Stretch Marks During Pregnancy - Prevention and Treatment

Your belly is growing, and maybe you've noticed pink or purple lines on your skin. Stretch marks during pregnancy are very common and affect between 50 and 90 percent of all pregnant women. They are completely harmless, but many wonder whether they can be prevented and what helps.

What Are Stretch Marks?

Stretch marks (striae gravidarum) are small tears in the deeper layers of the skin — the dermis. They occur when the skin is stretched rapidly and collagen fibers break down faster than they are rebuilt.

Initially they are pink, red, or purple. Over time they fade and become lighter than the surrounding skin — often white or silver. This process takes months to years.

The most common places for stretch marks during pregnancy:

• The belly — especially around the navel and lower abdomen
• The hips
• The breasts
• The thighs
• The upper arms

Why Do Some People Get Stretch Marks and Others Don't?

Your genes play a major role. If your mother got stretch marks during pregnancy, the chances are higher that you will too.

Factors that increase the risk:

• Hereditary predisposition — the single most important factor
• Rapid growth — significant weight gain or a quickly growing belly
• Younger age — younger skin stretches more
• Large baby or excess amniotic fluid — the belly becomes especially large
• Twins or multiple pregnancies
• Skin type — lighter skin may be more prone, but all skin types can get stretch marks

When Do Stretch Marks Appear?

Most stretch marks appear in the third trimester, from around week 28 onwards, when the belly is growing fastest. But some may notice them as early as the second trimester, especially on the breasts which often grow early in pregnancy.

Prevention — What Can Help?

No method has been scientifically proven to completely prevent stretch marks, but good skincare can help keep the skin supple.

Moisturize Regularly

• Apply moisturizer or oil to your belly, hips, and breasts daily
• Start early in pregnancy, before the belly begins to grow rapidly
• Choose products without fragrance and harsh additives

Moderate Weight Gain

WHO and major health authorities recommend a weight gain of:

• 25–35 lbs (11.5–16 kg) with a normal BMI (18.5–24.9)
• 15–25 lbs (7–11.5 kg) with overweight (BMI 25–29.9)
• 11–20 lbs (5–9 kg) with obesity (BMI over 30)

Gradual weight gain gives the skin time to stretch slowly.

Stay Hydrated

Drink plenty of water. Well-hydrated skin is more elastic and handles stretching better.

Eat a Varied Diet

A diet rich in vitamin C, vitamin E, and zinc can support the skin's collagen production. Fruits, vegetables, nuts, and whole grains are good sources.

Products — What Works?

The market is full of expensive creams that promise to remove stretch marks. Here's what the research says:

May help with prevention:

• Cocoa butter and shea butter — keeps skin moist and supple
• Almond oil — one study showed some benefit with daily use combined with massage
• Hyaluronic acid cream — helps retain moisture in the skin

Limited evidence:

• Vitamin E oil alone has not shown reliable prevention in studies
• Products claiming to "remove" stretch marks overpromise — no cream can fully repair breaks in the dermis

After birth:

• Retinol cream can stimulate collagen production and make new (red) stretch marks less visible. Retinol should not be used during pregnancy or breastfeeding.
• Laser treatment can improve the appearance of stretch marks, but does not remove them entirely. Discuss with a dermatologist.

Stretch Marks and Your Body

It's easy to feel frustrated about stretch marks, but try to have a realistic relationship with them. Your body is doing an incredible job creating new life.

The vast majority of stretch marks fade considerably over time. After one to two years they are often barely visible as faint lines. Many find they care less about them as time goes on.

Itching and Stretch Marks

When the skin stretches, it can itch. Mild itching over the belly is normal and can be relieved with moisturizer.

But intense itching, especially on the hands and feet, can be a sign of intrahepatic cholestasis of pregnancy (ICP) — a liver condition that requires medical attention.

After Birth

Stretch marks continue to change after birth:

• The first months — the colors may still be noticeable but begin to fade
• 6–12 months — most stretch marks have started to lighten
• 1–2 years — they have typically faded to silver-white lines

Pelvic floor exercises and general exercise after birth cannot remove stretch marks, but will strengthen your body.

Frequently Asked Questions

Can I avoid stretch marks completely?

Unfortunately there is no guarantee. Your genes are the biggest factor. Good skincare and moderate weight gain can reduce the risk, but cannot eliminate it entirely.

Do stretch marks disappear after pregnancy?

They don't disappear completely, but they fade considerably. Most people find that stretch marks go from clearly visible pink/purple to almost invisible silver-white lines over the course of one to two years.

Should I use special cream for pregnant women?

You don't have to. Regular moisturizer, almond oil, or coconut oil works just as well as expensive specialty products. What matters most is that you moisturize regularly and keep your skin hydrated.
