What is the only legal method for a licensee to remove calluses?

The only legal method for a licensee to remove calluses is through the use of a liquid callus remover product. These products are specifically designed to chemically dissolve thickened skin and calluses, promoting safe and effective removal while minimizing the risk of injury. Liquid callus removers typically contain active ingredients that break down the protein structure of the callus, allowing for easier removal without the need for sharp instruments.

Utilizing a fresh razor blade is not appropriate as it poses a significant risk of cutting the skin, which can lead to infections or complications. Similarly, while a metal file may be used for smoothing the surface of the skin, it is not considered a legal method for callus removal due to the potential of causing damage or irritation. Soaking in hot water can help soften calluses but does not constitute a legitimate or effective method for their removal. Therefore, the use of a liquid callus remover stands as the only approved and safe practice for this purpose.
