Sunscreen is important to help protect your skin from the harmful rays of the sun. When used correctly, it can help decrease your risk of getting skin cancers, as well as help prevent premature skin aging if used as directed with other sun protection measures. This includes wrinkles and skin discolorations caused by exposure to the sun.

There are multiple types of rays that the sun emits. The two that can impact your skin the most are UVA and UVB rays. The easy way to remember the difference between the two is to think of UVA rays as the ones that can contribute to premature skin aging. UVA rays are the ones that can give you more wrinkles and skin
discolorations.

Think of UVB rays as the ones that contribute to the sunburns you can get from too much sun exposure. The UVB rays are the ones that can increase your risk of getting skin cancer. Choosing a sunscreen that is broad-spectrum SPF means that it will help protect your skin against both types of rays—UVA and UVB.
