Is it normal to have stretch marks at 15?
Yep.Totally normal
Yes—stretch marks are common at 15. They often appear during growth spurts and usually fade over time, though they may not disappear completely.
Your body can grow faster than your skin adjusts, especially during puberty, so stretch marks can show up on places like your thighs, hips, breasts, or back. They’re common in teenagers of all genders and body types—not a sign that you’ve done anything wrong.
They may start out pink, red, purple, or darker than your skin, then gradually become lighter. You don’t need to treat them, but if they’re appearing suddenly in large numbers or you’re worried about them, you can bring it up with a healthcare professional.
