Pregnancy stretch marks: understanding, prevention, and treatment

Pregnancy marks a profound stage in a woman’s life, accompanied by numerous bodily transformations. As the belly rounds, the skin is heavily solicited and put to the test. This is why many pregnant women see stretch marks appear.

So, how can you prevent the appearance of stretch marks during pregnancy? Discover in this article all our tips for gently taking care of your skin throughout your pregnancy.

Stretch marks, definition:

A stretch mark is a skin mark that appears when the skin stretches too rapidly, causing a rupture of the collagen and elastin fibers. It manifests as streaks that are initially red or purplish, then white over time.

On black skin, a stretch mark is often purplish, dark red, or brownish-purple; it becomes lighter than the surrounding skin (beige, light gray, pearly white) over time.

Given that black skin is richer in melanin, the color of the stretch mark is generally darker at first, and this difference in pigmentation makes stretch marks more visible in the long term.

What are the causes of stretch marks during pregnancy?

On average, between 50% and 90% of pregnant women are affected by stretch marks during their pregnancy.

Stretch marks are common on the belly during pregnancy, but can also appear on the thighs, hips, or chest.

Stretch marks most often appear during the third trimester of pregnancy, when the skin is under significant tension. However, they can manifest as early as the second trimester in some women.

It is also important to note that stretch marks can occur after childbirth, a period during which mothers naturally give more attention to their baby, sometimes to the detriment of caring for their own skin.

Rapid stretching of the skin is the primary cause that explains the appearance of stretch marks. The growth of the belly, breasts, and sometimes hips leads to sudden tension on the skin. The collagen and elastin fibers weaken and then rupture, letting stretch marks appear. In this sense, significant weight gain during the pregnancy period also accentuates the stretching and increases the probability of stretch marks appearing.

Hormonal changes are also a factor explaining the appearance of stretch marks during pregnancy. Certain hormones (notably corticosteroids) decrease the production of collagen. The skin then becomes less resistant and thus more prone to internal tearing.

Genetic predisposition also plays an important role; if the mother, grandmother, or sister had stretch marks during their pregnancy, the mother-to-be is more likely to see stretch marks appear during her own pregnancy.

Finally, changes in blood circulation during pregnancy can impair the nutrition of the skin, making it more fragile and prone to stretch marks.

Regarding black skin, pregnant women encounter the same causes explaining the appearance of stretch marks (weight gain, hormones, genetics...). However, their appearance, progression, and visibility can differ in women with black skin. Thus, stretch marks can be more purplish, brown, or dark, eventually becoming lighter than the skin and sometimes more noticeable due to the pigment contrast.

Regardless of skin color, pregnancy stretch marks are multifactorial. They are common, natural, and in no way reflect a lack of care.

How to avoid stretch marks during pregnancy?

You are likely wondering how to prevent the appearance of stretch marks during pregnancy. While there is unfortunately no miracle solution, it is because stretch marks form in the deep layers of the skin, where topically applied skincare cannot act directly.

Furthermore, their appearance is influenced by factors over which it is difficult to have total control, such as hormonal variations and genetic predisposition.

Therefore, there is no miracle solution to completely prevent stretch marks, but a regular and adapted routine allows for significantly reducing their appearance and intensity.

The routine should be established from the beginning of pregnancy and consists of applying a rich skincare product morning and night to keep the skin supple and elastic.

1. Moisturize your skin every day throughout the pregnancy, favoring vegetable oils and butters naturally rich in essential fatty acids, such as date oil, sesame oil, sweet almond oil, shea butter, or mango butter.

2. Massage your skin regularly to stimulate microcirculation and improve skin elasticity, focusing on the belly, hips, breasts, and thighs. The massage can be done throughout the pregnancy using a cream or oil (such as sacred date oil). Five minutes of daily massage is enough; the important thing remains consistency.

3. Perform a weekly scrub to rid the epidermis of dead skin and impurities. Exfoliating optimizes the penetration of the moisture-rich active ingredients contained in the oils and creams that you will apply to your skin.

4. Drink enough water because skin that is well-hydrated from the inside will better resist stretching. It is important to drink between 1.5 to 2 liters per day, supplemented by a diet rich in fruits and vegetables.

5. Adopt, as best you can, progressive weight gain to avoid significant and rapid weight gain, which remains the primary cause explaining the appearance of stretch marks. To do this, avoid unnecessary calories by adopting a healthy, balanced diet and having medical follow-up that promotes healthy and progressive development.

Can you make stretch marks disappear after childbirth?

It is not possible to make stretch marks disappear completely after childbirth since they are a deep scar of the dermis, even though they may fade over time.

After pregnancy, stretch marks evolve naturally: they pass from a colored phase (red, purplish, or dark depending on the skin) to a lighter phase. This evolution generally makes them less visible, even if they remain present.

Thus, a regular routine can improve the appearance of the skin, and to do this:

1. Favor specifically formulated anti-stretch mark skincare, combining natural active ingredients, vitamins, and trace elements. These formulas help to attenuate the color of the stretch marks and improve their appearance.

2. Massage the affected areas to stimulate skin regeneration.

3. Avoid sun exposure, as with any scar, to prevent lasting pigmentation.

Note that there are adapted medical solutions that allow going further in their management, notably:

Microdermabrasion, which stimulates the renewal of the superficial layers of the skin
Laser treatments, which help to attenuate the appearance of scars.

Stretch marks are among the natural marks left by pregnancy. They are a testament to the body's transformations and deserve patience, gentleness, and kindness.
