Whether you’re enjoying a family beach day or making a quick stop at the playground, the best baby sunscreen should always be in your diaper bag. The sun’s ultraviolet rays can burn skin in as little as 15 minutes — even when it’s cloudy — and early-in-life sunburns greatly increase the risk of skin cancer down the road. Protecting kids from the sun, with sunscreen, appropriate clothing, and shade, is crucial for preventing long- and short-term sun damage. The best sunscreen for babies, toddlers, and kids keeps them protected from the sun’s damaging rays, is safe for little bodies, and gentle on the environment, particularly delicate marine ecosystems.

For infants under 6 months old, protection means keeping them out of the sun completely. “Sun exposure can be extremely dangerous for babies due to their thin skin and relative lack of melanin, the skin pigment that provides some sun protection,” Anna L. Chien, M.D., a board-certified dermatologist in Baltimore and spokesperson for the Skin Cancer Foundation, told Fatherly. But because babies’ skin is so sensitive, she says, even baby sunscreen can be too irritating. When the sun can’t be avoided, dress infants in long sleeves and pants and a wide-brimmed hat or bonnet, and use a stroller with a canopy or hood.

Children 6 months and up, however, should wear sunscreen — in addition to seeking shade and wearing hats, sunglasses, and sun-protective clothing that covers as much skin as possible. But with so many different sunscreens for kids on the market, how do you choose?

What You Need to Know About Sunscreen for Kids When it comes to selecting the best sunscreen for your kids, there are a few hard-and-fast rules that experts across the board agree on. Check the SPF : Any sunscreen you put on your kids should be SPF 30 or higher. Short for “sun protection factor,” SPF is a measure of a product’s ability to prevent ultraviolet B rays from burning skin. While you’ll find products with SPF all the way up to 100, studies have shown that the level of additional UVB protection you’ll get above SPF 30 is minimal.

Look for “Broad-Spectrum” : Because SPF applies to only UVB rays — and not ultraviolet A rays — the second thing to look for on labels is “broad-spectrum.” This means the sunscreen will safeguard against both UVB and UVA rays, the type that penetrates the skin more deeply to cause wrinkles, age spots, and that leathery look. UVA rays are also the main culprits in skin cancer, from deadly melanoma to the all-too-common basal and squamous cell carcinomas.

Choose Water-Resistant : Third, look for a sunscreen labeled “water-resistant,” especially if the kiddos will be swimming or sweating. Because no sunscreen is truly waterproof, the FDA no longer allows brands to make that claim. But if companies have tested and shown that their product can remain effective in water for up to 40 or 80 minutes, then they can legally use the term “water-resistant” on labels, followed by the tested-for time frame.

Apply Properly : None of these factors matter if sunscreen isn’t applied properly. “To achieve full efficacy, it is crucial to use enough sunscreen, not spread it too thin, and reapply,” Chien says. “Thirty minutes before kids go outside, apply to all exposed areas of the body not covered by clothing, such as the face, ears, neck, and back of the hands. Reapply every two hours, or more frequently if your child is going in the pool or sweating.”



Choose a Cream or Lotion Over Spray or Stick: Experts recommend lotions and creams over spray and stick sunscreens, in order to guarantee full coverage, at least for the first application. “A big problem with spray sunscreens is people miss areas and you don’t get an even application — and you don’t want to inhale it,” Anna Bender, M.D., assistant professor of dermatology at Weill Cornell Medical College in New York, told Fatherly. “Start with a sunscreen cream or lotion; then sprays are okay for touch-ups. Just use them in a well-ventilated area and rub them in afterwards.” Bender says sunscreen sticks are fine for touchups as well, as long as you swipe each area at least twice to ensure adequate coverage.

Chemical Versus Mineral Sunscreen for Kids

Once you’ve narrowed the options down to just water-resistant, broad-spectrum lotions and creams that are SPF 30 or higher, there is still a mind-boggling array of sunscreens to choose from. Now your decision comes down to active ingredients, which you’ll see listed in a box on the back of the bottle.

Active sunscreen ingredients fall into two basic categories: chemical and mineral. Chemical ingredients, such as oxybenzone, avobenzone, octinoxate, octisalate, octocrylene, and homosalate, work by forming a thin film on the skin that absorbs, and therefore disarms, UV rays. Except for oxybenzone, which by itself is broad-spectrum, each of these chemicals absorbs either only UVA or only UVB rays — not both — which is why they are rarely used alone. Instead, sunscreen brands usually combine two or more chemicals to create a broad-spectrum product.

Then there are two mineral sunscreen ingredients: zinc oxide and titanium dioxide, which work in an entirely different way than their chemical counterparts. Rather than absorb UV rays, they sit on the top layer of skin and physically reflect, scatter, and block them, says Chien. And unlike most chemical ingredients, zinc oxide and titanium dioxide each guard against both UVA and UVB rays.

Whether you’re looking at the label of a mineral or chemical-based sunscreen, you’ll see a percentage listed after each active ingredient. These refer to the concentration of the ingredient, but dermatologists say to not worry too much about them.

“I usually don’t guide by percentages because while, ideally, you’d want to aim for the highest percentage, higher percentages also mean the sunscreen will be thicker and harder to rub in,” Ivy Lee, M.D., board-certified fellow of the American Academy of Dermatology and adjunct clinical assistant professor of dermatology at the University of Southern California Keck School of Medicine, told Fatherly. “Also, the higher percentages sometimes lull people into thinking they don’t need to reapply. Instead of focusing on percentages, look at the active ingredients and whether the sunscreen is broad spectrum.”

Which Sunscreen Is Best for Kids?

While the Food and Drug Administration, which regulates sunscreens, considers 13 different chemical ingredients and both mineral ingredients to be safe and effective, all of the dermatologists Fatherly spoke with prefer mineral sunscreens for kids, for a number of reasons.

“I like mineral for simplicity’s sake,” Lee says. “Both titanium dioxide and zinc oxide are broad spectrum, whereas, with chemicals, some are more effective than others so it depends on combination to offer broad-spectrum coverage. Also, because mineral sunscreens tend to be opaquer, you know exactly where you have applied and where you haven’t, and they are easy for kids to apply themselves.”

Mineral sunscreens are also less likely to irritate kids’ skin than chemical products because they sit on top of the skin versus soaking in. “Kids can get allergic contact dermatitis to the active ingredients in sunscreen, which is more likely with chemical sunscreens than mineral,” Lee says. “But the preservatives can also cause irritation. That’s why I recommend sticking with simple, bland but effective ingredients such as zinc oxide and titanium dioxide.”

Parents should also know that a sunscreen that doesn’t bother adult skin could easily trigger a kid’s skin. “Children have more sensitive skin than adults; therefore, mineral sunscreens are a better option for them,” Chien says. “You may want to test sunscreen on the inside of your child’s wrist. If they have a little irritation, try another sunscreen.”

It is mainly because of the skin-sensitivity issue that certain sunscreens are marketed specifically for kids or babies. But in most cases, this merely means that the product is made with active mineral ingredients instead of chemicals; there may also be no fragrances, minimal preservatives, or other potentially irritating components in the lotion. But a “kid” or “baby” designation does not necessarily speak to the efficacy of the product. Therefore, when shopping for sunscreens, don’t feel limited to only those marketed for youngsters.

The main knock against mineral sunscreens has always been their cosmetic appeal. “Mineral, or physical, sunscreens tend to be thicker and may leave a white cast behind,” Chien says. “However, many new formulations are micronized, meaning the product’s particles are small enough to blend and disappear into the skin more easily.”

Are Chemical Sunscreens Safe for Kids?

Despite chemical sunscreens’ GRASE status, concerns have been raised about a few in particular. Most notably, oxybenzone, one of the most commonly used because of its ability to absorb both UVA and UVB rays, has come under fire. Preliminary studies conducted on animals have suggested that oxybenzone could mess with hormonal systems within the body, while observational analyses of humans have revealed a potential link between the chemical and lower testosterone levels and lower birth weights.

However, while this preliminary data is worth noting, it is far from definitive and does not prove that oxybenzone poses a real health threat to humans. “Old research, where oxybenzone was force-fed to immature rodents, suggested that oxybenzone may cause hormone disruption,” Chien says. “But topical application by humans does not equal the oral dosage administered to the rodents. More recent human studies have shown absolutely no change in hormonal levels in individuals using sunscreens containing oxybenzone.”

Bender is also not worried about oxybenzone posing a health threat, especially since we regularly excrete it via urine versus it accumulating in the body like many other chemicals do. Still, for parents who want to be extra cautious given the research, this could be yet another reason to choose mineral sunscreen for kids over products containing oxybenzone.

So, for now, oxybenzone, homosalate, octocrylene, and other chemical sunscreens are still considered safe and effective.

The Environmental Impact of Sunscreen

While the health risks associated with chemical sunscreens may be unproven, those aren’t the only concerns about them. Many have the potential to harm aquatic ecosystems. Since they are not easily removed by wastewater treatment systems, these chemicals inevitably end up in waterways—in addition to the sunscreen chemicals that go directly into lakes, rivers, and oceans when they come off of our bodies while we swim and recreate.

In fact, according to the National Park Service, up to 6,000 tons of sunscreen enters coral reef areas annually. Studies have shown that oxybenzone and octinoxate, specifically, bleach out the coral, potentially causing irreparable harm to these already delicate ecosystems. These chemicals have also been detected in the bodies of fish around the globe, which could negatively impact food chains.

Citing these grave ecological concerns, Hawaii and the Western Pacific nation of Palau both banned the sale of sunscreens containing oxybenzone and octinoxate in 2018. Key West, Florida, followed suit earlier this year, and a similar ban has been proposed in California. Outdoor retailer REI has agreed to stop selling oxybenzone sunscreens starting in 2020.

Due to growing awareness of the environmental issues associated with oxybenzone and octinoxate, some sunscreens not containing either ingredient are now claiming to be “reef safe.” However, according to Consumer Reports, there is no agreed-upon or government-regulated definition for this term. Additionally, oxybenzone and octinoxate are simply the most studied of the sunscreen chemicals—others may very well impose similar damage on coral reefs. If this is a concern, your best bet is to stick with products made with zinc oxide or titanium dioxide, which are not as ecologically harmful.
