How often may I use the Wartner Corn & Callus Removal Pen?

The Wartner Corn & Callus Pen should be applied once daily for 4 days. After this treatment of 4 days, the skin will peel off over the next 4 days. You can carefully remove the peeling skin under lukewarm water. After the treatment, new skin (free from corns or calluses) will form. You can repeat this treatment schedule up to 4 times.
