Ladies with cellulite: What have you done to combat it?

I have been affected by cellulite all my life. It was on my whole legs, butt, stomach and back. Last year I started with the gym + eating better and I lost 7-8 kgs. It has kind of improved in the back and legs area. But the tummy and butt area are still as bad as from a year ago. I don't think mine is genetic because no one in my family has it (that I know of).
Any methods that you found effective in reducing your cellulite? Or is the tummy/butt area even possible to improve on?
