Pregnancy-Safe Acne Treatment: What’s Safer and What to Avoid

Acne during pregnancy can usually be treated, but the list of options shrinks. Azelaic acid, benzoyl peroxide and topical clindamycin or erythromycin are the treatments most often described as safer choices, while isotretinoin, topical retinoids, oral tetracyclines such as doxycycline, and spironolactone are generally avoided. Because advice depends on your trimester, your acne and your health history, every choice here is one to make with your OB or dermatologist.

A quick note on how to read this page: I’m a researcher, not a clinician. “Safer” below means that guidelines and expert sources consider the risk low based on limited data, not that anything has been proven risk-free. Pregnant people are rarely included in drug trials, so much of this guidance leans on animal studies, absorption data and observational studies.

Why does acne change during pregnancy?

Hormones are the likely driver. Mayo Clinic explains that pregnancy acne is probably caused by excess oil (sebum) production when the body makes more of certain hormones. Some people break out for the first time, and others notice their usual acne gets better or worse. A 2024 review in the American Journal of Clinical Dermatology points out that acne is one of the most common skin conditions in women of childbearing age, which is exactly why so many people end up needing to rethink their routine when they get pregnant.

Which acne treatments are generally considered safer in pregnancy?

The same handful of ingredients shows up across the American Academy of Dermatology (AAD), MotherToBaby, NICE and the review literature:

Azelaic acid

The AAD notes that animal studies of azelaic acid have not shown birth defects. A 2016 review in the Journal of the American Board of Family Medicine (Chien et al.) lists azelaic acid as a safe baseline option and reports that only about 4% is absorbed through the skin. I cover how it’s used for acne in azelaic acid for acne.

Benzoyl peroxide

The AAD says experts consider benzoyl peroxide safe “in limited amounts,” and suggests checking with your provider first. The Chien review explains that it is metabolized to benzoic acid and cleared quickly by the kidneys. MotherToBaby notes that the American College of Obstetricians and Gynecologists (ACOG) has suggested benzoyl peroxide, azelaic acid, salicylic acid or glycolic acid for use in pregnancy if needed.

Topical antibiotics (clindamycin, erythromycin)

According to the AAD, “applying clindamycin during pregnancy is thought to be safe,” though it again recommends checking with your obstetrician or dermatologist first. Mayo Clinic also lists topical erythromycin and clindamycin as generally considered safe. The Chien review recommends pairing a topical antibiotic with benzoyl peroxide, which is standard practice to limit antibiotic resistance. The UK’s NICE guideline says a fixed combination of benzoyl peroxide with clindamycin “can be used with caution during pregnancy and breastfeeding.”

Salicylic acid (with limits)

The AAD describes salicylic acid as generally considered safe “when used for a limited time,” and the Chien review puts the risk as low if use is restricted to local areas for a limited duration. The 2024 AAD guideline likewise advises limiting salicylic acid to small areas during pregnancy. In practice, that points toward a wash or spot treatment rather than covering large areas with leave-on products.

Which acne treatments should you avoid while pregnant?

A few of these deserve more context. Isotretinoin is in a category of its own: the risk of serious harm to a developing baby is well established, and the AAD says it must be stopped immediately if you become pregnant, so contact your prescriber right away. The tetracycline warning is about timing and development: the label also notes possible reversible slowing of bone growth when used in the second and third trimesters. With spironolactone, the concern comes from how the drug works (it blocks androgens) and from animal studies showing feminization of male offspring. For hormonal-acne readers who rely on spironolactone, this usually means planning a transition with your prescriber before trying to conceive; see spironolactone for acne.

I used tretinoin or adapalene before I knew I was pregnant. Should I worry?

Tell your OB, but the evidence is reassuring. MotherToBaby explains that only a small amount of topical tretinoin is absorbed through the skin, that topical use is not expected to increase the chance of miscarriage, and that studies of people who used it as directed have not found an increased risk of birth defects. There are scattered case reports of birth defects, which is why the cautious advice is to stop once you know you’re pregnant. The 2025 label for tretinoin microsphere gel says published studies over decades “have not established a drug-associated risk” of major birth defects or miscarriage. I go deeper on this in tretinoin for acne.

This reassurance does not extend to oral isotretinoin, which is a different situation entirely.

What if you need more than creams?

For more severe, inflamed acne during pregnancy, there are options, but they belong firmly in the hands of your care team. The AAD mentions that some oral antibiotics (such as azithromycin) appear to be safer, though documentation is limited, and that laser and light therapies are considered relatively safe but need a dermatologist’s input. The 2024 review covers oral options that are typically second-line for acne, including antibiotics such as cephalexin, amoxicillin, azithromycin and erythromycin, and corticosteroids. These are prescriber decisions based on your situation, not things to arrange on your own.

What about breastfeeding?

The LactMed database (NIH) is the best single resource I found. Its entries say:

• Benzoyl peroxide: about 5% is absorbed through the skin, so it’s considered low risk to the nursing infant. Make sure the baby’s skin doesn’t touch treated areas.
• Azelaic acid: about 4% is absorbed, and it occurs naturally in foods and breast milk, so it’s considered low risk.
• Topical clindamycin: infant side effects are unlikely with use for acne, but applying it to the breast may increase the risk of diarrhea if the baby ingests it.
• Topical tretinoin: poorly absorbed and considered low risk, though it hasn’t been studied in breastfeeding.
• Isotretinoin: no information is available, and topical agents that are less likely to be absorbed may be preferred, especially with a newborn or preterm baby.

Two others worth knowing: the doxycycline label says breastfeeding is not recommended during treatment and for 5 days afterward, and the spironolactone label reports low amounts of an active metabolite in breast milk and asks clinicians to weigh benefits and risks. For anything applied on or near the breast, LactMed recommends water-based creams or gels over ointments.

A gentle, lower-risk routine to discuss with your OB

1. Wash twice a day with a gentle cleanser, using your hands rather than scrubbing, as Mayo Clinic suggests.
2. Choose non-comedogenic or water-based products for moisturizer and makeup (Mayo Clinic).
3. Pick one treatment from the safer list, such as azelaic acid or a benzoyl peroxide wash, after checking with your provider.
4. Resist picking and popping, as the AAD advises for acne in general.
5. Give it time. Most acne treatments need weeks to months to show results; see how long acne treatments take.
