I didn't have visible cellulite until I hit 42. I have mild cellulite on upper thighs and butt. I am 5'8" and a size 4, so I can't lose weight to reduce its appearance. I exercise 5-6 times a week; my water intake is adequate and my diet is very healthy (no meat, no fast food, no highly processed food, no sugar).
After five sessions, absolutely no difference in appearance. The place I went to offered me three extra sessions at no cost. So now after eight sessions, I can still say absolutely no difference.
