Pregnancy safe sunscreen: how to read the filters

How do you find the filters on a sunscreen label?

Sunscreen filters are the active ingredients on the label. The AAD, the American dermatologists’ academy, sorts every sunscreen by them into three kinds.

If the only active ingredients are titanium dioxide, zinc oxide, or both, the academy says you have a physical sunscreen. People often call these mineral sunscreens. If neither is there, it is a chemical sunscreen. A hybrid mixes filters from both kinds.

The FDA lists 16 active ingredients for US sunscreens. The two minerals are zinc oxide and titanium dioxide. Other chemical filters on the FDA list include avobenzone, homosalate, octocrylene and three more with two names each.

Oxybenzone is also called benzophenone-3. Octinoxate is also called ethylhexyl methoxycinnamate. Octisalate is also called ethylhexyl salicylate. Find each name from your label in the list below.

Whatever the filters, the academy’s advice for everyone is the same: broad spectrum, SPF 30 or higher, and water resistant. Broad spectrum means it protects against both UVA and UVB rays.

What has the FDA said about mineral and chemical filters?

The FDA has proposed that only zinc oxide and titanium dioxide are safe and effective in sunscreen. For twelve other filters it asked for more data, which is not the same as finding harm.

The term it uses is GRASE, short for generally recognised as safe and effective. Its first proposal put the two minerals in that group up to 25 percent. A later proposed order kept that split. Its fact sheet lists oxybenzone, avobenzone, octinoxate and the rest as additional data needed. Neither step is a final order.

The data question is about absorption. The FDA says some active ingredients pass through the skin into the body, so it asked industry for safety data. It still says Americans should use sunscreen, along with other ways to protect themselves from the sun.

Europe has its own limit for one of them. The EU’s cosmetics safety committee (the SCCS) says homosalate is safe up to 7.34 percent in face cream and pump spray, given concerns about possible effects on hormones. That limit is not about pregnancy.

Should you avoid chemical sunscreen filters in pregnancy?

Pregnancy sources disagree about chemical filters. None of them says to go without sunscreen.

ACOG, the American College of Obstetricians and Gynecologists, has a page on chemicals before and during pregnancy. It says to read the ingredients on beauty and personal care products. When possible, it says, avoid products that contain oxybenzone, along with phthalates, parabens and triclosan. That is advice, and the page never mentions sunscreen.

A MotherToBaby blog post says some filters are absorbed, in small amounts. Many have not been studied very well in pregnancy, it says, but they are not known to harm the pregnancy or baby. Mineral filters stay on top of the skin and may be a good choice, it adds.

A MotherToBaby post from about 2015 says there is not one preferred choice for pregnant women. It found no published information that sunscreens affect the baby.

A recent peer reviewed review goes further. It calls mineral filters the usual first choice and says to avoid oxybenzone, octinoxate and 4-MBC in pregnancy to be prudent. For homosalate and octocrylene, it says the evidence is not enough to class them as acting on hormones.

The review’s authors disclose ties to ISDIN, a sunscreen maker, which paid the publication fees. It is a review, not a guideline from a health body.

Two of these sources agree on sprays. MotherToBaby says mineral sunscreens are best applied as a lotion, since a spray may be a hazard if you breathe it in. The review says to avoid mineral sprays in pregnancy when possible, for the same reason.

A dermatology journal letter found that the AAD had no sunscreen recommendations specific to pregnancy or nursing, and that advice on social media varied widely.

One more thing you may read about is a ban. MotherToBaby notes that oxybenzone is banned in some areas because it harms coral. That ban is about reefs, not pregnancy.

Which sunscreen filters are safe in pregnancy, while breastfeeding, postpartum, trying to conceive, or with PCOS?

Pregnancy and breastfeeding have the most advice on sunscreen filters among the sources cited here. The other stages have little or none.

Each row ends with what the Truva app shows for oxybenzone and zinc oxide. Those flags are Truva’s call, not a published rule.

Pregnancy

ACOG advises avoiding oxybenzone in personal care products when possible, and a review adds octinoxate and 4-MBC. The FDA has proposed both minerals as safe and effective. No body cited here has a pregnancy rule for avobenzone, homosalate, octocrylene or octisalate. The Truva app marks oxybenzone “Not Recommended” and zinc oxide “Safe to Use”. See the pregnancy list.

Breastfeeding

InfantRisk’s choice is non nano zinc oxide. It does not yet know if chemical filters reach milk in harmful amounts, and prefers chemical sunscreen to a sunburn. The review’s mineral first advice covers breastfeeding too. The Truva app marks oxybenzone “Not Recommended” and zinc oxide “Safe to Use”. See the breastfeeding list.

Postpartum, not breastfeeding

No body cited here has published a rule on sunscreen filters if you are postpartum and not breastfeeding. The Truva app marks oxybenzone “Caution Advised” and zinc oxide “Safe to Use”. See the postpartum list.

Trying to conceive

ACOG’s oxybenzone line sits on a page headed before and during pregnancy, so it is the only line here that reaches this stage. It is about personal care products and does not name sunscreen. The Truva app marks oxybenzone “Not Recommended” and zinc oxide “Safe to Use”. Truva’s trying to conceive list covers the weeks before a pregnancy is known.

PCOS

The sources cited here give no sunscreen rule for PCOS. A review in the journal Toxics says studies on PCOS outcomes remain sparse. For women it sees as most at risk, it suggests mineral filters, or newer ones that barely get into the body. It is a review, not guidance. The Truva app marks oxybenzone “Not Recommended” and zinc oxide “Safe to Use”. See the PCOS list.

Not pregnant or breastfeeding

The NHS says to use at least factor 30, use enough, and reapply often. The AAD says broad spectrum and water resistant too. The Truva app marks oxybenzone “Caution Advised” and zinc oxide “Safe to Use”. To set two labels side by side, use Compare.

Do you need sunscreen on cloudy days in pregnancy?

Yes. ACOG says the sun’s UV rays can reach you even on cloudy days.

Its reason is melasma, the dark patches some people get in pregnancy. To keep it from getting worse, it says to wear sunscreen and a wide brimmed hat every day when you are outside. It names no filter.

The NHS says you may burn more easily while pregnant. Its advice is a high factor sunscreen and not staying in the sun for long. It names no filter either.

If you want help with a bottle, take it to your midwife, doctor or pharmacist and point to the active ingredients. That is our suggestion, not a published rule.
