Maintaining the integrity of a sterile field is critical in any medical or aesthetic treatment to minimize the risk of infection and ensure patient safety. Washing hands thoroughly before treatment is an essential practice because it significantly reduces the number of pathogens on the hands, which can easily contaminate the sterile field. Proper hand hygiene is the first line of defense against infection, as it prevents the transfer of harmful microorganisms from the technician to the treatment area and the patient.

While using gloves is a common practice in maintaining sterility, gloves can still become contaminated if hands are not clean beforehand. Cleansing the work surface is also important, but it alone is not sufficient to ensure that the technician's hands—potential sources of contamination—remain clean. Limiting client movement can contribute to maintaining a sterile environment, but it does not address the primary need for thorough hand sanitation prior to any medical intervention. Thus, thorough handwashing is a fundamental and essential practice for ensuring the integrity of the sterile field during treatment.
