Is it normal to have stretch marks?
Yep.Totally normal
Yes—stretch marks are very normal and common. They can show up when your skin stretches quickly, and they often fade over time but may not disappear completely.
Stretch marks can happen during puberty, pregnancy, weight changes, or muscle growth—basically, whenever your body changes faster than your skin can keep up. They may start out pink, red, purple, or darker than your skin tone, then gradually lighten.
Lots of people have them, and they’re usually harmless. You don’t need to do anything about them unless you simply want to; creams and oils generally can’t erase them, despite what the labels promise.
