Tighten my skin?

Im 15 years old about 5'7.. when i used to live where i used to live my max weight got to 184.. i dropped down to about 170 total before i ended up moving as i became more active, then i moved next door to my old buddy in a dif town.. where im livin now, and me and him wud always be out and about, biking excersising the whole 9 yards so i finally got to 140.. after i lost all the weight i thought i had a chance to actually have a nice body so i didnt want to just be thinner i wanted to get abs so i worked on those, sit ups, pushups, chinups on my chinup bar, and this routine from 6 second abs. I now have a decent chest, and a 6 pack but its all hiding under my skin and fat. I can feel it perfectly, every detail to my abs and theyre visible as well, you can see the texture but just not very defined because i still have some loose skin from being overweight before, and idk if i still have to fat to shed. My skin isnt like saggy but its loosER cuz i used 2 be fat. How can i tighten it??

Tighten my skin?
it will tighten on its own. your still young it will get tighter pretty quickly. you still need to lose some fat, so keep doing what your doing and your abs will be clear as day. i would suggest trying to fill up some of that lose skin with muscle. consider weight training.
Reply:give it time. it will return. when you are young your skin is very elastic. it just takes longer than the rest of you to resize itself. it could take a year or more. stay fit. and congratulations... good for you.

Reply:Sadly loose skin is very difficult to get rid of but you have a better chance of it shrinking because you are young. It would be much harder for an older person to get rid of loose skin. Eat a healthy diet, and keep working out and take care of your skin and maybe your skin will tighten up. It may take a few years though. Good luck and congratulations on your weight loss :)
Reply:I bet you don't like to drink skim milk, and I bet you lost the weight fairly quickly, cuz that's what skin will do. Just give it time, it will tighten up. Getting the right kind of nutrition helps the skin when you are loosing weight. You've done a great job! Hang in there!
