Trust me, loose, saggy skin is way better than fat... for both health and estetics ...
In my case, refirming lotions and exercise (weight training) helped... also, give it a year to your body to adjust once you´ve lost the weight, once I lost the weight I had a lot more saggy skin, a year later with more or less the same weight (doing weight training), the skin had improved considerably... I still have saggy skin in some areas, arms and legs specially bother me, but it´s way way WAY better then when it was fat !!
