Excess Skin

So in the past couple years I've been losing weight, about 90 pounds total so far. For the first time in two years I got my body fat percentage, and it was down from 33% to 19. I realized the fat I thought I had was mostly just excess skin from a kid who used to be as fat as me and is now a bodybuilder and is ripped, who's body fat was apparently 13.

My question is how do I get rid of the extra skin from my midsection, upper arms, thighs, and butt? The other parts of my body are either filled out (calves, back), other parts I am pretty close (chest, forearms). Also is there any way to get rid of stretch marks? I used to be extremely embarrassed of them, but now they're more of an inconvenience.

Gaining muscle, losing weight a bit slower, trying some skin cream for the stretch marks, ensuring good hydration etc during the day, enough nutrients (monounsaturated and omega-3s in particular) and see how that goes.

Excess skin the same thing is happened to me and i want to get rid to this, it really makes me bad to look and spoil my beauty, have you any idea friends what is the best way to away this. I want to let you know its also make my mouth big like huge age man.
