What should an esthetician do when a client presents with signs of infection?

When a client presents with signs of infection, the most appropriate and responsible action for an esthetician is to inform the client and suggest a medical consultation. This choice is correct because health and safety are paramount in esthetic practices, and an infection can pose risks not only to the affected client but also to others who might be in contact with the same treatment area or tools.

By suggesting a medical consultation, the esthetician ensures the client receives the appropriate medical attention required to address the infection properly. It demonstrates a commitment to the client's health and wellbeing. This choice respects the ethical obligations of estheticians to prioritize the safety of their clients.

In the context of the other options, performing the service cautiously would be irresponsible, as it could exacerbate the infection or lead to further complications. Ignoring the issue because the client insists undermines the esthetician's professional responsibility and could lead to serious health consequences. Continuing with the service as if there is no concern is disregarding the signs of infection altogether, which is not a safe practice in any health or beauty-related profession. Thus, the correct course of action is to inform the client and recommend they see a medical professional.
