Where can current licenses be displayed by the licensee?

The correct choice highlights that current licenses must be displayed in a manner that allows clients and inspectors to easily view them. Displaying licenses at the licensee's workstation or in a public notebook fulfills the requirement for visibility, thereby promoting transparency and compliance with regulatory standards. This practice not only assures clients of the legitimacy and qualifications of the service provider but also aligns with the regulations that govern the esthetics profession, enhancing accountability.

The other options do not meet these criteria. For example, displaying a license only in a private office restricts visibility and does not allow clients or inspectors to verify the license upon entering the establishment. Posting the license solely on social media fails to provide a physical, on-site verification method, which is typically necessary for inspections and immediate client assurance. Lastly, keeping a license in a locked cabinet completely obfuscates it from view, contrary to the intent of having the license accessible and visible to the public as a means of assurance and compliance.
