I'm curious about reviews of shoulder fillers to improve upper body proportions.

I have recently become very interested in shoulder fillers and am looking for information. I intend to improve my existing shoulder line, and I am curious to know what changes have occurred after the procedure. In particular, I would appreciate it if you could tell me about the duration of the results and your satisfaction levels, as well as any precautions I should take when choosing a clinic or any places you would recommend. I would like to hear various opinions before getting the procedure.
