where the authenticity of the island and the energy of the Atlantic accompany every moment.
At the crossroads of dermatology and nature science, Alaena develops living cosmetology that combines the effectiveness of natural active ingredients with biotechnological innovation to reveal the vitality of the skin. Inspired by ancestral techniques like Kobido or Tui Na and enhanced by modern approaches such as LED or Alpha Hydroxy Acid peels, our face and body protocols offer a sensory and high-performance experience.
In this peaceful haven facing the ocean, each treatment becomes a suspended moment, designed to regenerate the skin, release tension, and reconnect body and mind.
