Stretch marks are streaks that appear on the skin as it stretches to accommodate a growing bump, most commonly on the belly, breasts, hips, and thighs. They happen when the skin stretches faster than its natural elasticity can accommodate, causing small tears in the deeper layer of skin.

What is Stretch Marks in Pregnancy?
Stretch marks are streaks that appear on the skin as it stretches to accommodate a growing bump, most commonly on the belly, breasts, hips, and thighs. They happen when the skin stretches faster than its natural elasticity can accommodate, causing small tears in the deeper layer of skin.
They're extremely common in pregnancy — affecting a large majority of people to some degree — and are largely determined by genetics and skin type rather than anything that can be fully prevented. They typically fade from reddish or purple to a lighter, silvery colour over time after birth, though they don't usually disappear completely.
02 · Understand
Clinical context
Genetics play the biggest role
Whether and how much someone develops stretch marks is largely determined by genetics and skin elasticity, which is why some people develop many and others very few, regardless of weight gain or skincare routine.

Practical steps
No Cream Can Fully Prevent Stretch Marks
While moisturizing can help keep skin comfortable and may ease itching as it stretches, no product has been proven to reliably prevent stretch marks from forming, since they're largely determined by genetics.
- 1Moisturize regularly for comfort.This won't prevent stretch marks but can help soothe itchy, stretching skin.
- 2Stay hydrated.Good hydration supports overall skin health, though it won't prevent stretch marks on its own.
- 3Maintain steady weight gain where possible.Gradual weight gain, as guided by your maternity team, can sometimes reduce the severity, though it's not guaranteed.
- 4Be kind to yourself about it.Stretch marks are an extremely common and natural part of pregnancy, not a flaw to fix.

BarnMD Bottom Line
Stretch marks are a normal, common part of pregnancy and typically fade significantly over time.
They're determined mostly by genetics — there's no need to feel that any particular cream or routine failed to prevent them.
