Old thread but replying because I am bored. I am 21 and I am planning a tummy tuck for when I lose all my weight. I know there will be alot of loose skin. I am going to be loosing 100 lbs and I already have an odd stomach from my pregnancy. Im just going to make sure that I can lose as much as I can 1st plus they are expensive so I will be saving up beforehand.

Your right surgery should be a last resort. This may or may not work on you but there is a strong chance it will.
Get a huge bottle or sorbolene and rub the whole thing into your belly/body. You may need to wipe / rinse / wash it off a few times too.
Often, the sorbolene simply rubs away things like this: thick, hard, non-elastic skin, big belly, areas that are hard to shave / dark hairs. Seems to be miraculous for some people.
May sound too good to be true but it really can work lilke that, often scaly fungal skin build up (dandruff) appears to look and feels like normal skin, however it is not and can be removed with sorbolene.
Love handles, fat hips, rubbing thighs, rashes, exma, pimples, inflamed angry skin, baldness.
Sorbolene is so cheap and available even from supermarkets. However it is recommended to choose a trusted brand if you are going to use a very large amount.
Even up your skin tone, remove excess folds, freshen your skin, rub off the 'age' that builds up over time.
To help the process or removal of this unsightly old skin and help create a new and more healthy floral balance you may also try using a product such as selenium or tee tree oil. Good luck!

i cant really 100% tell from the pictures but i think its a bit of both. maybe just a bit of fat and mostly skin.

after my pregnancy i had fat and skin hanging as well.. i did a lot of cocoa lotioning, and massaging.. drank plenty plenty plenty of water... and worked out a little bit.. just some crunches everyday... i can say that my tummy is not hanging anymore and all of this really helped like in within 3,4 months.. but you have to stick with it. lotion everyday and massage everyday... do everyday some exercise and if its just 5 minutes..

good luck

Heya, I lost somewhere around 100 pounds and i can say its probbaly loose skin, before making any choices of talking to my parents of the option of the surgery i waited for a few months, mine shrunk ALOT when im wearing panties or a swimming suit you cant even tell. Make sure to put lotion on it EVERY day, when you wake up and go to sleep, dont forget to do core exercises and remember, everyone is differant. If you cant deal with it then id see a plasti surgon but if your willing to wait awhile you may be pleasantly surprise, I dont think it ever fully goes away. but with gaining muslce it may help. Since you lost the weight with mostly crash diets you may have more fat then you think. Stay strong! you've done AMAZING if you need anything , even just a friend to talk to message me!
