Just want to add to the above advice...

Stretch marks aren't only related to being over weight. They can occur when you get taller or start to develop hips/breasts during to puberty. (Your body is growing faster than your skin can stretch at these times, that's why they occur)...Anyways, just about everyone has them. You can use bio oil, like mentioned to help them fade. Also, make sure you use a good body lotions every morning and night, and after baths/showers, to help your skins elasticity. That will help prevent future ones from happening!

If you think you need to lose weight, look into adding more exercise to your routines. Try going for runs or walks, or even riding a bike around your neighborhood. Make sure you drink a ton of water, and that you're eating a healthy diet.

As for your stretch marks, you can minimize their appearance and sometimes get rid of them by using lotions or creams containing coconut oil or aloe vera. Applying lotion can also prevent more stretch marks from occurring.

you got them because your body grew at a certain time where you werent ment to grow at tat time.
BIO OIL...I think thats what its called
