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.
