You may be experiencing what is called “stretch marks”. Stretch marks are caused by rapid growth in the womb, or due to sudden changes in hormone levels during puberty. They usually appear as red lines or streaks on the skin, and can be permanent. There are treatments available to help reduce their appearance, but it's important to consult with your doctor if you're concerned about them.
