I went to a licenses esthetician. I ended up with duck lips. Would not do again. Lol. I think it was Juvaderm. My masseuse gets them though and hers look great!
I took a course in how to give lip fillers and botox, and from what I learned, a lot of places use jevaderm (they have a cool app that will show you your "results"). Make sure you go somewhere reputable with a properly trained nurse or doctor.
