Injection rules (or lack thereof in Nevada!) depend on the state you live in, and you can always consult the state's medical board for rules and regulations. However, in Florida, Botox can only be done by a Physician or a Nurse Practitioner / Physician's Assistant. A nurse (RN) is not allowed to inject Botox. However, you need to remember that Botox and fillers are a multibillion dollar business and there will always be less than legitimate providers or offices where they don't abide by the rules, hoping that they just don't get caught.... Please find an office where a board-certified physician is injecting. While it may cost a bit more out of your pocket, your results, care, and expertise should never be put into question to save a few dollars.
