Cannot cure

actually i think its just some loose skin.maybe u lost alot of weight fast.
if thats the case then it will get back to normal slowly.
ur skin will stretch to fit ur current body size.

if it is really cellulite then u should probably try to reduce excess body fat percentage
and also some strength/resistance training might help.
I say might because cellulite is a skin problem not a fat/weight problem.
Dieting hard can make it worse so you should definitely avoid that.
Some people are just more predisposed to getting it due to genetics,hormones or even race.
So there isn't any magic treatment that will make it disappear.
Basically just exercise,eat healthy and take care of your skin and it should show results.just not immediate.
