Sunscreen Ingredients to Avoid During Pregnancy

Pregnancy changes how you read a label. Foods, skincare, and yes, sunscreen. The reason sunscreen is worth a second look is simple: some UV filters absorb through the skin into the bloodstream, and the FDA has asked for more safety data on most of them. Here are the ingredients many people choose to skip while pregnant, and the plain-language reason why.

What the FDA review means

Sunscreen is regulated as an over-the-counter drug. Of the 16 UV filters allowed in the US, the FDA has confirmed only two as Generally Recognized as Safe and Effective: zinc oxide and titanium dioxide, both minerals. For the other filters, most of them chemical, the FDA has said it does not yet have enough data to make that call and has requested more.

That is an important distinction. It does not mean those ingredients are unsafe. It means the safety question is open. Absorption studies have shown that several chemical filters enter the bloodstream at measurable levels after normal use. During pregnancy, when many people prefer to limit unknowns, an open safety question is often reason enough to choose the filters that are settled.

Chemical filters people commonly avoid while pregnant

None of these are banned, and this is not a claim that any of them causes harm. Each is simply a filter the FDA has flagged for more data, which is why they show up on so many "avoid while pregnant" lists.

Oxybenzone (Benzophenone-3)

The most talked-about one. It absorbs into the bloodstream more than most filters, and it has been detected in studies looking at systemic exposure. The FDA has requested more safety data on it. It is the ingredient most people are thinking of when they switch to mineral for pregnancy.

Octinoxate (Octyl Methoxycinnamate)

A common UVB filter that also shows measurable skin absorption. Like oxybenzone, it is on the FDA's list of actives awaiting more safety data.

Homosalate

A UVB filter used in many chemical sunscreens. The FDA has proposed limiting its concentration pending more information about how much absorbs and what that means. Another one in the "needs more data" bucket.

Avobenzone

The main chemical UVA filter. It is not the most concerning on the list, but it absorbs, it can be unstable on its own, and it is part of the same group the FDA is still reviewing.

Two more things to skip

Beyond the actives, two inactive ingredients are worth avoiding during pregnancy for comfort reasons more than safety ones:

• Fragrance. Pregnancy skin is often more reactive, and fragrance is a leading cause of irritation. There is no reason a daily sunscreen needs it.
• Heavy synthetic extras. Long ingredient lists mean more things your skin is reacting to. Fewer, readable ingredients make it easier to know exactly what you are putting on every day.

Why pregnancy raises the stakes

Two reasons daily sun protection matters even more right now. First, hormones make the skin more prone to melasma, the patchy darkening sometimes called the mask of pregnancy, and sun exposure is its main trigger. (More on that in our guide to sunscreen for melasma.) Second, this is the season of life when most people most want to know exactly what is going onto their skin and into their body. Both point the same direction: a short, settled formula you can wear every day.

What to use instead

A mineral sunscreen with non-nano zinc oxide as the only active. Zinc oxide is one of the two FDA-confirmed GRASE filters, it sits on the surface of the skin rather than absorbing systemically, and it covers the full UVA and UVB range on its own. Pair that with a short, fragrance-free ingredient list and you have removed the open questions instead of guessing at them. Our companion guide goes deeper on the science: is zinc oxide sunscreen safe during pregnancy.

Where Swellies fits

Swellies is a five-ingredient mineral sunscreen, and the list is the whole point here:

• Zinc Oxide (non-nano), 21%. The only active. FDA Category I, GRASE-confirmed, full UVA and UVB coverage.
• Coco Caprylate/Caprate. A lightweight plant-derived carrier.
• Dextrin Palmitate. Turns the formula into a breathable gel.
• Polyhydroxystearic Acid. Spreads the zinc evenly, so no white cast.
• Iron Oxides. A sheer mineral tint that also blocks high-energy visible light.

No oxybenzone, no octinoxate, no homosalate, no avobenzone. No fragrance, no preservatives, no silicones. Broad spectrum SPF 46, water resistant 40 minutes. Five ingredients you can read, which is exactly what you want when you are reading every label.

One honest note. This is general information, not medical advice, and it is not a claim that any sunscreen is or is not safe for your pregnancy. Every pregnancy is different. Bring your sunscreen, or any product you are unsure about, to your OB or midwife and let them make the call for you.

Frequently asked questions

What sunscreen ingredients should I avoid during pregnancy?

Many people choose to skip the chemical UV filters the FDA has flagged for more safety data, most commonly oxybenzone, along with octinoxate, homosalate, and avobenzone. Fragrance is worth avoiding too, since pregnancy skin is often more reactive. Talk to your provider about your specific situation.

Is mineral sunscreen safe to use during pregnancy?

Mineral sunscreens use zinc oxide or titanium dioxide, the two filters the FDA has confirmed as Generally Recognized as Safe and Effective. Zinc oxide sits on the skin rather than absorbing into the bloodstream, which is why it is the active many OB/GYNs point to. Your provider is the right person to confirm what is best for you.

Why is oxybenzone on so many pregnancy avoid-lists?

Because it absorbs into the bloodstream more than most filters and the FDA has requested more safety data on it. The safety question is open, not settled, and during pregnancy many people prefer to avoid the open questions. That is a personal and medical choice, not a verdict that the ingredient is harmful.

Should I wear sunscreen every day while pregnant?

Daily sun protection is worth it, especially because pregnancy hormones make skin more prone to melasma, and sun exposure is its main trigger. A gentle mineral sunscreen with a short ingredient list makes daily wear easy.
