Thumbs up for overall safety & sensitivity. Still important to consult with your doctor.
Our Baby Sunscreen formula was designed with sensitive skin in mind and made without using synthetic fragrances, dyes, or parabens.
Non-nano zinc reflects UVA and UVB rays from the surface of our skin.
The SPF (Sun Protection Factor) on a bottle of sunscreen indicates the level of protection we're getting from the sun's UVB rays—which are the sun rays most commonly responsible for sunburns and skin cancer.
SPF, which stands for Sun Protection Factor, has been used for decades to determine the level of protection someone can expect from the sunscreen they use. It can often vary from person to person given multiple factors such as testing methods and environmental factors. In addition, everyone’s skin is different, which can also affect what kind of SPF is best suited to fit their individual needs.
A common misperception is that the SPF number on a bottle signifies the amount of time you can spend in the sun without getting burned (30 minutes for SPF 30, 50 minutes for SPF 50 etc.) This is not accurate. In fact, the SPF rating system is far more complex and based on the degree to which a certain formula protects against the sun’s harmful UVB rays over a certain period of time. For example, a sunscreen with a rating of SPF 30 allows only 3 photons per 100 to penetrate the skin, meaning it shields approximately 97% of the sun’s harmful UVB rays. This roughly translates to 30 times the protection you’d have versus using no sunscreen at all. This extends to SPF 50 (98% or 50 times the protection) and SPF 70 (98.5% or 70 times the protection). The length of time that a sunscreen will protect you from sunburn will vary based on the UV index at the time as well as other factors.
At Sun Bum, we like to think we make sun care products for everyone. So, whether your SPF preference is 30 or 50, mineral or non-mineral, lotion or spray, you can stay protected from the sun’s harmful rays. As noted by the Skin Cancer Foundation, “The best sunscreen is the one you’ll use.”
Global SPF assessment standards have been updated several times over the years, with the most recent update in 2019. The purpose of these updates—which were led by regional regulators and groups such as the International Organization for Standardization (ISO)—was to reduce the variability of SPF assessments. Currently, even the globally recognized “gold standard” SPF test — the in-vivo test known as SPF ISO-24444 — is subject to considerable variability due to the inherent human biases built into the testing process (Ruvolo, Yousefian,International Journal of Cosmetic Science, Dec. 2025). Because of this, there is an increasing call for governments and regulators to update the testing protocols and standards they recommend for manufacturers to follow — for example, using the HDRS-ISO 23698 test: an in vivo/in vitro hybrid that addresses some of the more subjective factors common with in-vivo only testing. (Ruvolo, Yousefian,International Journal of Cosmetic Science, Dec. 2025).
Avoid making a rookie mistake! Reapply every 2 hours and after swimming, sweating and toweling off.
Yup, 90% of UV rays still find their way through clouds, which means you can still get fried.
We know it’s tough, but try to limit sun exposure when the sun’s rays are most intense (10am to 4pm).
Yep. Reflections off water and snow can increase sun exposure by up to 50%. Keep that in mind when you’re surfing or on the slopes.
Keep newborns out of direct sunlight and always cover them with shade. Check with your pediatrician, before applying sunscreen to children under 6 months.

"I love this product because it checks all of the boxes. It’s a spray on lotion that is easy to apply. It has a high SPF factor of 50. It’s a mineral formula, which is what my dermatologist recommended. It comes in a handy, TSA approved bottle."
"Works so well on my boys. They both have sensitive skin and so far this has worked great!"
"Got this for my 2. 5 year old, thinking it would be good to spray it on her scalp when she wears pigtails. So far I've ended up using it on her face, and if I spray it into my hand first it feels like not that much makes it onto her? But if I get my technique down, I think this will be a good addition to our sunscreen arsenal. It's a convenient size to tote with us, and rubs in well."
"I love the idea of this product, took it to Disneyland. I don't know if there was something wrong with my sprayer on the bottle I had, but every time I sprayed it, it went everywhere that I didn't want it to go, on my friend's sunglasses, allover the stroller, etc. Which the sprayer worked better."
"These are my go to sunscreen for the kids. Easy to apply with the spray nozzle."
"A mineral sunscreen that actually rubs in!! I’m thrilled. The application is nice, so is the scent and the fact that it doesn’t leave your skin with an obvious white layer like most mineral sunscreens."
"not too much of a white cast. works great. I like the spray on the Mist better but it might not be an option for this product"
"Love ❤️ love love it!!"
"I absolutely love this sun screen. It is easy to smooth into your skin. You can see where you have coverage with a slight white tint. Highly recommend."
"This sunscreen is amazing. It’s silky without being greasy. Great company and product."
