Worried :(

You are young and that is the best thing to help against loose skin. So lose the weight while you are young!

Best things you can do:
1. Stay hydrated.
2. Stay moisturized. Lotions with cocoa butter, CoQ10, or collagen elastin help. Luv the collagen elastin lotion from St. Ives!
3. Don't yo-yo diet, your skin can't keep up. Same with rapid weightloss. Don't aim to lose more than 2 lbs a week.
4. Massage helps.
5. Most importantly, exercise! Especially strength training helps with loose skin. Don't wait till you reach goal to pick up some weights.

I lost nearly 70 lbs when I was 30 and didnt have any extra skin. Gained it back but I have lost nearly 60 lbs this time around and I still dont have loose skin yet. And I'm 35. So I think you'll be fine losing 80 lbs at 21 years old.

I lost 80 lbs in 9 months at age 41 and don't have any loose skin. . My good friend lost the same amount of weight in 12 months at age 28 and she has tons of loose skin. We followed the same exercise schedule - bootcamp 3 or 4 days a week. A lot of whether your skin bounces back is genetics.

Loose skin is a result of excess fat still under the skin. If you continue to get in shape, it will reduce.

I've lost 85lbs, I have some loose skin, particularly on my arms and lower abdomen. I am about a decade older than you. Genetics will play a big part in whether or not you get it, and I'm sure your age will be an advantage. I've never heard any definitive answers on things that definitely work, but the things that seem to be mentioned over and over are to lose weight as slowly as possible (not a bad idea anyway to be honest), to keep well hydrated, to strength train as you lose and to keep the skin moisturised. Bio oil by Bioré is one that I've seen recommended for stretch marks and loose skin.

Mine hasn't improved very much so far, but I've also heard people say that time can work wonders, and that a couple of years after reaching your goal, things should have improved.

Really, my loose skin isn't that bad, and it's only visible to most people if I wear strapless tops. I have to say though, even if it was a lot worse, losing the weight is still absolutely 100% worth it. Work on that confidence now! I know it's a cliché, but confidence really does come from within. Loose skin will only drag your confidence down if you let it. You're a beautiful young woman, and you're going to rock that new body. Build up your confidence to go with the body, and people won't even notice the flaws. I know it sounds easier said than done. I read on your profile that you want to like what you see in the mirror. For many years, that's what I really wanted too. Yesterday, I was looking in the mirror, and I was so busy admiring the definition in the top of my upper arms, that I didn't remember the loose skin underneath. I would quite happily go out showing my arms off, and knowing that they look just as good (if not better) than a lot of other people's.

I didn't always feel that confidence, and I know that some of it comes with age, and not being surrounded with so many image-obsessed young things, as maybe you are at 20. Something to think about though, and definitely don't let it put you off losing the weight, or showing off your body (if that's what you want to do!) as you get more comfortable with it.
