According to the 2013 International Journal of Cosmetic Science, 60% of women consider themselves to suffer from sensitive skin. To cater to this group, Sothys has developed a line containing thermal water from the town of Spa in Belgium. The gentle formulation is claimed to reduce skin sensitivity, helping block epidermal receptors responsible for the sensations of pain, irritation and itching on the skin's surface. The active water has a low mineral content, and a pH close to that of the skin.
Products in the line include Micellar Cleansing Water; Soothing Velvet Cream, for dry and sensitive skin; Soothing Melting Fluid, a light, fresh fluid suitable for sensitive, combination skin; Soothing SOS Serum; and Nutri-soothing Mask.
