Do we need to know any special technique for Callus Peel treatment? Is it hard to do peel off and buff calluses on your heel?

No, there are only 4 easy steps as following. Patch & Wrap (stay for 15 Min) Peel, File and Moisturize. If you once tried, you can do it at once. Softly and gently peel off and buff calluses, you can do it without any forces.
