A valid and current medical license is required in Florida to practice medicine. Botox therapy would fall under this requirement.
It's best to get your BOTOX from a Facial Plastic Surgeon, Plastic Surgeon, or Dermatologist. In Florida, MD's, DO's, DMD's, PA's, and Nurse Practitioners can inject BOTOX. Nurses can't inject BOTOX in Florida. I believe that Podiatrists, and maybe even Pharmacists can also inject.
