Is SPF 20 better than nothing?

SPF 20 is better than nothing, but it is not the best protection against the sun’s harmful UV rays. The American Academy of Dermatology recommends using a sunscreen of SPF 30 or higher for the best protection. SPF 20 blocks about 95% of the sun’s UVB rays, but SPF 30 blocks 97% of the UVB rays. It’s important to remember that even with SPF 20, you should still reapply sunscreen every two hours, or after swimming or sweating.

Is SPF 20 good enough?

SPF 20 is considered a low level of sun protection, and is usually not recommended for people who will be spending a significant amount of time in the sun. SPF 15 is the minimum recommended level of sun protection, and higher SPF levels are even better. It is also important to remember that sunscreen should be applied liberally and often, even if it has an SPF value of 20 or higher.

What does SPF 20 mean?

SPF 20 is a measure of the amount of UVB protection a sunscreen provides. SPF stands for Sun Protection Factor and is a measure of how long a sunscreen will protect the skin from UVB rays. SPF 20 offers medium protection and is suitable for normal, everyday activities. It is important to remember that SPF ratings only measure the protection from UVB rays and not UVA rays, so it is important to choose a sunscreen that also offers UVA protection.
