I lost 95 lb and gained back 25 and by the time I gained that 25 back, all the loose skin had nicely filled out.
I am now attempting to complete the 100 and then some, and I'll stay in that weight zone for a long time with good food habits. Hopefully the loose skin will also get eaten by my body over the course of the "maintenance" phase.

There are some youtube videos about it.

Losing weight makes you look younger anyway, so loose skin or not, you look better. My wife commented that I looked better @ 165 on the rebound than I did on the first pass. TBH, I don't recall the first pass @ 165 and how I looked, It went so fast. but subsequent 165's have been when I have worked out and muscled up to 165 from 150 and I should say I did look damn good.

Thanks.
