What must a licensee always wear when servicing a client?

When servicing a client, a licensee is required to wear clean outer garments. This ensures a professional appearance and maintains hygiene standards, which are critical in the esthetics field. Using clean garments helps prevent contamination and the spread of bacteria, which is particularly important in an environment where close contact with clients occurs. The expectation for a clean presentation not only reflects professionalism but also reassures clients about their safety and well-being during treatments.

While aprons and gloves, comfortable shoes, and protective eyewear are also important in certain scenarios, they do not universally apply to every type of client service. Clean outer garments, however, are a fundamental requirement regardless of the specific treatment being performed. This requirement aligns with health and safety standards that govern the practice, emphasizing the importance of maintaining cleanliness throughout the service.
