What's an SPF?

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.

How SPF Is Calculated and Why Does It Matter?

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.”

How Do Global Standards to Assess SPF Differ?

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).

According to the Skin Cancer Foundation, 1 in 5 Americans will get skin cancer in their lifetime. We wanna change that.

How often should I reapply?

Avoid making a rookie mistake! Reapply every 2 hours and after swimming, sweating and toweling off.

Do I need sunscreen when it’s cloudy?

Yup, 90% of UV rays still find their way through clouds, which means you can still get fried.

When should I avoid sun?

We know it’s tough, but try to limit sun exposure when the sun’s rays are most intense (10am to 4pm).

Do I need SPF in the snow and water?

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.

Does my newborn need protection too?

Keep newborns out of direct sunlight and always cover them with shade. Check with your pediatrician, before applying sunscreen to children under 6 months.

We've Got Answers

How Often Should You Apply Sunscreen Lotion?

Every 80 minutes is the sweet spot. Sunscreen breaks down over time (especially if you're swimming, sweating, or drying off), so reapplying every two hours keeps your skin protected and happy. Keep a bottle nearby—beach bag, car, backpack, whatever—so you can take your skincare and suncare to-go. Your skin will thank you.

Which Is Better, Sunscreen Lotion or Cream?

It depends on what your skin’s into. Sunscreen lotion is usually lighter, so it spreads easier and feels less sticky—great for everyday use or when you're on the go. Creams are thicker and more moisturizing, which makes them a solid pick for dry or sensitive skin. Both get the job done, so it really comes down to how your skin vibes with the texture.

How Do You Choose Sunscreen Lotion?

First up: check that it’s broad-spectrum and SPF 30 or higher. That’s your baseline. If you’ve got dry skin, look for hydrating ingredients. Sensitive? Go fragrance-free. And if you’re headed into the water, make sure it’s water-resistant. The best sunscreen is the one you’llactually want to wear—so find one that feels good on your skin and fits seamlessly into your daily scene.

Only Sun Screen I Use

Been using Sun Bum products for years. Lotion applies easily with no oily feel on the skin or overwhelming scent. Most importantly, performs as advertised and provides adequate sunscreen protection.
