Moisturising and soothing.
Hypotonic water has a low concentration of ions, which helps it penetrate the skin through the mechanism known as osmosis.
This type of water can be found at the Caldes de Boí Spa, specifically in the “Font del Bou”, “Font del Boix” and “Font de la Tartera” springs. And, of course, it is included in all Boí Thermal products.
Hypotonic water revitalises and remineralises the skin. In addition, it encourages cellular nourishment and prevents wear.
The penetration of hypotonic water into skin cells causes them to increase in volume and turgor. The result is visibly softer and more flexible skin that is moisturised and soothed; it also provides a wonderful feeling of comfort.
In the entire Boí Thermal product line, high-quality natural ingredients with proven efficacy are paired with hypotonic water. The water not only serves as a vehicle, but is actually an active ingredient that is just as important as the other components.
