Acne During Pregnancy: Causes and Safe Treatments

Acne during pregnancy happens because rising hormone levels — especially androgens and progesterone — trigger the skin to produce more oil, which clogs pores. It's most common in the first trimester, and while several prescription acne medications aren't safe to use while pregnant, a number of over-the-counter ingredients are.

Why Does Pregnancy Cause Acne?

Acne forms when hair follicles get blocked by a mix of sebum (the skin's natural oil), dead skin cells, and bacteria. Pregnancy sets up ideal conditions for this.

>In the first trimester, androgen levels — a group of hormones that includes testosterone — rise considerably, and androgens stimulate the sebaceous glands to produce more sebum.Progesterone also rises during pregnancy and can increase oil production, raise body temperature, and worsen sweating— both of which contribute to clogged pores.

Estrogen, which also rises during pregnancy, typically has a beneficial effect on skin clarity, which is why some people find their skin improves in the second trimester as estrogen levels stabilize alongside the initial androgen surge. Skin response varies significantly from person to person, and even from one pregnancy to the next.

How Common Is Pregnancy Acne?

More than half of pregnant people can expect to develop acne, and in some cases it can be severe.The main driver is increased hormone levels in the first trimester, which boost the skin's production of natural oils.It's hard to predict who will develop pregnancy acne, though the risk is higher for those with a history of acne or acne flares at the start of their menstrual cycle. If breakouts don't appear during the first trimester, it's unlikely that unusual breakouts will show up in the second or third trimesters.

Where Pregnancy Acne Typically Shows Up

Pimples are likely to show up on the face, neck, chest, or back — and during pregnancy, deeper nodular acne is common rather than just small whiteheads. These are red, painful bumps that sit under the skin, and the inflammation can leave dark spots or scarring behind, though some treatments can help prevent that damage. Acne Treatments to Avoid During Pregnancy

This is the part that matters most: several common acne medications are linked to birth defects and should not be used during pregnancy.

According to ACOG (the American College of Obstetricians and Gynecologists), treatments to avoid include:

Isotretinoin —This vitamin A derivative may cause severe birth defects, including intellectual disabilities and life-threatening heart and brain defects.Because the risks are so high, women of childbearing age who take it need to use two forms of birth control starting at least a month before treatment and continuing for at least a month after, along with pregnancy testing before, during, and after treatment.
Hormonal therapy —Medications that block specific hormones, such as certain anti-androgens, are not recommended during pregnancy due to the risk of birth defects.
Oral tetracyclines (including doxycycline, minocycline, and tetracycline) — These antibiotics can discolor a baby's teeth if taken after the fourth month of pregnancy and can affect fetal bone growth for as long as the medication is used.
Topical retinoids (such as adapalene, tazarotene, and tretinoin) These are in the same drug family as isotretinoin. Although the amount absorbed through the skin is low, it's generally recommended to avoid them during pregnancy.

Acne Ingredients Generally Considered Safe During Pregnancy

ACOG notes that ingredients such as azelaic acid, glycolic acid, benzoyl peroxide, and topical salicylic acid are commonly considered safe during pregnancy when recommended by a healthcare provider.

A gentle approach is usually the right starting point:

Start with a mild cleanser. A scent- and dye-free cleanser used twice a day for one to two weeks is typically the first line of defense.
Add an over-the-counter option if needed. If the cleanser alone doesn't help, an over-the-counter medication may be the next step.
Talk to a provider before adding anything stronger. If you're concerned about which products to use, a conversation with your dermatologist and OB-GYN together can help you decide which option fits your situation.

When Does Pregnancy Acne Go Away?

For most people, pregnancy acne fades within a few weeks to a few months after giving birth, once hormone levels settle back down. That said, postpartum acne — driven by its own hormonal shifts — is common too, so clearer skin isn't always immediate.

A Quick Note on the "Pregnancy Acne Predicts Baby's Sex" Myth

There's no scientific evidence that pregnancy acne predicts a baby's sex. Acne is influenced by hormones, not by the baby's gender. It's a widely repeated old wives' tale, not a diagnostic sign.

FAQ

Is acne a sign of early pregnancy?
Acne can be an early sign of pregnancy, since hormonal surges — especially rising progesterone — increase oil production and can trigger breakouts. But it's not a reliable indicator on its own
, so it shouldn't replace a pregnancy test.

When during pregnancy does acne usually start?
Pregnancy acne most commonly appears during the first trimester, often between weeks 6 and 10, when hormonal fluctuations are at their most dramatic — though breakouts can occur at any stage, including flares in the third trimester as progesterone peaks.

Can I use benzoyl peroxide while pregnant?
Benzoyl peroxide is one of several topical ingredients ACOG considers generally safe during pregnancy when a healthcare provider recommends it, alongside azelaic acid, glycolic acid, and topical salicylic acid. Still, check with your OB-GYN before starting any new product.

Is it safe to use my old prescription acne medication while pregnant?
Not necessarily. Isotretinoin, hormonal acne therapies, oral tetracycline antibiotics, and topical retinoids are all generally advised against during pregnancy due to birth defect risks. Talk to your provider before continuing or restarting any prescription treatment.

Will pregnancy acne go away on its own?
For most people, yes — acne typically clears up within a few weeks to months after delivery as hormone levels return to their pre-pregnancy state. Postpartum acne can still occur, though, so some breakouts may continue for a while.

Takeaway

Pregnancy acne is common, hormone-driven, and usually temporary. Start gentle — a mild, fragrance-free cleanser is often enough — and if you need more, stick to ingredients like azelaic acid, glycolic acid, benzoyl peroxide, or topical salicylic acid, ideally with sign-off from your OB-GYN or dermatologist. Steer clear of isotretinoin, oral tetracyclines, hormonal acne therapies, and topical retinoids until after pregnancy.
