The weight and stress on the skin in those areas are too severe for these problem areas. Those treatments will only yield a benefit in less stressed areas like the face. Laser or light or radio-frequency therapy are not the correct 'fix' for difficult problems areas. Diet, exercise, and ultimately surgery will achieve the best improvements. I know that is not as exciting or glamorous as a quick treatment but this is reality. Save your money for better more permanent options. Your best solution is a plastic surgeon.
