Pregnancy acne arrives at the least convenient moment: the first trimester, alongside the nausea and the exhaustion, and often before you have told anyone why you look so tired. It is common, it is hormonal, and it is one of the few pregnancy symptoms where the wrong response is genuinely risky — not because acne is dangerous, but because the most effective acne drug in existence is also one of the most reliable causes of birth defects.
The short answer: breakouts in the first and third trimesters are normal and usually improve in the second. Azelaic acid, niacinamide and low-concentration benzoyl peroxide are the usual safe options. All retinoids stop — isotretinoin, tretinoin, adapalene and cosmetic retinol — and isotretinoin has to stop before conception, not at the first scan. Severe cystic acne is worth seeing someone about; there are treatments suitable in pregnancy and there is no reason to wait it out.
Why it happens
Androgen levels rise through pregnancy. Androgens drive the sebaceous glands, sebum production increases, follicles block, and the bacteria that live in them do the rest. That is the whole mechanism, and it explains the timing: the first trimester is when the hormonal shift is sharpest, and the third is when it climbs again after the mid-pregnancy plateau.
It also explains why the second trimester so often clears it. Nothing you did worked — the hormones settled. That is worth knowing before you spend the second trimester crediting a product that happened to be in your hand at the time.
What is normal
| Pattern | Normal | Worth an appointment |
|---|---|---|
| Type | Whiteheads, blackheads, small inflamed spots | Deep, painful nodules or cysts under the skin |
| Where | Face, sometimes chest and back | Widespread, or scarring as spots heal |
| Course | Worse in T1, better in T2, may return in T3 | Steadily worsening through the pregnancy |
| Effect | Annoying | Affecting how you feel about going out or being seen |
That last row is not a soft criterion. Acne has a well-documented effect on mood, and pregnancy is a period when mood is already under pressure. "It is only skin" is a reason to treat it, not a reason to endure it.
What is safe to use
✓ Generally considered safe
- Azelaic acid — the usual first choice in pregnancy. Works on both the blocked pore and the inflammation, and also helps the pigmentation acne leaves behind, which matters in a pregnancy that is already darkening your skin.
- Niacinamide — anti-inflammatory, well tolerated, and in most moisturisers already.
- Benzoyl peroxide — low concentration, over a limited area. Very little is absorbed and what is gets broken down quickly.
- Low-concentration glycolic or lactic acid — a mild exfoliant, not a peel.
- A gentle non-foaming cleanser twice a day. Stripping the skin drives more oil, not less.
Stop, and stop before conception if you can: isotretinoin (Roaccutane and equivalents) is a known teratogen — pregnancy must be avoided during treatment and for a period afterwards, which is the entire reason it is prescribed under a pregnancy prevention programme. Topical retinoids — tretinoin, adapalene, tazarotene, and retinol in cosmetics — are avoided too. Tetracycline antibiotics (doxycycline, lymecycline, minocycline) are avoided from the second trimester because they affect developing teeth and bone.
If you have used any of these without knowing you were pregnant: stop now, and tell your doctor or midwife so it can be discussed properly. Exposure is not the same as harm, and this is a conversation to have with someone rather than with a search engine at 2am.
When to call your midwife or doctor
Acne itself is not an emergency and never becomes one. Two things on this page are worth a call rather than a wait:
- Severe or cystic acne — deep painful lumps, or spots leaving scars. There are treatments suitable in pregnancy and getting them started early is what prevents the scarring.
- Retinoid exposure in pregnancy — not urgent, but not something to sit on either. Ring during working hours and say what you took and when.
One thing that is genuinely urgent and is sometimes mistaken for a skin problem: a widespread itchy rash, or intense itching with no rash at all, particularly on the palms and soles. That is not acne and it is covered under itching and stretch marks — it needs a same-day call.
Acne in pregnancy — at a glance
Rising androgens increase sebum, which is why acne flares hardest in the first trimester, frequently clears in the second, and often returns in the third. Azelaic acid, niacinamide, low-concentration benzoyl peroxide and mild glycolic or lactic acid are the usual safe options, alongside gentle twice-daily cleansing — stripping the skin makes oil production worse. All retinoids stop: isotretinoin before conception under its pregnancy prevention programme, and topical tretinoin, adapalene and cosmetic retinol as soon as you know. Tetracycline antibiotics are avoided from the second trimester. Severe cystic acne is not something to endure until birth; there are prescribing options in pregnancy and starting them early is what prevents scars. Most pregnancy acne settles over the months after delivery, though the retinoid restrictions continue while breastfeeding.

Frequently Asked Questions
Why does acne get worse in pregnancy?
Androgen levels rise in pregnancy, and androgens increase sebum production. More sebum means more blocked follicles. The effect is strongest in the first trimester, when the hormonal change is steepest, and often again in the third. Many people find the second trimester clears it — the same hormonal settling that eases nausea.
Which acne treatments are safe in pregnancy?
Gentle cleansing plus azelaic acid, niacinamide, and benzoyl peroxide in low concentration over a limited area are the usual first choices. Low-concentration glycolic or lactic acid is generally accepted. If topicals are not enough, there are oral antibiotics considered suitable in pregnancy — that is a prescribing decision, so ask rather than buy.
Do I have to stop retinoids when I find out I am pregnant?
You have to stop before that. Isotretinoin is a known teratogen and pregnancy must be avoided during treatment and for a period after stopping, which is why prescribing comes with a pregnancy prevention programme. Topical retinoids — tretinoin, adapalene, retinol in cosmetics — are also avoided. If you have used one without knowing you were pregnant, stop and tell your doctor; do not assume the worst on your own.
Is salicylic acid safe in pregnancy?
A face wash containing a low concentration, used briefly and rinsed off, is generally treated as acceptable. What is avoided is high-concentration salicylic acid — peels, and leave-on products at strength — because more of it is absorbed. If a product is a wash rather than a serum, that is usually the safer form of the same ingredient.
Will pregnancy acne go away after birth?
Usually, though not immediately. Skin generally settles over the months after birth as hormones return to baseline, and breastfeeding can extend that. If it has not cleared and it bothers you, it becomes an ordinary dermatology question again — but the retinoid restrictions still apply while breastfeeding, so it is worth saying you are feeding when you ask.
