CoolSculpting did absolutely nothing for my knees, neck and chin

I had 2 rounds on my knees (another place) and 1 on my neck and chin. It did absolutely NOTHING, I definitely wouldn’t waste money on it again. I am not in shape, so I don’t know how it would work on a person that was and just had a tiny amount of fat in a small area. Although I should of saw a tiny result on my chin and did not.
