Are Stretch Marks Genetic?

Are stretch marks genetic? Stretch marks are a common skin concern but nothing to be worried or ashamed about. Up to 90% of women have them. The question is, are stretch marks hereditary? In other words, if your mom, sister, or aunt has stretch marks, will that mean you’ll get them too? Here’s everything you should know about stretch marks and whether or not they’re genetic.



What are Stretch Marks?

Stretch marks, scientifically known as striae distensae, are deep tears below the skin’s surface that typically appear as parallel lines that vary in color from silvery white to dark purple. They normally appear due to rapid stretching of the skin which can occur during growth spurts, pregnancy, or rapid weight gain. Stretch marks can appear almost anywhere but are most commonly found on your boobs, butt, thighs, and stomach.

The development of stretch marks is closely related to the structure of connective tissue, particularly collagen and elastin fibers. Connective tissue provides support and structure to the skin, giving it elasticity and strength. When the skin experiences rapid stretching, the normal production of collagen and elastin may be disrupted, leading to the formation of stretch marks.

Yes, stretch marks are genetic. If your mom or sister had them, you’re more likely to get them too. Genetics plays a huge role in most conditions—stretch marks included. Even the American Academy of Dermatology Association (AAD) have confirmed that stretch marks can be hereditary. So, if members of your family get pregnancy stretch marks, there’s a high chance you will too.

Stretch marks occur when your skin expands faster than the fibers in your skin (collagen and elastin) can accommodate. While the level of skin stretching is different for everyone, it’s likely that if your parent developed stretch marks, it’s because their skin’s elastic fibers are less able to accommodate rapid growth.

Collagen is a protein that provides structure and strength to the skin. Genetics influence the production and quality of collagen in your skin. If your family has a history of skin conditions or a tendency to develop stretch marks, it could be related to the genetic component affecting collagen production.

Skin elasticity also determines how well your skin can stretch and then return to its original state. Genetic factors can impact the elasticity of your skin, making some individuals more prone to the development of stretch marks than others.


Common Causes of Stretch Marks

Are stretch marks genetic? Will I get stretch marks if my mom did? Yes, and yes. Research shows that stretch marks can be hereditary. That being said, it’s worth being aware of the other factors that can increase your risk of stretch marks.


1: Rapid Growth: The most common cause of stretch marks is rapid growth or stretching of the skin, which can occur during pregnancy, adolescence, or due to rapid weight gain. Pregnant women are highly likely to develop stretch marks due to the skin stretching that occurs during pregnancy.

2: Hormonal Changes: Hormonal changes, particularly an increase in cortisone (a hormone produced by the adrenal glands), can weaken the skin’s elasticity and contribute to the development of stretch marks.

3: Genetics: Genetics also play a role in determining skin characteristics, including its elasticity. If there’s a family history of stretch marks, you may develop them too.

4: Certain Medical Conditions: Conditions such as Cushing’s syndrome and Marfan syndrome can increase the likelihood of stretch marks.
