Thermal waters are used to provide skin comfort, particularly in the case of skin conditions.
36 women, trained in sensory analysis, applied 4 thermal waters with different mineral concentrations (Avène Thermal Spring Water 0.2 g / L, La Roche Posay, 0.4 g / L, Vichy 5 g / L , Uriage 11 g / L) on their cheeks. The four thermal waters provided a feeling of freshness after 5 minutes. After 10 minutes, the waters provided sensations of softness, suppleness and skin comfort, all the more important as the mineral concentration is low.
