What is the first step that should be taken in every treatment?

Sanitizing hands is crucial as the first step in every treatment because it ensures the hygienic safety of both the client and the esthetician. Proper hand sanitation helps to prevent the transfer of bacteria, viruses, and other pathogens that could lead to infections or complications during the treatment process. By adhering to this practice, estheticians not only protect their clients but also maintain a professional standard in their services.

While cleaning the treatment area, consulting with the client, and setting up the equipment are important steps in the process, they follow after ensuring that the esthetician's hands are clean. This foundational step sets the tone for a safe and effective treatment, highlighting the significance of hygiene in the esthetic field.
