can a general practitioner inject filler in usa or it is done only by specialist?

In the United States, general practitioners can inject dermal fillers if they have received the necessary training and certification to perform these cosmetic procedures. While specialists such as dermatologists and plastic surgeons often have more extensive training in facial anatomy and aesthetics, many general practitioners have successfully incorporated these services into their practices after completing appropriate training. It's essential for patients to check the credentials and experience of any practitioner performing filler injections to ensure safety and optimal results.
