Reviewed against :ACOG, AAD, and FDA guidance

A week after she tested positive, a reader emailed me with a photo of her bathroom counter and one question: “How much of this do I need to throw out?” She was in her eighth week, her skincare routine had thirteen products in it, and she’d spent the previous three days on Pinterest convinced that her tretinoin, her vitamin C, her AHA toner, her chemical sunscreen, and probably her moisturiser were all going to harm the baby.

She was wrong about most of it. And she’s the reason I’m writing this pregnancy safe skincare guide the way I’m writing it.

 Your Pinterest “Avoid List” Is Mostly Wrong

Here’s the part that makes people uncomfortable. The viral pregnancy-safe skincare checklists circulating on TikTok, Instagram, and Pinterest are mostly copied from other checklists that were copied from blog posts written in 2014. They over-flag ingredients that actual obstetric and dermatologic guidelines don’t flag, and they consistently under-flag ingredients that ACOG and the AAD genuinely warn about.

The list of topical ingredients with documented evidence of harm during pregnancy is narrow. It’s narrower than the clean beauty industry wants you to believe, because a restrictive list sells a lot of expensive “pregnancy-safe” reformulations. And it’s narrower than the internet wants you to believe, because fear is more shareable than nuance.

The actual guidance from the American College of Obstetricians and Gynecologists and the American Academy of Dermatology is specific. There are about six ingredient categories you genuinely need to stop using. Everything else — including some of the ingredients all over the “avoid” lists — is either fine, fine in moderation, or missing enough evidence that the conservative choice is individual rather than mandatory.

What I’m going to do in this article is walk you through what the evidence actually says, what it doesn’t say, and what the clean beauty industry is hoping you don’t ask.

The Six Ingredients That Are Actually Worth Avoiding

1. Topical retinoids (tretinoin, adapalene, tazarotene, retinol, retinaldehyde)

This one is real. Oral isotretinoin is a known teratogen — so well-documented that the iPLEDGE program exists specifically to prevent pregnancy during and after treatment. Topical tretinoin and its cousins have a much smaller body of evidence, but case reports of retinoid embryopathy after topical use exist, and both ACOG and the AAD recommend discontinuation during pregnancy and breastfeeding.

This includes cosmetic retinol and retinaldehyde, even at the 0.1% concentrations sold on Amazon. The FDA classifies topical tretinoin as Pregnancy Category C (or in the newer PLLR labelling, “risk cannot be ruled out”). The conservative answer is to stop all vitamin A derivatives the moment you know.

If you were on prescription tretinoin when you conceived — which is a specific demographic most pregnancy skincare articles skip entirely — don’t panic. Talk to your OB. The documented cases of retinoid embryopathy from topical exposure are rare enough that the typical guidance is to stop now, not to catastrophise about exposure that already happened.

2. High-dose salicylic acid (chemical peels and oral aspirin-level exposure)

This is the ingredient most over-flagged on Pinterest, and the reason the nuance matters. ACOG’s position is that low-dose topical salicylic acid — meaning the 0.5% to 2% concentrations in standard acne cleansers and spot treatments — is fine. The concern is with salicylic acid chemical peels performed at dermatology clinics, or oral doses equivalent to aspirin.

So if you were using a CeraVe SA cleanser or a Paula’s Choice 2% BHA, you can keep using them. If you had a 20% salicylic peel scheduled, cancel it. The internet treats both the same. The evidence doesn’t.

3. Hydroquinone

This is a skin-lightening ingredient prescribed for melasma and hyperpigmentation. It has the highest systemic absorption rate of any topical skincare ingredient — about 35 to 45% absorbs into the bloodstream. There’s no good data on pregnancy outcomes, which in the absence of evidence is enough for ACOG and most dermatologists to recommend avoiding it.

If you were using a prescription hydroquinone product for melasma, this is the one to stop immediately. The alternatives (azelaic acid, vitamin C, niacinamide) are genuinely pregnancy-safe and effective.

4. Oral isotretinoin (Accutane) and oral acne hormonal treatments

Not a topical, but worth naming because it’s the single most dangerous skincare-adjacent medication in pregnancy. If you’re on isotretinoin and might become pregnant, you’re almost certainly in the iPLEDGE program already. The same goes for oral spironolactone for hormonal acne — it’s classified as potentially teratogenic.

5. Certain essential oils (high-dose and specific compounds)

Here’s where “natural = safe” falls apart completely. Several essential oils are contraindicated in pregnancy because they can cross the placenta or trigger uterine contractions. The list includes pennyroyal, wintergreen, sage, rosemary in high concentrations, clary sage, juniper, and basil. These appear in plenty of “clean” aromatherapy skincare and massage oils marketed specifically at pregnant women.

A 2011 review in Canadian Family Physician by Bozzo and colleagues flagged this directly: the natural products category gets a safety pass it hasn’t earned, while conventional ingredients get over-scrutinised. I’ll come back to this.

6. Formaldehyde-releasing preservatives and high-dose benzoyl peroxide

These are on the conservative-caution list rather than the definitive-no list. Formaldehyde itself is an IARC Group 1 carcinogen and ACOG advises minimising exposure. Benzoyl peroxide at the 2.5 to 5% levels in OTC acne products is generally considered low-risk, but the AAD still recommends limiting to spot treatment rather than all-over use during pregnancy.

The Ingredients You’re Panicking About That Are Actually Fine

Chemical sunscreens

The viral claim that “all chemical sunscreens are unsafe in pregnancy” is not what the evidence says. The FDA’s 2019 proposed sunscreen monograph flagged oxybenzone and octinoxate as ingredients needing more safety data, and both have detectable absorption into the bloodstream. But ACOG’s position is that daily sun protection matters more than the theoretical risk from trace absorption — because melasma, which pregnancy dramatically increases the risk of, is far easier to prevent than to treat.

The reasonable middle ground: if it’s easy to switch to mineral sunscreen (zinc oxide and titanium dioxide), do. If you love your chemical SPF and it doesn’t contain oxybenzone, keeping it is not a crisis. Avobenzone, octocrylene, and Mexoryl have better safety profiles than oxybenzone. Check the ingredient list rather than rejecting the whole category.

Vitamin C (L-ascorbic acid and derivatives)

Completely safe during pregnancy. It doesn’t cross the placenta in any meaningful way topically, and it’s one of the best tools you have against the pregnancy mask — melasma — that’s about to become your main skin concern. A 10 to 20% L-ascorbic acid serum in the morning is exactly what most pregnant women with uneven tone should be using.

Niacinamide

Safe. Effective for the redness, sensitivity, and barrier disruption that pregnancy hormones cause for a lot of people. This is your retinol replacement for anti-aging work during these nine months.

Hyaluronic acid, ceramides, glycerin, squalane, panthenol

All safe. None of these cross the placenta in meaningful amounts. They’re the workhorses of a pregnancy-appropriate routine.

Glycolic acid and lactic acid at OTC concentrations

Generally safe at cosmetic concentrations (under 10%). The concern — like with salicylic acid — is with clinical-strength peels, not your drugstore AHA toner.

Azelaic acid

This is the MVP of pregnancy skincare and almost no one talks about it. It’s FDA Pregnancy Category B (the safest category short of “proven safe”), treats acne, treats melasma, calms rosacea, and brightens hyperpigmentation. If you have to pick one active to carry you through nine months, this is it.

Bakuchiol

The plant-based “retinol alternative” that gets uncritically marketed to pregnant women. The Dhaliwal and colleagues 2019 trial in the British Journal of Dermatology did show bakuchiol produced comparable wrinkle and pigmentation improvements to retinol over 12 weeks. But — and this matters — there isn’t yet robust pregnancy-specific safety data on bakuchiol. It’s widely considered safe because it doesn’t share retinol’s mechanism, but “widely considered” is different from “proven.” Most OBs I’ve seen quoted on this are comfortable with it. Just know that you’re making a reasonable-evidence choice rather than a proven-safe one.

What Most Articles Get Wrong

Misconception #1: “If it’s labelled pregnancy-safe, I can trust it.”

There is no FDA or EMA regulation of the term “pregnancy-safe” in cosmetics. It’s a marketing claim. Plenty of products carrying that label contain ingredients (certain essential oils, high concentrations of actives) that are not, in fact, well-studied for pregnancy. The “pregnancy-safe” line at Sephora may be charging you a 30% premium for the same basic moisturiser the brand sells in its general line, with prettier packaging and a mother-and-baby graphic.

Misconception #2: “Natural = safe.”

This is the single most dangerous assumption in clean beauty during pregnancy. Pennyroyal is natural. It’s also a known abortifacient. Multiple essential oils are more concerning in pregnancy than the parabens that brands have spent a decade training you to fear. The clean beauty industry has never had to reconcile this internally, and the pregnancy section is where it shows.

Misconception #3: “Better to just stop using everything for nine months.”

This is the failure mode I see most often, and the one that hurts the most. Women read the scariest list, get overwhelmed, and quit skincare entirely. Then pregnancy hormones trigger melasma, or their skin barrier collapses, or their hormonal acne erupts, and they end up six months in with worse skin than they started with and no idea how to fix it without violating the “avoid everything” rule they set for themselves. Doing nothing is not the safe option. Doing the right things is.

The Pregnancy-Safe Routine That Actually Works

Morning

1. Gentle cleanser: CeraVe Hydrating Facial Cleanser — ceramides, hyaluronic acid, no fragrance, works for every trimester.
2. Vitamin C serum: SkinCeuticals C E Ferulic if the budget allows, or Maelove Glow Maker if it doesn’t. L-ascorbic acid at 10 to 15%, daily, to prevent melasma before it starts.
3. Hyaluronic acid: The Ordinary Hyaluronic Acid 2% + B5. Apply to damp skin. Pregnancy skin gets thirsty.
4. Moisturiser: La Roche-Posay Toleriane Double Repair or Vanicream Moisturizing Cream. Both are fragrance-free, barrier-supporting, and genuinely pregnancy-safe rather than pregnancy-marketed.
5. Mineral SPF 30+: EltaMD UV Pure Broad-Spectrum SPF 47 or Blue Lizard Sensitive Mineral Sunscreen. Zinc oxide and titanium dioxide only. This is your melasma prevention, and it’s non-negotiable.

Evening

1. Same gentle cleanser. Or a second cleanse with an oil cleanser if you wore SPF and makeup.
2. Azelaic acid: The Ordinary Azelaic Acid Suspension 10% or prescription Finacea 15% if your OB or derm approves. This is your retinol replacement. It works for melasma, mild acne, redness, and overall tone.
3. Niacinamide (optional): Paula’s Choice 10% Niacinamide Booster. Buffer against the sensitivity pregnancy hormones tend to create.
4. Richer moisturiser or facial oil: Weleda Skin Food on dry nights. Squalane oil if you run oily.

For stretch marks (because you’ll ask)

Honest answer: the evidence that any topical product prevents stretch marks is weak. Genetics and rate of weight gain dominate. What topical products can do is keep the skin comfortable and reduce the itching that comes with rapid stretching. A fragrance-free body lotion with cocoa butter, shea butter, or ceramides applied consistently is as good as the $60 stretch mark creams. Palmer’s Cocoa Butter Formula is a perfectly reasonable pick.

Practical Tips Most Articles Skip

1. Start mineral SPF before the bump shows. Melasma is triggered by the combination of pregnancy hormones and UV exposure, and it often develops during the first trimester before women have even told people they’re pregnant. Don’t wait until month five.
2. Throw out retinol products rather than saving them for later. By the time you’re done breastfeeding, the formula will likely have oxidised and lost efficacy. Buy fresh when you’re ready to restart.
3. Read the full ingredient list on “natural” and “pregnancy-safe” labelled products. The marketing claims are unregulated; the ingredient list isn’t. Check for essential oils in the top half of the INCI list before you buy.
4. If you have dark skin and are worried about melasma, double down on vitamin C in the morning and azelaic acid at night. The melasma risk for Fitzpatrick IV through VI skin during pregnancy is significantly higher, and the post-pregnancy fade is slower. Most generic pregnancy skincare lists don’t mention this.
5. Don’t buy a whole new “pregnancy-safe” skincare line. You probably need to replace two or three products. Most of what you own is already fine. Paying $300 for reformulated non-actives with a mother-baby graphic on the bottle is exactly what the industry wants from you.
6. If you were on prescription tretinoin when you conceived, don’t doomscroll. Email your OB. The actual risk from topical tretinoin exposure during early pregnancy before you knew is genuinely low, but you need a real person to walk you through it rather than a Reddit thread.
7. Ask about azelaic acid before anything else. Your OB or derm is going to know about it, and it solves more pregnancy skin problems in one tube than any other single product.
8. For nausea-related sensitivity, cut fragrance entirely for the first trimester. First-trimester olfactory sensitivity is real, and fragrance in skincare is the most common trigger I hear about. This usually resolves in the second trimester.

Frequently Asked Questions

Is retinol safe during pregnancy if I only use it a few times a week?

No. The AAD and ACOG recommend discontinuing all topical retinoids during pregnancy and breastfeeding, regardless of frequency. The systemic absorption is low, but because oral retinoids are confirmed teratogens, the conservative guidance applies to the whole vitamin A derivative family.

Can I use salicylic acid cleanser during pregnancy?

Yes, at standard cosmetic concentrations (0.5 to 2%). ACOG’s concern is with salicylic acid chemical peels and oral aspirin-equivalent doses. Your CeraVe SA Cleanser or Paula’s Choice 2% BHA is fine. Leave-on products at 2% are generally considered safe, but spot-use rather than all-over application is the conservative approach for longer treatments.

Is bakuchiol a true retinol alternative during pregnancy?

It’s the best evidence-backed retinol alternative we currently have for pregnancy, but “best available” is not the same as “proven safe.” The 2019 Dhaliwal trial showed comparable results to retinol for wrinkles and pigmentation over 12 weeks. Pregnancy-specific safety data remains limited. Most dermatologists I follow are comfortable recommending it; a smaller number prefer azelaic acid because the evidence base is stronger.

What’s the best sunscreen for pregnancy?

A mineral sunscreen with zinc oxide, titanium dioxide, or both, at SPF 30 or higher. The reason isn’t that chemical sunscreens are confirmed unsafe — it’s that mineral formulations have zero systemic absorption concerns, and there’s no reason to choose the less-conservative option when an equally effective alternative exists. EltaMD UV Pure, Blue Lizard Sensitive, and CeraVe 100% Mineral Sunscreen are all appropriate picks.

Can I get melasma treated during pregnancy?

Not with hydroquinone or prescription tretinoin. You can absolutely work on prevention and mild treatment with vitamin C, azelaic acid, and diligent SPF. Aggressive melasma treatment (hydroquinone, tranexamic acid, cysteamine, lasers) waits until after you’ve finished breastfeeding. Prevention during pregnancy makes post-pregnancy treatment much easier.

Are essential oils safe in pregnancy skincare?

Some are, many aren’t, and the marketing doesn’t always tell you which. Lavender and chamomile at low concentrations are generally considered safe. Pennyroyal, wintergreen, clary sage, juniper, basil, and rosemary in high concentrations are contraindicated. If a “natural” pregnancy-safe product lists essential oils in its first five ingredients, check each one individually rather than trusting the label.

When can I go back to retinol after pregnancy?

Once you’re fully finished breastfeeding. The same restrictions that apply during pregnancy continue through lactation because topical retinoids can be excreted in breast milk. When you’re ready to restart, build back slowly — pregnancy and postpartum skin often has a temporarily compromised barrier, and jumping back to your pre-pregnancy retinol strength is a recipe for a rough few weeks.
