All About Pregnancy Stretch Marks

Pregnancy stretch marks are a natural result of your skin stretching to make room for your developing baby and uterus. Not everyone gets them, but if they do accompany your pregnancy, stretch marks tend to fade over time. Either way, they’re a reminder of your sweet baby and a badge of honour for all the work of being pregnant! Read on to learn all about pregnancy stretch marks, including why they’re a natural part of pregnancy, what you can do to soothe your skin as it stretches, and how to get rid of them.

What Are Pregnancy Stretch Marks and What Do They Look Like?

Pregnancy stretch marks (also called striae) are natural, with more than 50 percent of pregnant bodies experiencing them. Stretch marks are not exclusive to pregnancy, however; men and women, whether pregnant or not, can develop these markings whenever the skin stretches rapidly.

Do you ever ask yourself, “Why are my stretch marks purple?” Well, stretch marks can appear in all sorts of colors, including pink, red, purple, or brown, depending on your skin pigmentation.

During pregnancy, stretch marks can appear on your stomach, breasts, buttocks, thighs and upper legs, hips, and arms. As stretch marks fade, they may change colors, appearing silvery or white, or even darkening.

What Are the Causes of Stretch Marks During Pregnancy?

Simply put, stretch marks may appear on your pregnant belly and body because your skin stretches to make room for your developing baby. The stress on your skin can cause these marks, which are not harmful. Contrary to popular belief, these streaks aren’t usually a result of normal pregnancy weight gain but rather your skin stretching while hormone levels shift. Of course, weight gain can also cause the skin to stretch, but even those who gain a minimal or modest amount of weight during pregnancy may experience stretch marks.

There are two main factors that can impact pregnancy stretch marks:

Hormones. Changes in hormone levels during pregnancy contribute to the development of stretch marks. During pregnancy, your adrenal glands produce the hormone cortisol. As cortisol levels naturally increase, the elastic fibres in your skin weaken, and as your skin stretches, it results in stretch marks.

Heredity. Genetics are also a factor in whether you get stretch marks during pregnancy. If you experienced stretch marks at a younger age, such as with a growth spurt that stretched your skin during puberty, or your family members have them, it’s more likely that you’ll get those red, purple, pink, or brown streaks during pregnancy, too.


At What Month in Pregnancy Do Stretch Marks Appear?

When should you expect to see stretch marks during pregnancy? Every pregnancy and body are different, but stretch marks are most likely appear sometime in the second half of your pregnancy. At this point, your baby bump starts to grow bigger and more quickly, putting further stress on the skin.

Some parents-to-be will start to see these markings in the second trimester, whereas others may not notice them until the last few weeks of the third trimester. And remember, some don’t experience stretch marks at all!

How Common Are Pregnancy Stretch Marks?

As mentioned above, more than half of pregnant people develop stretch marks, meaning there's a decent chance of having no pregnancy stretch marks. Likewise, it’s also possible to experience minimal pregnancy stretch marks on your stomach, breasts, thighs, or other parts of your body.

Regardless, there are a few risk factors concerning these marks:

  • Being pregnant at a younger age

  • Rapidly gaining weight during pregnancy

  • Using corticosteroids during pregnancy

  • Having certain genetic disorders (Cushing's syndrome or Marfan syndrome).

If you fall into any of the categories above, you have a higher risk of developing pregnancy stretch marks.

How to “Prevent” Stretch Marks During Pregnancy

Many people want to know how to prevent stretch marks during pregnancy, but unfortunately, there’s nothing you can do to avoid them altogether. Stretch marks develop deep within your skin, specifically in connective tissues, so you can't prevent them from occurring with any topical or external treatment. Plus, because hormones and genetics are involved, stretch marks are pretty much out of your control.

However, some strategies could help reduce the risk of getting stretch marks and/or minimize their appearance. The key is to take these measures before your belly expands and keep them going throughout your pregnancy.

  • Use lotion or cream daily to keep your skin moisturized. This tactic can also help relieve itchy skin during pregnancy, whether you have stretch marks or not.

  • Stay hydrated by drinking lots of water, which may help keep your skin soft and less prone to stretch marks.

  • Avoid caffeine during pregnancy, which can increase your risk of developing stretch marks.

  • Maintain a healthy pregnancy diet with adequate nutrients. Eating a balanced diet rich in zinc, protein, and vitamins A, C, and D can help promote healthy skin.

Do Pregnancy Stretch Marks Go Away?

Is it possible to get rid of stretch marks after pregnancy and how long does it take for them to fade?

These common questions may arise when you’re still pregnant or when you’ve already given birth and are wondering how to deal with postpartum stretch marks. The good news is that stretch marks will typically fade after pregnancy. Because they’re a form of scarring, the fading will be gradual, though, and they might not completely disappear.

Remember that stretch marks are a common and natural result of nurturing a baby inside your belly. Your body will inevitably change during pregnancy, and that’s expected, necessary, and completely OK. To learn more about how your body might adjust to being pregnant, check out our pregnancy calendar and know that you’re not alone in this journey—every pregnant person goes through it, too!

However, not everyone likes the look of these streaky badges of honour and you’re certainly not the only person asking themselves, “How do I get rid of pregnancy stretch marks?” If you want to minimize or improve the appearance and texture of your stretch marks, always consult your healthcare provider. There are a few treatments to consider, and your provider will be able to recommend what’s best for you.

  • Creams. Although creams can’t prevent the formation of stretch marks on your pregnant stomach (or elsewhere on your body), they may be able to lessen the appearance of these markings after pregnancy. Ingredients such as tretinoin and other retinoids derived from vitamin A can help boost collagen production on the skin’s surface, which may reduce the appearance of stretch marks.

  • Light and laser therapy. Likewise, laser and light therapies can also stimulate collagen production as well as improve elasticity.

  • Microneedling, microdermabrasion, and hyaluronic acid. Other dermatological treatments include microneedling and microdermabrasion, which could promote collagen growth and help the stretch marks blend into the surrounding skin. Applying hyaluronic acid daily may also help prevent and treat the appearance of stretch marks.

If you’re wondering how to get rid of pregnancy stretch marks and are interested in these therapies, consult your healthcare provider. The provider will be able to recommend an appropriate treatment and will let you know if you should avoid anything if you’re currently pregnant or breastfeeding.


Pregnancy stretch marks are caused by stretching of the skin, which can be affected by hormonal levels and genetics. When you're pregnant, levels of cortisol increase, which weakens the elasticity in your skin. As your body grows to make room for your developing baby, the stress on your skin with weakened elasticity can lead to stretch marks. But not everyone experiences pregnancy stretch marks, so genetics are also a factor. Read our article for possible prevention and treatment options.

The Bottom Line

More than half of all pregnant people experience stretch marks, a natural result of your skin stretching to make way for a developing baby and uterus. But pregnancy stretch marks are out of your control, as hormones, genetics, and even skin type can impact whether you get them and influence their overall appearance.

There’s no sure-fire prevention strategy or cure for stretch marks during or after pregnancy. However, you can take a few precautions and opt for certain treatments to reduce your risk and improve the appearance of stretch marks postpartum. For example, during your pregnancy, try to keep your skin moisturized, stay hydrated, and maintain a healthy diet. And if you want to address stretch marks after pregnancy, talk to your healthcare provider about potential remedies, such as retinoid creams, laser therapy, or dermatological treatments.

Try to enjoy your pregnancy journey as much as possible, keeping in mind that normal symptoms such as stretch marks—and even those minor but annoying aches and pains—are a sign that you’re creating a little miracle inside your body. And if you’ve already welcomed your baby into the world, have fun and enjoy all those cuddles!
