A haven of natural beauty in a former art gallery
It all began on the Île de Ré, with a passion for the sea, nature, and skincare. Nestled on the charming Place de l'Église, in the heart of the historic village of Saint-Martin-de-Ré, the Biosalines boutique is much more than just a shop: it's a true sensory escape. Housed in a former art gallery, it elegantly combines heritage architecture, clean design, and a marine theme.
A discreet address with timeless charm
Behind a simple facade, facing the church, the boutique opens onto a light-filled interior, blending minimalist simplicity with a warm and welcoming atmosphere. Exposed stone, raw wood, and contemporary touches authentically evoke the brand's artisanal and island spirit. Biosalines is, above all, the story of a meeting: that of Virginie and Olivier, a passionate couple, and a salt worker from the Île de Ré. During a casual conversation, this craftsman, with his ancestral skills, offered them the opportunity to take over his cosmetics brand, thus giving birth to an adventure steeped in tradition and nature.

An immersive experience guided by the expert advice of Cathy and Suzy
From the moment they step inside, visitors are greeted by fresh, marine scents that awaken the senses. Cathy and Suzy provide a warm and personalized welcome. They take the time to offer advice, introduce the different textures, and passionately explain the benefits of the natural active ingredients in each product.
Exceptional skincare with marine active ingredients
The Biosalines range stands out thanks to its demanding formulation: between 95 and 99% naturally derived ingredients, without compromising on effectiveness or sensory pleasure. Sea fennel, samphire, wakame seaweed, golden seaweed… Each selected marine plant is rich in minerals, antioxidants, or amino acids, to offer the skin radiance, protection, and vitality.
