For many expectant mothers, pregnancy brings not only the joy of a new baby but also a quiet concern about a “little problem”—stretch marks. This skin change can often make women feel anxious and confused. Today's article will take a deep dive into stretch marks, helping you solve the four major questions: What are stretch marks caused by? Can stretch marks go away? What is the best way to prevent stretch marks? Our goal is to help you navigate pregnancy with more confidence.

1. What Are Stretch Marks Caused By?
Stretch marks, medically known as "striae distensae," are essentially a type of skin scar. They appear when the skin "can't keep up" with the body's rapid changes. Our skin is like an elastic garment, and the rapid growth during pregnancy is like stretching that garment too much, too fast.
The outermost layer of skin is the epidermis, beneath which is the dermis. The dermis is rich in collagen and elastin fibers, which act as the skin's "scaffolding," providing its elasticity and resilience. During pregnancy, hormonal changes occur, such as an increase in glucocorticoids, which can weaken these elastic fibers and make them prone to tearing. Simultaneously, as the fetus grows and the uterus expands, the skin on the abdomen, breasts, hips, and thighs is rapidly stretched. The elastic fibers and collagen in the dermis cannot withstand this "stretching pressure" and begin to break.
When this "scaffolding" breaks, various widths and lengths of lines appear on the skin's surface. Initially, they are often reddish or purplish (as broken capillaries show through). After childbirth, as hormone levels stabilize, these lines gradually turn silvery-white or flesh-toned. This is what we commonly call pregnancy stretch marks.
Genetics also play a role. If your mother or grandmother developed stretch marks during pregnancy, you are more likely to get them as well. Additionally, expectant mothers who experience rapid weight gain or have naturally dry, less elastic skin are more prone to developing deep stretch marks.
2. When Do Stretch Marks Typically Appear?
Many expectant mothers ask, "I'm 5 months pregnant, and my belly isn't that big yet. Will I get stretch marks?"
Stretch marks usually don't appear in early pregnancy. Most expectant mothers begin to notice their first stretch marks around the 6th or 7th month of pregnancy. However, there is no one-size-fits-all timeline, as it varies from person to person:
- Some mothers may start seeing them in the second trimester (13-27 weeks), a stage when the fetus's growth accelerates and the uterus expands rapidly, leading to increased stretching of the abdominal skin.
- Some lucky mothers may not see them until just a few weeks before delivery. These women often have good skin elasticity, well-controlled weight gain, or a favorable genetic predisposition.
- A very small number of women may not get stretch marks after pregnancy at all.
So, there's no need to worry too early, but don't become complacent either. Focusing on skin care from the second trimester onwards can be the best way to prevent stretch marks.
3. Can Stretch Marks Go Away?
"If I get stretch marks, can stretch marks go away after I give birth?" This is a core question for many mothers. First, it's important to be clear: it is very difficult to completely "remove" existing stretch marks and restore the skin to its original state. However, they can be significantly faded with proper care to make them less noticeable.
How to remove a stretch mark? Why can't they be completely removed? Because the essence of a stretch mark is a tear in the dermal elastic fibers. Once these fibers break, they are difficult to restore to their original, intact state (like a broken rubber band that can't regain its initial elasticity even if it's mended). Nevertheless, as hormone levels return to normal after childbirth, the color of the stretch marks will change—from the reddish-purple of pregnancy to a silver-white or flesh-tone. This reduces the color difference with the surrounding skin, making them visually much lighter than during pregnancy.
If you want to further fade stretch marks, you can choose appropriate postpartum care methods. For example, using body lotions or repair creams containing ingredients like asiaticoside, vitamin E, or hyaluronic acid can help promote skin metabolism and provide moisture and nutrients for firmer skin. Massaging can also improve local blood circulation and aid skin repair. For more noticeable stretch marks, medical aesthetic treatments such as laser therapy or microneedling can be considered under a doctor's guidance. These methods can stimulate collagen regeneration, making the lines shallower and smoother.
Remember: The key to postpartum care is to start early (generally recommended after lochia has stopped and there are no broken skin areas) and to be consistent. Skin repair is a slow process and often requires 3 to 6 months or more to show noticeable results, so don't expect a quick fix.
4. The Best Way to Prevent Stretch Marks: Follow These 5 Steps
Compared to fading stretch marks after they appear, prevention during pregnancy is far more important. By following a proper care routine, you can significantly reduce the chances of getting them or make the ones that do appear shallower and fewer. The following methods can help reduce the severity and incidence of stretch marks:
- Control Weight, Avoid Rapid Gain: If you gain more than 2 kg (4.4 lbs) each month, your abdominal skin will stretch quickly, and elastic fibers can easily break. Therefore, it is important to manage your weight gain throughout pregnancy based on your pre-pregnancy weight.
- Eat a Balanced Diet: Eat foods rich in protein, vitamin C, and vitamin E (such as eggs, milk, lean meat, fresh fruits, and vegetables) to help maintain skin elasticity.
- Stay Hydrated and Moisturize the Skin: Drink at least 8 glasses of water daily and apply a dedicated stretch mark cream or natural oil twice a day, especially on areas prone to stretch marks like the abdomen, breasts, hips, and thighs.
- Perform Gentle Massages: Massaging improves blood circulation and helps the skin absorb nutrients. After applying lotion, you can spend 5-10 minutes massaging the prone areas daily.
- Wear Comfortable Maternity Clothes: Wear loose-fitting, breathable, and elastic maternity clothes. Avoid tight clothing, as it can compress the skin, affect blood circulation, and increase the risk of stretch marks.
5. Is Pregnancy the Only Cause of Stretch Marks?
In fact, "stretch marks" are not exclusive to pregnant mothers!
- During rapid growth in puberty: Many teenagers develop similar lines on their thighs, hips, or lower back during growth spurts.
- During periods of significant weight change: Whether you gain weight too quickly or lose it too fast, your skin may not be able to adapt, leading to these lines.
- During muscle-building phases: Some fitness enthusiasts find that as their muscles grow quickly, similar lines appear on their skin.
- During periods of hormonal change: Certain hormonal medications or endocrine changes can also weaken elastic fibers, leading to the formation of lines.
Most importantly, whether it's a pregnancy stretch mark or another type of stretch mark, they do not affect your physical health. They also do not make you "unattractive." They are simply a natural mark of your body's growth and change.
Finally, a message to all mothers:
Stretch marks are a normal mark of pregnancy. They are a testament to your baby's growth inside you. Even if you get them, there's no need to feel anxious. With scientific postpartum care, the marks will gradually fade. The most important thing during pregnancy is to maintain a relaxed mindset and take good care of yourself and your baby. After all, your health and happiness are the best gifts for your little one.
No one has the right to define what "perfect" skin should look like, nor should they demand that every woman be flawless. These lines, like a tiger's unique stripes in nature, tell a story of change, courage, and the power of life. Why isn't that a form of cool beauty?
