Stretch Marks During Pregnancy: What to Expect and How to Prevent Them Naturally

You’re standing sideways in the mirror at 28 weeks, and there they are — faint pink lines fanning across your belly like tree branches. Your first thought is probably some version of did I do something wrong? You didn’t. And the honest truth about stretch marks during pregnancy is a lot more freeing than what the cream companies would like you to believe.

Let’s talk about what actually causes them, what genuinely helps, and what’s being sold to you.

What Stretch Marks Actually Are

The medical term is striae gravidarum — “gravidarum” simply means of pregnancy.

Your skin has two main layers that matter here. The dermis is the deeper layer, and it’s held together by collagen and elastin — proteins that give skin its strength and stretch.

When your skin expands faster than that support structure can adapt, the collagen and elastin fibers pull apart. What you see on the surface is the change underneath: thinner skin, with a slightly different texture, over the disrupted fibers.

So no — stretch marks aren’t your skin “tearing.” They’re a change in how the deeper layer is organized.

Two Stages

Striae rubra are the early ones: pink, red, or purple, sometimes slightly raised, occasionally itchy. The color comes from blood vessels visible through thinner skin.

Striae alba are the mature ones: pale, silvery, slightly sunken. This is where they land after months of fading.

The distinction matters, because early marks respond better to treatment than old ones. If you ever plan to address them, the window is sooner rather than later.

Why They Happen (It’s Not What You Think)

It’s Mostly Genetics

This is the finding that gets buried under product marketing. Family history is the single strongest predictor of whether you’ll get stretch marks in pregnancy.

If your mother and sisters got them, your odds are high — regardless of what you rub on your skin.

Hormones Play a Real Role

Pregnancy dramatically shifts your hormones. Some of these changes affect how your skin produces and maintains collagen and elastin, making the dermis more prone to disruption when it stretches.

This is why stretch marks aren’t purely mechanical. Two people can have identical bellies and completely different skin outcomes.

Other Contributing Factors

Research has associated stretch marks with younger maternal age, carrying multiples, larger babies, and greater or faster weight gain.

Here’s where I want to be careful with you. 💡 Please do not read that last item as “gain less weight.”

Appropriate pregnancy weight gain varies based on your starting point, and it’s a conversation for you and your provider — not something to manage for the sake of your skin. Restricting food during pregnancy carries real risks for you and your baby. Stretch marks are cosmetic. Nutrition is not.

Your body is building a person. Let it.

What Actually Works (An Honest Review)

Here’s where most articles hand you a list of miracle oils. I’d rather hand you the evidence.

What Has Been Tested and Failed

Cocoa butter. Studied in randomized trials. No meaningful benefit over placebo for preventing stretch marks.

Olive oil. Same story. Tested, no significant preventive effect demonstrated.

These are the two most recommended products on the internet. That should tell you something about how internet recommendations work.

What Has Weak, Inconclusive Support

Massage with oil or cream. Some studies hint at a small benefit — but here’s the interesting part: it may be the massage, not the product. Daily massage of the abdomen appeared in several of the more promising trials.

Centella asiatica preparations and hyaluronic acid have appeared in a few small studies with modest positive findings. The trials are low quality. ⚠️ And Centella asiatica should not be used in pregnancy without your provider’s approval.

What the Overall Evidence Says

Systematic reviews of stretch mark prevention have consistently reached the same underwhelming conclusion: there is not enough high-quality evidence to recommend any topical product for preventing stretch marks during pregnancy.

Not that they definitely don’t work. That we don’t have good evidence they do.

Is that disappointing? A little. Is it more useful than being sold a $60 belly balm? Absolutely.

⚠️ What to Avoid While Pregnant

This section matters more than the rest of the article.

Retinoids. Look for retinol, retinyl palmitate, tretinoin, adapalene, retinaldehyde. These vitamin A derivatives are common in skin products marketed for stretch marks and anti-aging. Topical and oral retinoids are not considered safe during pregnancy, and oral forms are strongly associated with birth defects. Read every label.

High-dose salicylic acid. Low-concentration products are generally considered acceptable, but stronger peels and treatments should be discussed with your provider.

Hydroquinone. Skin lightening agent, absorbed at higher rates than most topicals. Talk to your provider.

Essential oils, undiluted or unverified. Concentrated, and safety data in pregnancy is limited. Check with your OB or midwife first.

❌ When in doubt, take the product to your appointment and ask. Not to a forum. To your provider.

What Genuinely Helps (Even If It Won’t Prevent Them)

Approach	Prevents stretch marks?	Actually worth doing?
Daily gentle belly massage	Unproven, weak signal	✅ Yes — feels good, may help slightly
Fragrance-free moisturizer	No	✅ Yes — reduces itching and dryness
Staying hydrated	No evidence	✅ Yes — for every other reason
Balanced nutrition	No direct evidence	✅ Yes — for you and your baby
Cocoa butter	❌ Tested, no benefit	Harmless, low expectations
Restricting food intake	❌ No	❌ Never do this
Retinoid creams	Irrelevant	❌ Not safe in pregnancy
Accepting they may happen	N/A	✅ Genuinely the most useful thing here

Notice the pattern. The things that help are the things that make you more comfortable — not the things that promise to change your skin’s genetic destiny.

✅ Actionable Tips

1. Moisturize for comfort, not for prevention. Stretched skin gets dry and itchy. A plain, fragrance-free moisturizer helps with that. Frame it correctly and you won’t feel cheated later.

2. Massage gently, daily. Five minutes, circular motions, whatever oil or cream your provider approves. If it turns out to help a little, wonderful. If not, you spent five minutes a day connecting with your body.

3. Read every single label. Retinoids hide in “firming” and “anti-aging” formulas.

4. Eat well and gain as your provider advises. That’s the whole instruction. No skin-motivated restriction.

5. Manage the itch — but watch for a red flag. ⚠️ Intense itching, especially on your palms and soles, particularly at night, can signal a liver condition of pregnancy called cholestasis. This needs prompt medical attention. Don’t dismiss severe itching as “just stretching.”

6. If you want to treat them, wait and then act early-ish. After delivery, red-stage marks respond better to interventions than mature white ones. Talk to a dermatologist about options.

7. Stop looking at edited photographs. I mean this practically. The comparison is not real, and it’s costing you something.

After the Baby: Do They Go Away?

Not entirely. But they change a lot.

Over the months following delivery, the red and purple tones fade. What remains is usually pale, soft, and considerably less noticeable than what you saw in the mirror at 32 weeks.

For those who want to address them, dermatologists have real options — laser treatments, microneedling, radiofrequency, and prescription topicals. Results are typically improvement, not erasure, and outcomes vary by skin tone and mark age.

None of this is urgent. None of it is required. And postpartum stretch marks are not a problem to solve on a deadline.

Something Worth Saying Out Loud

Can I ask you something? Whose voice is it, when you look in the mirror and feel bad about those lines?

Because I’d bet it isn’t yours. It’s an industry that discovered a long time ago that a person who feels fine about her body doesn’t buy very much.

Most pregnant people get stretch marks. Most. That’s not a defect rate — that’s just what human skin does when it stretches to hold a human being. Your grandmother had them. So did hers.

You Didn’t Do Anything Wrong

Here’s what I want you to take from all of this: stretch marks during pregnancy are overwhelmingly determined by genetics and hormones, not by your discipline, your diet, or how much cocoa butter you remembered to apply at 11 p.m.

Moisturize because dry skin itches. Massage because it feels good. Eat well because you and your baby need it. Skip the retinoids, ask your provider about anything uncertain, and take severe itching seriously.

And then, if the lines come anyway — and for most of us, they do — let them be what they actually are. Not damage. Not failure. Just the record of something remarkable your body did.

You’re doing beautifully. The mirror isn’t the judge of that.
