Exfoliating foot treatment mask. This easy-to-use, ultra-exfoliating foot-sock treatment transforms feet after a single application, over the course of several days. Dry, rough, damaged, callused skin on the feet peels gradually away to reveal soft, smooth, baby-soft skin beneath. Xerial products' concentration of urea varies between 5% and 50% providing different types of skincare action accordingly. Deep cracks and areas of hard skin are eliminated. No parabens, no fragrance. How to use: Wear svr xerial peel 2x20ml for 1 hour, then rinse. 4 to 5 days later, dead skin will naturally and gradually begin to fall away. In less than 2 weeks*, the feet are visibly transformed. Plan for the treatment to happen at the start of a week-10 days period in which you can wear closed shoes / socks to contain exfoliating skin. Skin will be better than ever before within a fortnight. Warnings & cautions: Don’t use if you are allergic to any of its contents. For external use only
