Understanding Pregnancy Stretch Marks: Causes and treatment - Allow Yourself

Brie Bacon • February 8, 2025

Stretch marks, also called striae, are common skin changes that occur during pregnancy and leave indented streaks on areas such as the abdomen, hips, or thighs. Around 90% of pregnant women experience these marks during their last trimester, so they are not uncommon.

These marks appear when the skin stretches too quickly due to factors such as pregnancy, rapid weight shifts, or hormonal changes. Genetics and conditions like Cushing syndrome can also increase your chances of getting them.

While stretch marks are harmless to your health, many people find them unsightly and want to get rid of them for strictly cosmetic reasons. Luckily, there are a variety of treatment options that range from topical creams with ingredients like tretinoin, to more advanced procedures like laser therapy.

You can also use preventative methods to avoid stretch marks, like keeping your skin hydrated and avoiding any sudden weight changes. Keep reading to hear more about the causes, treatments, and prevention tips for stretch marks in this in-depth guide!

Key Takeaways

  • Stretch marks occur when skin stretches too quickly due to pregnancy, weight changes, or genetics. They commonly affect areas like the abdomen, thighs, and breasts.
  • Rapid weight gain or hormonal shifts during pregnancy can weaken skin elasticity, causing stretch marks. A family history of stretch marks can also increase your risk of getting them.
  • Treatments include topical creams like hyaluronic acid and laser therapy that can improve appearance. Home remedies including oils and hydrating skincare can also help.
  • Preventing stretch marks involves gradual weight management, maintaining hydration, and using preventive skincare products rich in vitamin A and other natural ingredients.
  • While treatments may reduce their look, stretch marks rarely fully disappear. Prioritizing healthy skin care supports long-term results.


What Are Stretch Marks?

Stretch marks are streaks or lines that appear on the skin when it stretches too quickly due to weight gain, pregnancy, or other reasons. They often start as red or purple marks and fade to lighter shades over time.

 Definition and appearance

Stretch marks, also called striae, appear as indented streaks on the skin. Depending on your skin tone and type, the marks may show up in colors like red, pink, purple, blue, or even black. Over time, they may fade to a lighter shade or develop into a shiny silvery-white color.

You might notice them more frequently during pregnancy or rapid weight changes when your skin stretches quickly. They commonly affect areas of the body such as the abdomen, upper arms, thighs, and breasts.


Early stretch marks often feel itchy because the connective tissue below the lines is struggling to keep up with growth.

Common areas affected

Stretch marks will often appear on your abdomen, especially during pregnancy. Pregnant individuals commonly notice them in the last trimester as their skin stretches to accommodate a growing baby bump.


These marks also develop on breasts due to hormonal changes or breastfeeding.

Hips, thighs, and buttocks are other common areas affected by rapid weight gain and growth spurts. You may even see them on your arms and lower back if collagen fibers break down from excessive stretching.

Causes of Stretch Marks

Stretch marks often develop when your skin stretches quickly and it struggles to keep up with the rapid growth. Factors like changes in the body or genetics can play a role in their formation as well.

Rapid weight changes

Rapid weight gain or loss can also stretch your skin, leading to visible marks called striae. If you lose or gain too much weight quickly, the skin struggles to adjust, which may cause reddish-brown lines on areas like your thighs, abdomen, and arms.

These changes are common in people with fluctuating body mass index due to diet shifts or health conditions.

Anabolic steroid use can also trigger these marks by weakening the collagen in your skin. To minimize this risk and support healthy skin elasticity, focus on gradual weight management instead of making sudden shifts.

Incorporating hydrating products like olive oil or topical preparations enriched with vitamin A into your skincare routine can add nourishment and also increase resilience.

Pregnancy and hormonal changes

Pregnancy causes your skin to stretch quickly, especially during the second and third trimesters where more skin stretching is happening. Hormonal changes, like higher cortisol levels, weaken skin elasticity and can make pregnant women more likely to develop these unwelcome reddish-brown or purple marks.

Women of a younger age have increased likelihood of getting stretch marks during their early pregnancy. A family history of stretch marks may also play a role in whether or not they appear. Using preventative products like Allow Nourishment Udder Delight Face and Body Tallow Cream can help soothe itchy skin and support hydration throughout your pregnancy journey.

Stretch marks affect 50%-90% of individuals during pregnancy.

Genetic predisposition

Your genes will also play a significant role in whether or not you develop stretch marks. If your family members have them, you're more likely to experience similar skin problems like these too.

Conditions such as Cushing syndrome and Marfan syndrome, which are both genetic disorders, may also increase the risk of stretch marks due to changes in skin elasticity caused by hormonal imbalances or tissue growth.


Another factor that will influence how visible your stretch marks will be is your skin type and color. Those with lighter skin tones might see reddish-brown marks initially, while darker skin tones could notice a deeper contrast when compared to their natural color.

Using preventive skincare products like creams found at Allow Nourishment may help improve hydration and strengthen your skin over time.

Treatment Options for Stretch Marks

Let's explore several ways to improve the appearance of existing stretch marks. Depending on your skin type and the stage of your stretch marks, you may require different treatments.

Topical creams and oils

Using topical creams and oils are a non-invasive way to improve early stretch marks. These products work best when used consistently on newer marks. Here are a few ways to incorporate them into your routine:

  1. Use hyaluronic acid to hydrate the skin and reduce the look of reddish-brown marks and improving elasticity.
  2. Apply tretinoin cream to boost collagen production in the affected areas. Studies show it can improve early pregnancy stretch marks within six months.
  3. Avoid relying on oils like cocoa butter or almond oil, as research shows little evidence that they are effective for treating stretch marks over the long term.
  4. Invest in glycolic acid treatments, which help exfoliate and renew the skin’s surface gently.
  5. Include vitamin D products in your skincare routine to support overall skin health during or after the first trimester of pregnancy.

Laser therapy and microdermabrasion

Laser therapy and microdermabrasion are an effective way to help reduce the appearance of stretch marks, however they may take time, be costly, or have potential negative side effects.

  1. Laser therapy uses focused light to target stretch marks. It stimulates collagen production under the skin, which promotes healing. Results from laser skin resurfacing can last for years, but some side effects include swelling or pigmentation changes in treated areas.
  2. Microdermabrasion works by exfoliating your skin with tiny crystals. This improves texture and minimizes stretch marks over time. You may notice results within weeks to months after consistent treatments.
  3. Both options require multiple sessions for visible improvements. Microneedling, often combined with these treatments, might need 3-6 sessions, with results that are noticeable in 4-6 months.
  4. Consulting a healthcare provider will ensure a safe treatment plan. They can offer professional advice suited to your specific skin condition and talk over any risk factors with you.

Next, let's discover how home remedies and lifestyle changes can effectively support the reduction of stretch marks.

Home remedies and lifestyle changes

Home remedies and lifestyle adjustments can improve the appearance of stretch marks. These options are affordable, simple, and easy to include in your daily routine. Try using some of the following tactics to improve the look of your skin:

  1. Apply natural oils like coconut oil or olive oil to keep your skin hydrated and soft. Massage the area gently to boost circulation.
  2. Eat a healthy diet rich in citrus fruits, zinc, vitamins A, C, D, and protein to support skin repair. This also promotes overall skin health.
  3. Drink plenty of water throughout the day to stay hydrated. Limit caffeine intake since it can dry out your skin.
  4. Use Allow Nourishment creams as a natural skincare option for added moisture. They contain beneficial nutrients that enhance skin elasticity.
  5. Exercise regularly to promote better blood flow and strengthen your skin’s structure. Activities like yoga or walking are great for circulation.
  6. Avoid rapid weight gain or loss by maintaining a healthy weight over time. Smaller, controlled changes reduce strain on your skin.
  7. Take warm baths with Epsom salts occasionally to relax muscles and soften your skin texture naturally.
  8. Gently exfoliate using chemical peels or scrubs suited to your skin color for improved tone and texture over time.
  9. Prioritize mental health by managing stress levels through meditation or breathing exercises since stress can impact the hormonal balance of the adrenal glands.
  10. Wear comfortable clothing during pregnancy, especially in the second trimester or seventh month, to reduce friction on sensitive areas prone to stretching.

Preventing Stretch Marks

It's easy to take simple steps to keep your skin healthy and reduce the chance of future stretch marks forming.

Maintaining healthy skin hydration

Drink plenty of water daily to keep your skin hydrated from within. Proper hydration strengthens elasticity and helps prevent reddish brown marks caused by skin stretching. Avoid excessive caffeine intake, as it dehydrates the skin.

Use quality skin products from Allow Nourishment to lock in moisture and hydrate your skin naturally. Coconut oil or shea butter can also provide extra hydration for dry areas. Additionally, staying active boosts circulation and allows nutrients to more easily nourish your skin.

Gradual weight management

Keeping your weight changes gradual can make a big difference in helping to prevent stretch marks. Rapid fluctuations in weight cause the skin to stretch quickly, leading to more of these marks popping up. By focusing on slow, steady weight gain or loss, you allow your skin time to adapt while it continues maintaining its elasticity.

Integrate a balanced approach that supports long-term women's health. Pair regular exercise with nutritious meals for the best way to manage weight over time. Medical professionals often suggest avoiding extreme diets or drastic changes that can create stress on your body and skin.

Use of preventive skincare products

Using preventive skincare products can help minimize stretch marks before they form. Products like hyaluronic acid improve skin elasticity by keeping it hydrated. Tretinoin, a derivative of vitamin A, promotes collagen production and may reduce early signs of stretch marks.


Pregnant people, or those breastfeeding, should avoid tretinoin and consult their doctors for safer options.

Opt for natural alternatives to keep your skin supple and nourished. Allow Nourishment offers effective tallow-based creams that hydrate deeply and support long-term skin health.

Conclusion

Stretch marks are a normal part of life and affect many people. While treatments can help reduce their appearance, they rarely disappear completely. Focus on prevention and healthy skin care to minimize your chances of developing them.

Choose options that fit your needs, and consult a doctor if you're unsure. Taking care of your skin is always a good idea over the long term!
