As summer approaches and outdoor activities increase, choosing the right sunscreen becomes essential for parents and caregivers. Sun protection plays a crucial role in preventing long-term skin damage, especially for young children, whose skin is more vulnerable to harmful UV rays.
“Establishing healthy sun protection habits early in life is critical,” says Dr. Christine Lauren, pediatric dermatologist at NewYork-Presbyterian Morgan Stanley Children’s Hospital. “Sunscreen is just one part of a broader sun safety routine. Effective protection also includes seeking shade, wearing sun-protective clothing, hats, and sunglasses.”
With countless sunscreen options available, selecting the right one can feel overwhelming. To simplify your search, Dr. Lauren shares key factors to consider when buying sunscreen, tips for proper application, and advice on how to treat sunburn if your child gets too much sun.
What kind of sunscreen do you recommend for children?
Infants under six months old should not use sunscreen. The safest approach is to keep babies out of direct sunlight and rely on protective strategies such as lightweight clothing, wide-brimmed hats, and shaded areas.
For older children, choose a broad-spectrum sunscreen. This label ensures protection against both UVA and UVB rays — the two types of ultraviolet light that damage the skin. While UVB rays cause sunburn, UVA rays contribute to premature aging and increase the risk of skin cancer. Broad-spectrum sunscreens guard against both, offering more complete sun protection.

What SPF is safest?
SPF, or Sun Protection Factor, measures how well a sunscreen shields the skin from harmful UV rays. A higher SPF means greater protection by reducing the amount of sunlight that reaches the skin. For most children, an SPF of 30 or higher provides effective coverage and is recommended by dermatologists.
Children with increased sensitivity to sunlight or a weakened immune system may benefit from a higher SPF for added protection. Always choose a sunscreen specifically formulated for kids and apply it generously and regularly, especially during extended outdoor activities.
Mineral vs. Chemical Sunscreens
Sunscreens protect the skin by using active ingredients, also known as UV filters, to block harmful sunlight. There are two main types: mineral and chemical, which can make choosing the right one confusing. Dr. Lauren explains, “All sunscreens sold in the U.S. contain FDA-approved active ingredients. While any sunscreen is better than none, especially for children, it’s important to pay attention to the specific active ingredients to ensure safe and effective protection.”
Mineral
How It Works:
Mineral sunscreens—also called physical sunscreens—sit on the skin’s surface and act as a shield, reflecting UV rays before they can penetrate. Because they create a physical barrier, mineral sunscreens begin working immediately after application.
Key Ingredients:
Mineral sunscreens use one or both of the following FDA-recognized “GRASE” (Generally Recognized as Safe and Effective) ingredients: zinc oxide and titanium dioxide. Most mineral formulas contain zinc oxide, while some include both.
Who Should Use It:
Dermatologists recommend mineral sunscreen for babies 6 months and older, young children, and those with sensitive skin or skin conditions like atopic dermatitis or eczema. It’s a top choice for anyone seeking gentle, effective protection.
Additional Considerations:
Traditional mineral sunscreens can appear thick and leave a visible white cast, especially on darker skin tones. For a more natural finish, look for products labeled “tinted,” “sheer zinc,” “clear zinc,” “micronized,” or “nanosized.”
Chemical
How It Works:
Chemical sunscreens absorb UVA and UVB rays like a sponge, converting them into heat to prevent skin damage. Unlike mineral sunscreens, they don’t sit on the skin’s surface, so they require time to become effective. Apply chemical sunscreen 15 to 20 minutes before sun exposure for best results.
Key Ingredients:
These sunscreens use a blend of chemical filters to offer broad-spectrum protection. Common active ingredients include avobenzone, oxybenzone, and octocrylene. If the label lists anything other than zinc oxide or titanium dioxide, it’s a chemical sunscreen.
Who Should Use It:
Chemical sunscreens are often preferred by older children, teens, and adults because they’re lightweight, blend easily into the skin, and don’t leave a white cast. They are generally safe for use in these age groups.
Other Considerations:
Recent studies have shown that some chemical filters may be absorbed into the body, but the health implications are still unclear. Oxybenzone, in particular, has raised concerns due to its hormone-disrupting effects in animal studies. While the FDA continues to recommend sunscreen use to protect against skin cancer, parents concerned about absorption can choose mineral-based options with zinc oxide or titanium dioxide for peace of mind.
How much sunscreen should you apply?
One common reason people still get sunburned is not using enough sunscreen. For effective protection, apply approximately one ounce of sunscreen per application — about the amount that fits in a standard shot glass. This guideline applies to covering an average adult’s entire body. Using too little significantly reduces the sunscreen’s effectiveness, leaving skin exposed to harmful UV rays.
How often should you reapply sunscreen?
Apply sunscreen before heading out for the day, ideally 15–30 minutes before sun exposure. To maintain protection, reapply every two hours when outdoors—more often if you’re swimming or sweating. Sunscreen labeled “water resistant” stays effective for up to 40 minutes in water, while “very water resistant” formulas last up to 80 minutes. Always reapply immediately after towel-drying, swimming, or excessive sweating to ensure continuous coverage.
Do you recommend spray, stick or lotion?
The best sunscreen is the one your child will actually use. With a variety of creams, lotions, sticks, and sprays available, it’s important to choose a formula that fits their routine and comfort.
Sunscreen sticks are a convenient option, especially for kids at camp or playing sports, since they’re pocket-sized and easy to reapply to exposed skin.
Spray sunscreens, while popular, come with some caution. They often don’t apply evenly and may pose a risk if inhaled during application. If you choose a spray sunscreen, avoid spraying it directly on your child. Instead, spray it into your hands and then rub it onto their skin to ensure even coverage and reduce inhalation risk.
What areas do kids usually miss when applying sunscreen?
Certain areas—like the back, neck, and ears—are often missed during sunscreen application, especially when children wear baseball caps instead of wide-brimmed hats. The back is particularly vulnerable, especially in boys, and sunburns are common when sun-protective clothing isn’t used.
This highlights the importance of a comprehensive sun protection strategy. In addition to sunscreen, prioritize seeking shade, especially during peak UV hours between 10 a.m. and 4 p.m. Also, incorporate sun-protective clothing into your child’s daily routine. These garments provide reliable protection, especially when shade isn’t available. Many popular brands now offer UPF-rated swimwear and clothing that are both stylish and athletic, making sun safety easier and more appealing.
Do children need sun exposure to get enough vitamin D?
Vitamin D plays a vital role in overall health, but that doesn’t mean you should skip sun protection. It’s entirely possible to maintain healthy vitamin D levels while still shielding your skin from harmful UV rays. Health experts recommend daily vitamin D supplementation to ensure you’re getting the right amount—regardless of sun exposure. This approach allows you to protect your skin without compromising your body’s nutritional needs.
If your child is sunburned, what are the best treatments?
For mild sunburn—marked by redness and warmth—apply cool compresses or give your child a cool bath to relieve discomfort. Over-the-counter medications like ibuprofen or acetaminophen can help reduce pain and inflammation. Topical remedies containing aloe vera or colloidal oatmeal can also soothe irritated skin.
If your child shows signs of a more serious sunburn—such as fever, blisters, intense pain, or feeling generally unwell—it’s important to contact your pediatrician. These symptoms may require wound care, infection prevention, or additional medical support.
Don’t forget: hydration is key. Severe sunburn can lead to dehydration, so encourage your child to drink plenty of fluids during recovery.
