FAQ about sun protection

How long before sun exposure should you apply sunscreen?

It is generally recommended to apply sunscreen About 30 minutes before sun exposure due to how sun protection products are tested. Protocols require 15 to 20 minutes of drying time before assessing sun protection factor to ensure water resistance, but no evidence suggests that sunscreen efficacy is delayed.

How often should you reapply sunscreen during the day?

It depends on the activity. For prolonged exposure at a pool or beach, reapply the sunscreen every two hours. For a commute from home to the office, one morning application is sufficient.

Does SPF protect against UVA rays?

The SPF measures a sunscreen’s ability to filter erythemal UV rays, which consist of 85% UVB and 15% UVA.

After several days of exposure, is it possible to reduce the applied SPF?

According to some studies, applying sunscreen for several consecutive days before UV exposure may provide a baseline level of protection for the skin. This could suggest it is possible to use an SPF 30 product after several days of SPF 50 use. However, research on this topic remains insufficient, and as a precaution, we recommend continuing to use a high SPF throughout the exposure period.

Are tinted SPF products sufficient to protect the skin?

Tinted formulas with SPF provide additional protection. Alone they do not provide complete, long-lasting sun protection because they are not applied in sufficient quantity.

Should you apply sun protection in winter?
