I HAVE stretch marks AND IM ONLY 12!!! whats going on?!

This is completely normal and it happens to almost everyone, your just growing your not getting old! When you grow quickly your skin stretches and causes stretch marks, I had the same thing happen to me on my boobs and my thighs..it's just typical results of puberty. Use some cocoa butter or other lotions to prevent anymore stretch marks and to help make the ones you have be less noticeable.

4'5 and 120 pounds is not a healthy weight to be. That if why you have stretch marks - you need to control your weight.
Not to be mean, but that's what it is.

You're not getting old. Go to the store and buy some stretch mark lotion. Put it on the stretch marks every single night before you go to bed. Petty soon you won't even be able to see them!

Completely normal... your growing
The redness will fade and over the years the scars will too. You can help them on there way by using products like Bio-Oil, but for now your basically stuck with them.

lol that sucks for the both of us though cuz im 13 just turned 13 last week butanyway i have stretch marks too lol i thought i was alone

you are over weight i20 is too much for your height,and they never go away
