Dry and squamous skin with psoriatic tendency, dry feet and calluses. All these skin problems are linked to hyperkeratization: your skin goes too fast and makes too many cells. The layers of skins accumulate and form plates, plugs (Pilar Keratoses) and Horn. Xerial smoothes and limits the proliferation of keratocytes thanks to formulas very concentrated in urea, from 5% to 50% depending on the skin problem. Suitable for sensitive skins.
