What should a professional do when performing a treatment on a new client?

Obtaining a thorough medical history is essential when performing a treatment on a new client because it helps identify any medical conditions, allergies, or sensitivities that could affect the treatment plan and the client's safety. Understanding a client's health status ensures that the esthetician can customize the treatment to meet individual needs and mitigate any potential risks. This critical step not only demonstrates professionalism but also fosters trust between the client and the practitioner, ensuring a safe and effective treatment experience. It is a fundamental practice to conduct a proper consultation to gather relevant information before proceeding with any treatments.
