What sunscreen ingredients should I use during pregnancy?

Look for zinc oxide or titanium dioxide in the active ingredient list. These are mineral sunscreen filters, also called physical filters. Choose a fragrance free formula to reduce the risk of irritation, and check the rest of the ingredients rather than choosing by the product name alone.12

Broad spectrum means protection against both UVA and UVB, the two types of ultraviolet radiation. SPF mainly measures protection against sunburn from UVB, so a high number does not replace the broad spectrum claim. Choose SPF 50 or higher for extended outdoor activities. An impressive SPF number is only part of the label, not the whole job description.23

Is mineral sunscreen safe during pregnancy?

Mineral sunscreen is a recommended choice during pregnancy, particularly for sensitive skin. Zinc oxide and titanium dioxide stay on the skin's surface and primarily absorb ultraviolet radiation, with a smaller amount scattered or reflected. Mineral formulas can be less irritating than chemical formulas, but choose for comfort as well as protection: a sunscreen you are willing to apply consistently is more useful than one you leave untouched.2

Can I use my regular sunscreen while pregnant?

If your regular sunscreen meets those requirements and contains mineral filters, it fits the pregnancy guidance. Chemical and mixed filter formulas need a separate ingredient check; the preference for mineral sunscreen does not mean every chemical sunscreen is dangerous. Some sunscreen filters enter the body through the skin, and safety questions remain for several filters. For a straightforward choice without sorting through those uncertainties, switch to a mineral formula.134

In the US, additional safety data have been requested for filters including avobenzone, oxybenzone and octocrylene. That is different from a finding that they cause harm during pregnancy. Sunscreen use remains recommended alongside clothing and shade.5

Check combination skincare products too. Avoid products containing retinoids, including retinol, and hydroquinone during pregnancy. Tell your obstetrician or dermatologist about prescription skincare and medications so your treatment plan can be updated.1

How should I apply sunscreen during pregnancy?

  1. 1Apply sunscreen every day before going outdoors. Follow the label; general application guidance is to apply 15 minutes before sun exposure.
  2. 2Cover all exposed skin evenly. Include your ears, neck, hands, tops of your feet, hairline and exposed scalp. Use SPF lip balm for your lips.
  3. 3Use enough product. An average adult needs about one ounce to cover the entire body; that is not the amount needed for the face alone.
  4. 4Reapply at least every two hours while outdoors, and more often when swimming or sweating. Follow the water resistance and reapplication directions on the label.

Water resistant sunscreen is tested for either 40 or 80 minutes of swimming or sweating. No sunscreen is waterproof.3

What if pregnancy has brought on dark patches?

Pregnancy can trigger melasma, patches darker than your usual skin tone, and sun exposure can worsen pregnancy related pigmentation. A tinted mineral sunscreen can add protection against visible light, which also contributes to pigmentation. A tint can also camouflage uneven colour, giving the sunscreen a second job without adding another bottle. The extra visible light protection can be particularly useful for darker skin tones.4

Use shade, a broad brimmed hat and clothing alongside sunscreen, and limit sun exposure between 10 a.m. and 2 p.m. Keep the bottle out of excessive heat and direct sunlight. Replace expired sunscreen, or a bottle with no expiry date once three years have passed since purchase. If sensitivity or pigmentation becomes difficult to manage, a dermatologist can help you choose suitable care.13
