I just got it at a local dermatologist. I tried it on my chin and thought it had a lot of jaw muscles, so I got it, but it didn't seem to have much effect . If it does, keep getting it, or if it's not enough, I think I'll have to have surgery. I didn't see any effect, but it's a good treatment that can take a bite without any burden and is a jackpot if it hits the jackpot
