Is it normal to have stretch marks at 13?
Yep.Totally normal
Yes, stretch marks are common at 13, especially during growth spurts in puberty. They’re a normal skin change and don’t mean anything is wrong with your body.
Your body can grow quickly during puberty, and skin sometimes stretches faster than it can adjust. Stretch marks can show up on places like your hips, thighs, chest, or back, and genetics can play a part too.
They often fade over time, though they may not disappear completely. Having them is normal at your age—and they’re not a sign that you’ve done anything wrong.
