Pregnancy Glow, Science Approved: Glycolic Acid’s Gentle Touch

Pregnancy is an exciting time, but let’s be honest—it can also be downright confusing, especially when it comes to skincare. Suddenly, your trusty products might seem suspicious, and ingredient lists look more like science experiments. Even seasoned beauty lovers can find themselves second-guessing what’s safe and what’s not. But before you toss your skincare stash in a panic, there’s some good news: it’s not as complicated as it seems.
Topical acids, like glycolic acid, are skincare superheroes, tackling issues like acne, aging, and hyperpigmentation. But the stakes are higher during pregnancy—your skin absorbs ingredients, and some can make their way into your bloodstream (and potentially to your baby). So, what’s the deal with glycolic acid? Is it safe or off-limits for moms-to-be? Don’t worry—we’ve got you covered with the facts to help you glow safely through your pregnancy journey.
Glow, Grow, and a Few Bumps Along the Way: Your Skin During Pregnancy
Pregnancy is an exciting time full of changes; your skin is no exception. Hormones like estrogen, progesterone, and hCG (human chorionic gonadotropin) work overtime, influencing everything from your mood to your complexion. These hormonal shifts and physical changes can lead to some surprising skin developments—some you’ll love and others you might not be so thrilled about.
First up, the famous pregnancy glow. That radiant complexion isn’t just a myth! Increased blood flow and heightened oil gland activity give your skin a brighter, dewy appearance. It’s like a natural Instagram filter, courtesy of your body’s hard work. But there’s a flip side—those same hormonal changes that give you a glow can also lead to breakouts. If you’re suddenly battling acne during pregnancy (even if your skin was clear before), you’re not alone. Hormonal surges can boost oil production and clog pores, especially in the first trimester.
Then, there are pigmentation changes that are common and unique to pregnancy. Many pregnant people notice a dark line running down their belly, called the linea nigra, or dark patches on their face known as melasma (or the “mask of pregnancy”). These pigmentation changes happen because your body produces more melanin, the pigment responsible for skin color. While melasma can fade after pregnancy, sun exposure can make it worse, so SPF is your best friend!
Stretch marks are another big player in pregnancy skin changes, affecting up to 90 percent of pregnant people. These pink, purple, or silvery streaks often appear on the belly, thighs, chest, or hips as the skin stretches rapidly to accommodate your growing baby. Stretch marks happen when the middle layer of the skin, called the dermis, is pulled too quickly, causing collagen and elastin to tear. While they’re harmless, they can affect how you feel about your changing body—and that’s okay.
Acid With Benefits: Understanding Glycolic Acid

Glycolic acid is a naturally occurring compound found in fruits, sugarcane, and even beets. In its pure form, it’s clear, odorless, and a superstar in the skincare world. Cosmetic and pharmaceutical brands love it for its ability to tackle skin concerns and enhance skin texture—but don’t be fooled by its natural roots. Most of the glycolic acid in your favorite products is lab-made.
This powerhouse ingredient belongs to the alpha hydroxy acid (AHA) family, a group of exfoliating acids that are super popular in skincare. Other AHAs include citric acid (from citrus fruits), malic acid (from apples), and lactic acid (from milk). What makes glycolic acid stand out? Its tiny molecular size lets it dive deeper into your skin for maximum impact.
Glycolic acid comes with a list of impressive skincare perks that make it a go-to ingredient:
- Exfoliation Pro: Unlike rough scrubs or brushes, glycolic acid works as a gentle chemical exfoliant. It dissolves dead skin cells and excess oil on the surface, revealing smoother, fresher skin—no scrubbing required!
- Moisture Magnet: It’s also a humectant that pulls water into your skin and keeps it hydrated. This is thanks to its ability to boost glycosaminoglycans, which are like little sponges for your skin.
- Bacteria Buster: Some research suggests that glycolic acid, at specific concentrations, can help curb the growth of bacteria, making it a potential ally in keeping your skin clear.
- Age-Defying Hero: Glycolic acid tackles visible signs of aging by boosting collagen and hyaluronic acid production while reducing sun damage. The result? Skin that’s bouncier, firmer, and more youthful-looking.
While being a popular skincare ingredient, glycolic acid still comes with some risks. One big concern is sun sensitivity. While it can reduce signs of sun damage, it also removes the top layer of skin, making the fresh skin underneath more vulnerable to UV damage. That’s why daily sunscreen is non-negotiable—whether you’re using glycolic acid or have just stopped. Oh, and steer clear of tanning beds while you’re at it!
Some people might experience skin irritation, like redness, itching, swelling, or even a burning sensation. Pro tip: burning doesn’t mean “it’s working.” If your skin reacts badly, rinse it off and give it a break. Overusing glycolic acid, picking a formula that’s too strong, or applying it near sensitive areas like your eyes can make things worse. And if you accidentally get it in your eyes, flush with water immediately!
Finally, there’s hyperpigmentation—a bit of a double-edged sword. Glycolic acid can help fade dark spots, but if it’s too harsh or irritating, it might cause more pigmentation issues, especially for those prone to them. The solution? Stick to gentle formulas and go easy with your exfoliation routine.
Is Glycolic Acid Safe During Pregnancy?

Wondering if glycolic acid gets the green light while you’re expecting? The good news is that it’s generally considered safe—but there are a few things you need to keep in mind.
It’s worth noting that research on glycolic acid and pregnancy is limited, mainly because testing products on pregnant people is ethically tricky. Most of the information we have comes from observational studies or animal research. High doses of glycolic acid have shown some adverse effects when administered orally, but the concentrations typically found in skincare products are far lower and considered safe for humans. In fact, glycolic acid is often a safer alternative to other skincare ingredients, like retinoids, which are best avoided during pregnancy.
Many trusted experts, including the American College of Obstetricians and Gynecologists, list glycolic acid as a safe option during pregnancy, along with ingredients like salicylic acid, benzoyl peroxide, and azelaic acid.
Using glycolic acid while pregnant? Take it slow and steady. First, check the label—make sure the concentration is 10% or less, and double-check the other ingredients for safety. Pregnancy can make your skin extra sensitive, so even products you’ve sworn by in the past might surprise you now. Not sure what’s safe? Your doctor is your best go-to for advice!
Since glycolic acid can make your skin more sensitive to sunlight, it’s best to save it for your evening routine. Most formulas are either watery, like a toner, or slightly thicker, like a serum. After cleansing, apply a small amount to your skin. If you’re new to acids or have sensitive skin, start slow—two or three times a week is plenty. Overdoing it can lead to over-exfoliation, which may damage your skin barrier. And don’t forget the follow-up! Finish with a pregnancy-safe moisturizer or oil to keep your skin hydrated and happy.
Before diving in, do a quick patch test on a small skin area to check for reactions. This simple step can save you from irritation or surprises later on. Remember, skincare during pregnancy is about balancing safety and effectiveness. While glycolic acid can help you maintain that pregnancy glow, it’s always a good idea to keep your skincare routine gentle and uncomplicated.
Conclusion
Caring for your skin during pregnancy is all about smart, safe choices. Steer clear of potentially harmful ingredients like retinoids, and opt for products labeled safe for pregnancy. Skip the fancy fragrances, too—they’re often unnecessary and can irritate sensitive skin. It’s always a good idea to chat with your doctor before making significant changes to your routine. After all, what works for one person might not be the best for you or your baby.
When it comes to glycolic acid, the American College of Obstetricians and Gynecologists gives it the thumbs up—as long as it’s in lower concentrations. There are plenty of safe, effective options out there to help you keep your glow while tackling pregnancy skin concerns.
Staying informed and choosing products tailored to your skin type and needs will help you confidently nurture your skin during this special time. You’ve got enough on your plate growing a tiny human—your skincare should make things easier, not harder.
