A Miami man was arrested on Wednesday, December 3, 2025, and accused by authorities of practicing medicine without a license and injecting ReNTox, a South Korean toxin product that is not approved for use in the U.S.

Yumyut Mustafa, also known as Yumit Mustafa, was taken to Miami-Dade jail. His bond was set at $5,000 on charges of practicing professional healthcare without a license, possession of prescription drugs with intent to sell and misrepresenting that he had a license to practice medicine.

Mustafa was arrested at his Y.M. Aesthetics, which operates out of Suite 1209 at the Latitude One office tower, 175 SW Seventh St. in downtown Miami. Security at Latitude One told a Miami Herald reporter that building management ordered the reporter not be allowed up to Y.M. Aesthetics’ office. The phone number for Y.M. Aesthetics’ Miami and New York locations wasn’t accepting calls Thursday.

State records say Mustafa registered Y.M. as a corporation on Sept. 19, 2024, and remains the company’s manager and agent.

In Florida, professional physicians and advanced practice registered nurses can inject Botox, as can registered nurses operating under a physician’s supervision.

Mustafa has never held a medical professional license in Florida, according to the state Department of Health’s online license search tool, which has information on a medical professional’s license status and discipline history.

According to the arrest report, a tip from an anonymous source via the Department of Health pointed the Miami-Dade Sheriff’s Office toward Y.M. Aesthetics and Mustafa practicing without a license.

AmSpa’s take: Obviously, medical aesthetics should only be practiced by people who are properly trained and credentialed to perform specific procedures according to the laws of the state in which the practice is located.
