Pregnancy stretch marks, also known as striae gravidarum, are a common and natural part of the physical changes many bodies experience during pregnancy. As a birth doula, I often hear from clients who are curious about these marks, and I want to offer a grounded, evidence-based perspective on what they are and how to approach them with clarity.

## What it is

Striae gravidarum are a type of scar that forms when your skin stretches rapidly. They typically appear as red or purple lines on the skin, most commonly on the abdomen, breasts, thighs, and buttocks. This rapid stretching often occurs during the second and third trimesters as your body grows to accommodate your baby. It’s a very common experience, affecting a significant number of pregnant individuals.

There's a strong genetic component to whether you develop stretch marks. This means if your mother or other close relatives experienced them, you might be more likely to as well. It's simply how your unique skin responds to the incredible growth happening within your body. Just as your body might experience [Round Ligament Pain](/conditions/round-ligament-pain) or [Heartburn During Pregnancy](/conditions/heartburn) as it adapts, stretch marks are another form of physical adjustment.

## What it tends to feel like

For many, stretch marks are primarily a visual change. They generally don't cause pain or discomfort, though some people might notice a mild itching sensation as the skin stretches. The marks themselves can be a source of curiosity or, for some, a shift in body image. It's a reminder of the profound process your body is undergoing, creating and nurturing new life. Over time, these marks naturally fade from their initial red or purple hue to a lighter, silvery-white color, typically within one to two years postpartum.

## What the evidence says helps

When it comes to preventing stretch marks, the evidence offers a clear picture: no topical product has reliably demonstrated prevention in high-quality research. While many products like cocoa butter, vitamin E, and almond oil are widely used and marketed, systematic reviews have found no clear preventive benefit. There has been some positive signal from Centella asiatica (Gotu Kola) extract in smaller trials, but the evidence is still considered inconclusive.

One factor that may modestly reduce the incidence of stretch marks is staying within recommended weight gain ranges during pregnancy. Rapid weight gain is a known risk factor, so focusing on a steady, healthy weight gain pattern, in collaboration with your care provider, is one practical approach. It's about supporting your body's overall wellness, similar to how you might approach managing [SPD — Symphysis Pubis Dysfunction](/conditions/spd) with gentle movement and support.

It's also important to note that some treatments, like tretinoin, can improve the appearance of mature stretch marks postpartum, but these are not safe to use during pregnancy or while breastfeeding.

## Working with your care team

Your care provider is your best resource for personalized guidance throughout your pregnancy. While stretch marks are generally a benign cosmetic change, discussing any concerns you have about skin changes, itching, or your overall weight gain with your OB or midwife is always a good idea. They can offer reassurance and ensure that any symptoms are within the expected range for pregnancy. Remember, you get to decide what feels right for your body and your peace of mind, and having informed conversations with your care team is a powerful step in that direction.
