[etc] Fat dissolving injection reviews

I got it 4 times a year ago, mainly on my thighs, and this time I went to a different place to get it on my abdomen . The place I went to before injected each one with a hand needle, but this time they put the needles in and injected the medicine from a machine. I never gain weight on my upper body or stomach, but I think I gained weight all over this summer because I ate too well... ㅋㅋ This time, I just went to a cheaper place. It should be effective, but I'm worried ㅠㅠ
