How to get rid of excess skin?

[brutiepook]

Ok so, I weighed 80kg while i was a preteen, now i weigh less and have fucking excess skin. I want to remove it at 18 but holy fuck is it long to wait (im 16). Are there any softmaxxes i can do (any sort of injections included)? Literally hate myself so much for it
