There is no "certification" per se, like one might see in a "board certified plastic surgeon", etc. Juvederm can last upto a year, so choose someone with an aesthetic eye, and experience. I would insist that the doctor do it.
The safest way to insure you are getting a properly trained physician is to check them out with the American Board of Medical Specialties. You want an injector who is board certified in either dermatology, plastic surgery, oculoplastic surgery, facial plastic surgery. Some opthalmologist and otolarygologists are also very capable. Once you verify they are board certified in the right thing ( ie not dentistry, ER, OB Gyn, etc which are not core aesthetic specialties) ask to see their before and after photos. Just because you are board certified does not mean you have a good artistic touch with fillers.
