Stretch marks, or “striae,” are one of those skin changes almost everyone deals with at some point. They often pop up during pregnancy, rapid weight changes, growth spurts, or even intense exercise. While they’re totally harmless, many people want to know why they form—and if anything can be done to minimize them.

Why Stretch Marks Form

Stretch marks happen when skin stretches faster than its ability to adapt. The sudden pulling disrupts collagen and elastin fibers, leading to streak-like scars. They usually start red, purple, or dark brown (depending on your skin tone) and fade to silvery or white lines over time.

Who Gets Them?

  • Pregnant women (especially during the third trimester).
  • Teenagers going through growth spurts.
  • Bodybuilders or athletes gaining muscle quickly.
  • Anyone with rapid weight gain or loss.

Can You Prevent Them?

Keeping skin moisturized, staying hydrated, and avoiding rapid weight fluctuations can help. But genetics also play a big role—if your mom or siblings had stretch marks, you’re more likely to get them too.

What Helps Improve Them?

While they may never disappear completely, treatments like microneedling, laser resurfacing, or radiofrequency can dramatically improve their texture and appearance. Medical-grade skincare with retinoids can also help stimulate collagen and smooth the skin.

The Takeaway

Stretch marks are incredibly common and nothing to be embarrassed about. If you’d like them softened or less noticeable, today’s technology offers safe and effective solutions.
