It’s the stuff we use every day. It’s the sunscreen formula that started it all. People say it smells like summer®. We like that.
The sunscreen formula that started it all
Helps shield against harmful UVA/UVB rays
Stays on through sweat and water for up to 80 minutes
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.

"Great product, promotes a safe tan with no burning (I do tan fairly easily, though). Spray goes on evenly and the scent is nice, too."
"Thank you for answering all my questions."

"My favorite sunscreen! It has great coverage, great protection, smells great, and it doesn’t irritate my skin! Got a travel size for vacation!"
"This is my first time buying the spray. It has great coverage and was super easy to use on the beach without getting sand mixed in with a lotion."
"Tried the Premium Moister Spray Sunscreen 50 SPF Let's start the positives: Smell ~ Great tropical smell. Really enjoyed!! Application ~ Very easy to use. Top of canister contains a push style sprayer. You can turn the sprayer to lock to prevent unwanted spraying. Performance ~ Sun Bum Delivered! Was out in the sun for 5+ hours today with temperatures reaching 100+ degrees. Applied spray at the beginning of the day and did not need to reapply. Unfortunately we need to share the negatives as well: Texture/Feeling: I was not a fan of how the products stayed on the top of my skin making it feel very greasy. As dust and dirt was blowing around in the air, it felt like it was sticking to the sunscreen. Personal Preference: As a personal preference, this is not a use again product for me. Was really too greasy for my liking."
