As far as I know, cellulite treatments reduce the appearance of cellulite, they don't get rid of the fat. Even the Shape article says that:

THE SUPER MASSAGE: ENDERMOLOGIE
How it works A technician rolls a vacuumlike hand piece over your backside while its suction and motorized rollers suck up skin, delivering a serious deep-tissue massage. Some doctors believe this action only swells the skin's surface, temporarily camouflaging dimples, says Cap Lesesne, M.D., a plastic surgeon in New York City.
and here is a snippet from another one of the treatments

COOL LASER: TRIACTIVE
How it works A hand piece resembling a large flashlight massages skin while sending infrared energy below the surface. ... David Goldberg, M.D., a spokesman in NYC for the American Society for Dermatologic Surgery, says it simply swells the skin's surface slightly better than Endermologie.
And I've heard the best thing to help smooth the skin is actually caffeine which is why all cellulite creams have it. I've seen things where you can do a 'do it yourself' caffeine compress. It'll reduce your visible cellulite but the fat is still there and if you stop treatment, it'll reappear.
