The Safest Non Toxic Sunscreen For Kids & Babies

As a mom of three, nothing is more important to me than the health and well-being of my little ones.

That’s why I’ve made it my mission to find the least toxic skincare formulas for my kids, including natural sunscreen for babies and toddlers.

With so many products on the market, each claiming to be the best, I’ve spent countless hours pouring over ingredient lists, researching different formulations, and testing out various products to find the absolute best options for my children. Greenwashing is a huge issue in the industry. 

My non-negotiable criteria are strict, just like most parents.

• I look for organic baby sunscreen formulas that are free from harsh chemicals, synthetic fragrances, and potentially harmful additives. 

• I prioritize safe options that provide broad-spectrum protection without the use of chemical UV filters. Mineral-based sunscreens with ingredients like non-nano zinc oxide or titanium dioxide, which form a physical barrier against the sun’s rays without absorbing into the skin. 

• And, lastly, the reef-safe sunscreen for kids should be hypoallergenic and safe for the most sensitive skin types. 

In this guide, we won’t just go over the best non-toxic sunscreen for toddlers and babies. You’ll learn exactly how to vet and verify the formulas, what ingredients are a no-no, and the best alternatives. 

So, let’s get into it.

Mineral vs. Chemical Sunscreen, what’s the difference?

The term “non toxic sunscreen for kids” is basically synonymous with mineral sunscreen. But what’s the difference between mineral and chemical sunblock? Is it really better for our little ones?

Here’s what you need to know:

Mineral sunscreens, also known as physical sunscreens, are formulated with active ingredients like zinc oxide and titanium dioxide. These ingredients work by forming a protective barrier on the skin’s surface, to reflect and scatter UV rays away from the skin.

Parents choose natural sunblock for kids because they are safer for sensitive skin. After all, they are less likely to cause irritation or allergic reactions.

On the other hand, chemical sunscreens contain active ingredients such as avobenzone, oxybenzone, octinoxate, and octocrylene. These chemicals absorb UV rays and convert them into heat, which is then released from the skin.

While chemical sunscreens can be effective, they have raised concerns about potential hormone disruption and skin irritation, especially for children with sensitive skin. 

For example, a study published in the Journal of the American Academy of Dermatology found that mineral sunscreens, specifically those containing zinc oxide, were less likely to cause skin irritation than chemical sunscreens.

Chemical sunscreens are also notorious for causing coral bleaching and damage to marine ecosystems, leading to bans on certain chemical sunscreen ingredients in areas like Hawaii and Key West, Florida.

So, natural mineral sunscreen for babies and kids is a better option for the skin and the planet.

The Most Toxic Ingredients To Avoid  in Kids Sunscreen

You’d think that all kids skincare should be 100% safe. But, unfortunately, that’s not the case.

As EWG pointed out, children are exposed every week to one or more ingredients that may disrupt the hormone system, including ingredients and chemicals classified as known or probable human carcinogens. Sunscreen is one of those products. 

Oxybenzone

Oxybenzone is a chemical UV filter that absorbs UVB and UVA rays, converting them into heat and then releasing them from the skin. It is primarily used to protect the skin from sunburn and UV-induced damage.

However, oxybenzone has been associated with hormone disruption, allergic reactions and and has even been linked to Hirschsprung’s disease. Furthermore, both oxybenzone and octinoxate are harmful to coral reefs, leading to bans in various regions to protect marine ecosystems.

Octinozate

Also known as octyl methoxycinnamate, octinoxate is another chemical UV filter that absorbs UVB rays. It helps prevent sunburn by absorbing and dissipating UV radiation.

However, like oxybenzone, octinoxate has been linked to hormone disruption and environmental harm. This is one reason why both chemicals are not recommended for use during pregnancy, breastfeeding, or on children under the age of 2.

Homosalate

Homosalate is a chemical UV filter primarily used to absorb UVB rays. It helps protect the skin from sunburn and is often included in sunscreen formulations for its UV-absorbing properties.

Research suggests that homosalate can disrupt estrogen, androgen, and progesterone activity, potentially leading to reproductive and developmental issues.

In 2021 the European Commission found that homosalate and octocrylene, which will be discussed later,  are not safe in the amounts at which they’re currently used in sunscreens.

Octisalateis

Octisalateis another UV filter, commonly found in chemical sunscreen that is less harmful than some other chemical sunscreen ingredients but can still cause skin irritation and allergic reactions in sensitive individuals. That’s because octisalate is systemically absorbed into the body after use, according to studies published by the FDA.

Harsh Preservatives

Preservatives like parabens (such as methylparaben, ethylparaben, propylparaben, and butylparaben) and phenoxyethanol are commonly used in skincare products, including kids sunscreens, to extend shelf life.

While they do what they promise — help maintain the stability and efficacy of the product over time –  they have been associated with hormone disruption, allergic reactions, and skin irritation.

Parabens, in particular, have been detected in human breast cancer tissues, raising concerns about their potential role in breast cancer development.

Nanoparticles

Nanoparticles of titanium dioxide and zinc oxide are used in mineral sunscreen formulations to provide broad-spectrum UV protection. These nanoparticles are engineered to scatter and reflect UV radiation away from the skin, acting as physical barriers.

While most studies indicate that nanoparticles are safe for topical use, there are concerns about their potential to penetrate the skin and cause cellular damage.

Formaldehyde Releasers

Formaldehyde-releasing preservatives like DMDM hydantoin and quaternion-15 are added to sunscreen formulations to prevent microbial contamination. These chemicals slowly release formaldehyde into the skin, which acts as a preservative.

However, formaldehyde is a known carcinogen and can cause allergic reactions and skin sensitivities. We’ve seen studies linking them to leukemia and the promotion of tumor formation.

Fragrances

Fragrances are added to sunscreen formulations to, you guessed it, make them smell nice. But, many fragrance formulations contain a cocktail of potentially harmful chemicals, including phthalates, which have been linked to hormone disruption and reproductive issues.

Fragrance formulations are considered trade secrets and are not required to be disclosed on product labels. That makes it challenging for parents to identify and avoid them.

The best non-toxic sunscreen for kids is completely free from these chemicals!

What sunscreen ingredients are safe for kids?

If you want to make sure that you’ve picked the least toxic sunscreen for kids and babies, solely opt for natural formulas that include these safe ingredients:

Zinc Oxide

Zinc oxide is a mineral UV filter that provides broad-spectrum protection against both UVA and UVB rays. It works by forming a physical barrier on the skin’s surface, reflecting and scattering UV radiation away from the skin.

It’s the main ingredient in most natural children’s sunscreen formulas because it can effectively replace harmful chemicals like avobenzone, oxybenzone, octinoxate, and octocrylene, and it’s gentle on sensitive skin and does not cause irritation or allergic reactions.

Titanium Dioxide

Like zinc oxide, titanium dioxide is a mineral UV filter that offers broad-spectrum protection against UVA and UVB rays. It works by reflecting and scattering UV radiation away from the skin, providing a physical barrier against sunburn and UV-induced damage.

Titanium dioxide is used in most natural sunscreen for babies and kids, although some formulations may contain nanoparticles, which can raise concerns about potential skin penetration.

So, make sure that the non-toxic sunblock for kids you’re about to purchase is free from nanoparticles. It should be clearly stated on the website. 

How to know if a non-toxic sunscreen is safe for kids’ sensitive skin?

Kids’ skin is way more sensitive than ours because it’s thinner. Basically, their immune system has not fully developed yet, so they are more susceptible to rashes and allergic reactions.

So, when picking the absolute safest non-toxic sunscreen for babies and kids, keep in mind:

1. Look for sunscreen labels that boast being hypoallergenic and specifically formulated for sensitive skin. These natural children’s sunscreen formulas are designed to minimize the risk of allergic reactions and irritation, making them a great choice for kiddos with sensitive skin.
2. Always choose mineral-based sunscreens with active ingredients like zinc oxide or titanium dioxide. These gentle minerals sit on the skin’s surface and form a physical barrier against the sun’s rays, making them less likely to irritate chemical sunscreens.
3. To be 100% sure that the sunblock is free from all harmful chemicals, grab organic baby sunscreen and certified children’s formulas that have been vetted by EWG. They give products a rating of 1-10 to reflect both the degree of protection from the sun’s ultraviolet radiation and the hazards of all ingredients on the label.
4. When in doubt, do a patch test before slathering sunscreen all over your child’s body. Apply a small amount of sunscreen to a small area of their skin and wait 24 hours to see if any redness, itching, or irritation occurs. If their skin reacts negatively, it’s a sign that the sunscreen may not be suitable for their sensitive skin.

Effective Sun Protection Tips For Parents 

Remember, the absolute best non-toxic sunscreen for kids and babies cannot be 100% effective if you aren’t making sure that you’re also following safe sunscreen practices.

1. Purchase a mineral-based non-toxic sunscreen to enjoy effective broad-spectrum protection without the use of harsh chemicals, making them safe for your child’s delicate skin.
2. Between 10 am and 2 pm, the sun’s rays are the strongest and most harmful. Seek shade during these peak hours to reduce your child’s exposure to UVA and UVB rays. You can set up a sun umbrella or find sheltered areas to keep your family protected from the sun’s intense rays.
3. In addition to seeking shade, take extra precautions to minimize sun exposure. Encourage your child to play in shaded areas, and consider planning outdoor activities in the early morning or late afternoon when the sun is less intense.
4. Dress your child in sun-protective clothing that covers their skin, such as long-sleeved shirts, pants, and wide-brimmed hats.  
5. Don’t forget to protect your child’s eyes from harmful UV rays with sunglasses with UV protection. Sunglasses labeled with 100% UV protection or UV 400 to shield their eyes from both UVA and UVB rays.
6. Apply sunscreen to all exposed skin areas, including the face, neck, ears, and hands. Use a generous amount of sunscreen and reapply every two hours, or more frequently if your child is swimming or sweating.

Remember to keep your child hydrated, especially when spending time outdoors in the sun. Remind them to drink plenty of water throughout the day to prevent dehydration and keep their skin healthy and hydrated. Having a water bottle in your bag at all times is a lifesaver – literally.

What level of SPF is best for babies and kids?

When it comes to choosing the right SPF for babies and kids, experts generally recommend using a broad-spectrum sunscreen with an SPF (Sun Protection Factor) of at least 30.

The best non-chemical sunscreen for babies and kids with SPF 30 provides adequate protection against both UVA and UVB rays, helping to prevent sunburn, skin damage, and long-term sun-related skin issues.

For babies under six months old,  consult with a pediatrician before using sunscreen. In most cases, pediatricians recommend keeping infants under six months out of direct sunlight and using protective clothing, hats, and shade to shield their delicate skin from the sun’s rays.

How often should I reapply sunscreen on my child?

1. Every two hours: It’s recommended to reapply sunscreen every two hours, regardless of whether your child is swimming, sweating, or staying dry. Sunscreen can wear off over time, especially when exposed to sunlight and outdoor elements, so reapplying ensures continuous protection throughout the day.
2. After swimming or sweating: If your child is swimming or engaging in activities that cause them to sweat heavily, reapply sunscreen even more frequently. Water-resistant sunscreen provides some protection while in the water, but it can still wear off over time, so be sure to reapply immediately after swimming or sweating.
3. After using towels: Towel drying can remove sunscreen from the skin, so it’s important to reapply your natural mineral sunscreen after your child has been towel-dried, even if it hasn’t been two hours since the last application.
4. During peak sun hours: If your child is spending time outdoors during peak sun hours (between 10 am and 2 pm), dermatologists advise reapplying sunscreen every hour or so as the sun’s rays are the strongest and most damaging during this time.

Now that you have all the info, it’s time to find the best non-toxic sunscreen for kids and the safest sunscreen for babies.
