Which action is not allowed for estheticians according to regulations?

The action that is not allowed for estheticians according to regulations is treating infectious skin diseases. Estheticians are trained to perform a variety of skincare treatments, such as facials, makeup application, and extractions of non-infected comedones. However, the treatment of infectious skin diseases falls outside the scope of practice for estheticians. This restriction is in place to ensure that clients receive appropriate care from qualified professionals, such as dermatologists or medical practitioners, who have the necessary training and expertise to diagnose and manage infectious conditions.

By adhering to this regulation, estheticians help protect the health and safety of their clients, as improper treatment of infectious skin diseases can lead to complications or worsening of the condition. This clear boundary helps maintain professionalism within the esthetics field and ensures clients get the best care for their specific skin concerns.
