Will my Skin Recover 100 Percent After Weight Loss?

When I was 21 I starting taking medication for ocd which I was on for 2 years trying different medications but nothing worked. I am 6'2 and my weight went from 155 to 178 and now I'm off my weight is coming off as well and I plan to go back down to 155. My question is, did I mess up my skin from that weight gain or will my skin be totally fine, back to normal and as tight as it was before?
