Stretch marks are a normal part of puberty for most girls and boys. When a person grows or gains weight very quickly (like during puberty), that person may get fine lines on the body called stretch marks. Stretch marks occur when skin is pulled by rapid growth or stretching. Although the skin is usually fairly elastic, when it is overloaded, the normal production of collagen (the major protein that forms connective tissue of the skin) is disrupted.

I have done some research on stretch marks, i dont think cream works, the cream only makes it appear smoother but dont take them out. stretch marks can be remove only by laser or surgery. i also have some on my butt, but thats gonna stay there because i dont wanna do surgery on it.

I have heard that laser treatment gets rid of stretch marks.
