Stretch marks can be the enemy of a teenager's growing body 1. These reddish-purple lines can form when the skin stretches beyond its normal limits and scar tissue forms in its place. They are common in areas where you may experience growth spurts, such as the hips, thighs, buttocks and abdomen. Although the marks fade over time, they are permanent. Take action to prevent stretch marks from forming in the first place 1.
