Will my stretched skin tighten on its own or will I need surgery, following weight loss? (photo)

Thanks for sharing photos.  You are very young and should have ability to have some skin retraction with weight loss.  Often a patient in their 30's or older has already started to lose elastic recoil in the skin, especially if they had a surgical weight loss procedure like gastric bypass, or lap band.It doesn't appear that you have too much extra skin and undergoing a body lift would likely be too aggressive of a procedure for you. A visit with board certified and experienced plastic surgeon in your area for a full and complete evaluation is recommended

From the photos you submitted, it doesn’t appear that you
have too much excess skin.  You have some
pale stretch marks where you lost weight. Stretch marks are difficult to treat without
excision, and it does not appear that you have enough excess skin to
remove.  There may be other non-surgical
options available for skin tightening and pale stretch marks such as dermal
rolling or broad band light therapy that may help.  However, I would recommend that you consult
with a board certified plastic surgeon to explore all your options.
