Somewhere between the second and third trimester, most pregnant women notice thin, reddish-purple lines appearing across their belly, breasts, hips, or thighs. Stretch marks pregnancy stories are so common that they're practically a rite of passage — up to 90% of women experience them in some form. Yet the marketing around stretch mark creams often implies that with the "right" product, you can avoid them entirely. That's not quite true, and it's worth understanding why before you invest time or money chasing a promise skincare can't fully deliver. This guide covers what's actually happening under your skin, who's more likely to get stretch marks, and what genuinely helps — both for comfort now and for fading later.
What Causes Stretch Marks During Pregnancy
Stretch marks aren't just a cosmetic side effect of a growing belly — they're the result of two things happening beneath the skin's surface at once. Understanding both the mechanical and hormonal side helps explain why they show up for some women more than others.
The Physical Stretching
As your baby grows, your skin — particularly around the belly — stretches at a pace much faster than it would under normal circumstances. The middle layer of skin, the dermis, contains collagen and elastin fibres that give skin its stretch and snap-back ability. When skin expands quickly, these fibres can tear at a microscopic level. The result is a stretch mark: technically a form of scarring, not damage in the sense of something broken or unhealthy.
The Hormonal Factor
Rapid stretching alone doesn't fully explain causes of stretch marks during pregnancy — hormones play a significant supporting role. Pregnancy raises cortisol and other hormone levels, which can weaken the skin's elastic fibres and reduce its ability to stretch smoothly. This is part of why stretch marks can appear even in areas that aren't stretching dramatically, and why some women with relatively modest belly growth still develop them.
Who's More Likely to Get Them (and Why It's Not Your Fault)
Some women go through pregnancy with barely a mark, while others develop stretch marks even with minimal weight gain — and the difference usually has little to do with effort or skincare. A few key factors influence who's more likely to get them, and most are simply out of your control.
Genetics Plays the Biggest Role
If your mother or sisters had significant stretch marks during pregnancy, you're statistically more likely to as well. Skin elasticity and collagen structure are largely inherited traits, which means genetics often matters more than any skincare routine, no matter how diligent.
Other Contributing Factors
A few other factors influence likelihood: skin type (naturally drier or less elastic skin tends to show marks more readily), the rate and total amount of weight gain during pregnancy, carrying multiples (twins or more, due to faster and greater skin stretching), and younger maternal age, since skin elasticity naturally decreases with age but very young skin can also be more reactive to rapid change. None of these factors is within your control in the way skincare marketing implies — they're simply part of your individual biology, not a reflection of effort or self-care.

When Do Stretch Marks Typically Appear
Most women start noticing stretch marks in the second or third trimester, as the belly's growth rate accelerates. Common areas include the abdomen, breasts, hips, thighs, and lower back — anywhere skin is expanding to accommodate weight and shape changes. New stretch marks typically appear pink, red, or purplish, sometimes slightly raised and itchy. Over time — usually months, extending well past delivery — they gradually fade to a lighter, silvery-white tone and flatten out, though the timeline for fading varies significantly from person to person.
What Actually Helps: Prevention and Comfort During Pregnancy
While nothing can guarantee stretch marks won't appear, a few habits genuinely support your skin through the stretching process — easing itching, improving comfort, and keeping skin as healthy as possible. Here's what's actually worth doing, and why.
Consistent Moisturizing
While no cream can promise complete prevention, regularly moisturising your skin does genuinely help in a different way: it supports the skin barrier, reduces the itching and tightness that often come with rapid stretching, and keeps skin more comfortable throughout pregnancy. Think of moisturising as skin comfort care rather than a guaranteed prevention strategy.
Ingredients Worth Looking For
Some ingredients have modest evidence behind them for supporting skin elasticity and hydration — centella asiatica (often used in scar-focused skincare), hyaluronic acid for deep hydration, and rich butters like cocoa or shea for softening and soothing stretched skin. These won't stop stretch marks from forming if you're genetically predisposed, but they do make the stretching process more comfortable and support overall skin health.
Gradual, Steady Weight Gain
Where medically appropriate and in line with your doctor's guidance, gradual rather than rapid weight gain can ease the speed at which skin needs to stretch, which may reduce the severity of marks for some women — though this is one factor among several, not a guarantee.
Hydration and Nutrition
Staying well-hydrated and eating a diet that supports collagen production — foods with vitamin C, zinc, and protein — gives your skin the raw materials it needs to maintain elasticity, even if it can't override genetic predisposition entirely.
Gentle Massage While Applying Product
Massaging cream or oil into the skin, rather than just applying it, can improve circulation to the area and make the moisturising routine feel like a genuine self-care ritual during pregnancy, not just a preventive chore.
What Helps Stretch Marks Fade After Pregnancy
Most stretch marks look their most noticeable right after delivery and gradually soften over the following months. Here's what actually speeds up or supports that fading process, and what to hold off on until you're cleared by your doctor.
Time Is the Biggest Factor
For most women, postpartum stretch marks fading happens gradually and naturally over months, as marks shift from red or purple to a softer silvery-white and start to flatten. This process continues well after delivery and often surprises women with how much lighter marks become by the one-year mark, even without intervention.
Continued Moisturizing
Keeping up a consistent moisturising routine postpartum supports the skin's natural healing and can make the fading process more comfortable, even if it doesn't dramatically speed it up.
Retinoid Creams — Postpartum Only
Retinoid-based creams have real evidence behind them for improving the appearance of stretch marks by encouraging collagen production. However, retinoids are not considered safe during pregnancy or breastfeeding, so this option is only appropriate once you've stopped breastfeeding and have your doctor's clearance.
Dermatological Options
For women who want more visible fading beyond what time and topical products offer, options like microneedling or laser treatments exist and have supporting evidence for improving texture and colour. These are typically pursued well after delivery, in consultation with a dermatologist, and are a personal choice rather than a necessity.
Myths About Stretch Mark Creams and Prevention
It's worth addressing directly: no topical cream, oil, or butter can guarantee pregnancy stretch marks removal or complete prevention, regardless of how it's marketed. Stretch marks form based on collagen structure, hormone levels, and genetics — factors that exist well beneath the surface layer any cream can reach. This doesn't mean skincare is pointless during pregnancy; consistent moisturizing genuinely supports comfort, reduces itching, and keeps skin healthier through a period of rapid change. It simply means the goal should be comfort and skin support, not a guaranteed cosmetic outcome that isn't realistically within a product's control.
