I am glad you are asking this question; it shows that you are being cautious about who does your injections and this is the best way of getting a good result. An ENT with experience in botox or dysport should be able to perform the treatment for you. That said, there are many providers, including nurses and physicians, and even aestheticians, that are jumping into the aesthetic space. They take a weekend course and then start performing Botox. The four aesthetic core specialties are: Dermatology, Plastic Surgery, Facial plastics, and Oculoplastics. Providers in the core will typically have thousands more hours and procedures under their belts. It makes sense to go to a core physician for your treatment.
