A medical doctor, registered nurse or physician's assistant can all perform Botox injections. In the states of New York, California, Florida, Texas and Oklahoma, licensed health professionals can inject Botox under the supervision of a medical doctor, as stated by Shape magazine.
Each state has different regulations on who can inject Botox. With the popularity of Botox growing as an easy fix for wrinkles and age lines, spa professionals can take a 1-day or weekend training course and begin injecting the toxin in a medi-spa or at-home Botox parties.
It's important that recipients use a registered or licensed provider of Botox who understands how to handle negative side effects. Poorly performed procedures can leave the face paralyzed and puffy with no movement or expression, as reported by the New York Daily News.
