They recommended 100 units instead of 50 units because I have a lot of jaw muscles. Since it was my first time, I was worried it might be too much, so I just did 50. In conclusion, 50 was effective enough. I asked them to put it toward the back because I was worried about my cheeks getting sunken, but I still got a little sunken . But I don't have much cheek fat, so I'm 50% satisfied... I think you should never get 100 units.
