i have just dropped about 30lbs in a few months and i can now notice that i have excess skin, and the excess skin is preventing my abs from really showing, and is evident on my arms legs and around my mid region. I am now 190lbs and 21 yrs old down from 220lbs which i was for only a few months after about 205-210 for about a year. Will my skin shrink back to normal? and how long should i expect for that to happen?
