What Kind of Sunscreen Is Best for Pregnant People?

As any pregnant person will tell you, the list of things that are off-limits during pregnancy is a lengthy one— from supplements to topical acne creams, theres a lot of product swaps that need to be done. But, if weve learned one thing, its that sunscreen should always be a non-negotiable regardless of whether its raining or youre staying indoors, etc. Which brings us to the question: what kind of sunscreen works best for pregnant people? Are there any ingredients that are off-limits?

While things such as retinoids and benzoyl peroxide are clear no-nos, when it comes to sunscreen, the lines are a little blurrier. Make no mistake, you absolutely can—and most definitely should—be using sunscreen while youre both pregnant and breastfeeding, but it is important to be a bit more selective about the type.

Ahead, dermatologists Stacy Chimento, MD, and Dr. Jessie Cheung, MD, explain everything parents-to-be should be mindful of when choosing their SPF.

Types of Sunscreen

Lets start with a quick refresher as to the different types of sunscreens out there. There are two categories: chemical and physical (the latter of which are also referred to as mineral sunscreens). Chemical sunscreens contain ingredients— the most commonly include avobenzone, oxybenzone, and homosalate—that are absorbed into the skin. There, they work by absorbing UV rays and converting them into heat, which prevents the skin from burning, explains Dr. Chimento. On the other hand, physical sunscreens, which rely on minerals such as zinc oxide and titanium dioxide, are not absorbed into the skin. Rather, they sit on the surface and work by reflecting or redirecting the damaging UV rays, she says.

Physical Vs. Mineral Sunscreen

Broadly speaking, they each have their own sets of pros and cons. For example, chemical sunscreens are traditionally more cosmetically elegant, while physical sunscreens tend to be less irritating for those with sensitive skin. If youre not pregnant, the best sunscreen for you is the one that you like and are going to actually use every day, 365 days a year. (Because yes, you need to wear sunscreen every single day.) That being said, for those who are pregnant, there is a clear winner and well tell you why.

Which Types of Sunscreen Should Pregnant People Avoid?

Both dermatologists we spoke with agree that physical sunscreens are by far the better option for pregnant people. "There are ongoing studies about the safe threshold for the absorption of chemical sunscreen ingredients through the skin, which show that they can get into the bloodstream," says Dr. Cheung. Indeed, in January of 2020, the Food and Drug Administration (FDA) released a study in the Journal of the American Medical Association that found six commonly-used chemical sunscreen ingredients are absorbed into the body; these findings prompted further research about the safety of these ingredients, which is still ongoing. Dr. Cheung goes on to say that oxybenzone, octinoxate, and homosalate in particular have been shown to impact hormones in animal studies.

But thats by no means an excuse to skip SPF, pregnant or not. It just means that pregnant people (as well as anyone who may be concerned about systemic absorption of the ingredients in question) should stick with physical formulas. "Physical sunscreens simply sit on top of the skin, so theres no concern around chemicals being absorbed and affecting either parent or baby," says Dr. Chimento. Its also worth noting that the two most commonly used ingredients in physical sunscreens, zinc oxide and titanium dioxide, are the only two sunscreen ingredients deemed GRASE (generally recognized as safe and effective) by the FDA.

Does This Apply to Those Who Are Breastfeeding?

In a word, yes. The chemicals in question can get into both the bloodstream and breast milk, says Dr. Cheung. "Physical sunscreens are inherently safer for those who are breastfeeding and for their babies, both while pregnant and breastfeeding," she explains.

The Best Sunscreens for Those Who Are Pregnant and/or Breastfeeding

While physical sunscreens previously had a bad rap for being thick and chalky, the latest formulas are lightweight and apply beautifully. Here are a few dermatologist favorites.

Dr. Chimento is a fan of CeraVes Hydrating Mineral Sunscreen ($13), a drugstore staple. She lauds it not only for its mineral sun protection but also for being very hydrating, a boon for pregnant people who often experience dry skin, she says. Its also allergen-free and very gentle, so much so that it boasts the National Eczema Associations seal of approval—great for anyone prone to irritation.

"This foaming sunscreen is weightless, easy to apply, and dries quickly," says Dr. Cheung of TiZos Sheerfoam Mineral Sunscreen SPF 30 ($40). Also nice: It can be used on both the face and body.

Dr. Cheung also likes EltaMDs UV Elements Tinted Broad-Spectrum SPF 44 ($40), which "has a subtle tint for a little extra coverage." The all-mineral formula contains hyaluronic acid to help hydrate, though is both oil-free and non-comedogenic, a great pick for anyone battling pregnancy-induced acne.

"I like this for pregnant people because its fragrance-free, making it even safer for baby," says Dr. Chimento of La Roche-Posays Anthelios Body and Face Gentle Mineral Sunscreen SPF 50 ($33). (FYI, fragrance is another one of those ingredients that its good to avoid during pregnancy.) It can be used on both the body and face, too, making it very convenient, she adds.

Isdins Mineral Brush Powder ($55) is a very fine powder sunscreen that doesnt look cakey, and also contains iron oxides that protect the skin from damaging blue light and infrared radiation as well as UV rays, says Dr. Cheung. Its great for re-application over makeup (as a reminder, youre supposed to reapply sunscreen every two hours, especially when youre outdoors) and for brushing into the hairline and part, two often-forgotten spots.

The Takeaway

Anyone and everyone—pregnant and breastfeeding people included—should undoubtedly be using sunscreen every single day, no ifs, ands, or buts about it. For those who are pregnant or breastfeeding, physical sunscreens—those with zinc oxide or titanium oxide as the active ingredient, which are chemical-free and dont absorb into the skin—are the safest and best option. And given the amount of new, cosmetically elegant formulas on the market, there are plenty of great, safe, sunscreens to choose from.

That being said, if youre in a bind and the only sunscreen available is a chemical option, thats better than no sunscreen at all, says Dr. Cheung.  "As long as the exposure is short-term and intermittent, the resulting concentration of chemicals in the body is very little and below the safe threshold," she says. "Application of a chemical sunscreen is always safer than a potential sunburn." Just make sure that youre using mineral sunscreens the majority of the time.
