Which action is NOT recommended for an esthetician when handling tools?

Using visibly contaminated tools is not recommended for an esthetician because it poses significant health risks both to clients and practitioners. Ensuring that tools are clean and sanitized after each use is crucial in preventing the spread of infections and maintaining a safe environment for services. The practice of storing tools in a clean environment further supports hygiene by reducing the exposure of tools to contaminants. Regularly inspecting tools for damage is essential to ensure they remain functional and safe to use. Each of these actions contributes to adherence to health and safety regulations designed to protect both clients and practitioners in an esthetics setting.
