What does SPF measure?

The sun has two types of harmful ultraviolet (UV) rays, both of which can cause skin damage. These two types are called UVA and UVB. SPF measures how well your skin is protected from sunburn, which is primarily caused by UVB rays.

Do I need Broad Spectrum?

Since UVA and UVB rays can both contribute to skin cancer and long‐term visible signs of damage, it's very important to choose a Broad Spectrum sunscreen offering protection from both types of rays.

What do the different SPF numbers mean?

An SPF number is directly proportional to the sunburn protection level provided.

What SPF is best for me?

Dermatologists recommend a Broad Spectrum of at least SPF 30 to provide daily protection from the sun's harmful UVB and UVA rays.

Who should use a high SPF sunscreen (higher than 50)?

While dermatologists recommend using Broad Spectrum SPF 30 for daily protection, there are some situations where Broad Spectrum SPF levels higher than 50 may be advised:

Under-Application

Who Should Use an SPF 50 and Above

Most people apply only 25% ‐ 50% of the recommended amount of sunscreen—and a smaller amount can lead to SPF levels much lower than label indicates. A higher Broad Spectrum SPF can provide a margin of safety in case of under‐application.

Protection Over Time

Who Should Use an SPF 50 and Above

Exposure to the sun's harmful UV rays can add up all year long—not just in the summer! This means sun damage is accumulating over time. A Broad Spectrum sunscreen with high SPF will better protect your skin over time from accumulated damage.

Remember, no matter what Broad Spectrum SPF you choose, it's vital to reapply frequently, apply enough, and keep out of the sun when you can. Get more expert sun protection tips here!
