So far I do see results but this was only my first session. Yes it is painful but the person who is administering mine is using lidocaine to see if it helps with the pain and I felt that it did. She is experimenting with it on a few patients to see if this decreases the pain and swelling but turns out the same results.
I'm happy with my experience thus far. Honestly though it depends on you and what you are willing to do for beauty. Cosmetic surgery is just as painful if not more and you also swell and bruise and the healing time is much longer.
