I started receiving the injections on May 30th and received 6 injections for deep cheeks and 3 injections for double chin at 2-3 week intervals until August 21st! Is the pain stinging? I don't need anesthesia, but it's bearable, but during the last session, it was a bit painful. The shape of my face has definitely become smoother, but there hasn't been a dramatic change. I'd be willing to get it if the price was cheaper,,, but the price is too expensive. I think I'll give it a try and get another procedure. Still, it was my first contouring injection, and so far there have been no side effects and my facial lines seem to have been organized, so I'm satisfied, although I'm not very satisfied.
