To effectively smooth a callus using an electric file during a pedicure, what should practitioners ensure?

When using an electric file to smooth a callus during a pedicure, it is essential for practitioners to ensure that the feet are dry. A dry surface allows the electric file to effectively remove rough skin and calluses without slipping or dragging. Moisture can hinder the effectiveness of the tool, making it difficult to achieve a smooth finish.

Smoothing a callus requires precise control of the electric file, and having a dry foot provides better grip and traction for the tool. Additionally, using an electric file on wet or moist skin can lead to safety issues, as the tool may not perform properly and could increase the risk of injury.

While soaking the feet, applying lotion, or ensuring warmth may be beneficial for overall foot care and comfort, they are not conducive to the effective and safe use of an electric file for callus removal. Keeping the feet dry is fundamental to achieving the desired results during this part of the pedicure process.
