Aesthetic medicine is both an exponentially growing specialty which has the potential to become an officially recognized, separate medical specialty. At the same time, there no regulation or standard minimum baseline of knowledge or training for people who offer injectables such as botulinum toxin or fillers. There is no competency assessment or "certification.." Many times, someone goes to a 4 hour course split between the two general topics and receives a certificate of course completion that is inaccurately referred to as a "certification." This is wrong. They may continue to improve from there or seek further training, but most do not. You don't know what you don't know and bad habits taught by bad instructors who are paid minimum for instructing from an outdated basic coursebook are continued despite bad outcomes or no difference after the treatment at all.
