Every summer we get bombarded with sunscreen ads, and going to the store can be overwhelming with all the different numbers and ratings. So, we are here to help narrow your options and break down the facts of SPF for you.

Many people don’t know there are actually two types of Sun Protection Factors (SPF); Physical and Chemical. Physical SPF works by deflecting the sun’s rays and includes anything you can wear or use to protect your skin. These include items like clothing, hats, sunglasses and umbrellas. Chemical SPF is different as they are ingredients found in sunscreens and lotions. These ingredients work to absorb the sun’s ray instead of deflecting like Physicals.

When using Chemical SPF, choose one with at least 30 SPF or higher. Be sure it states that it is broad spectrum. Broad spectrum means that the product will protect against both UVA and UVB rays. For best use, apply the sunscreen or lotion at least 15 minutes prior to going outdoors, reapplying every two hours, especially after swimming or sweating. Make sure all skin not covered by clothing is protected with sunscreen. If you are relying solely on sunscreen for protection, using a super high SPF, like 100, is a good option. We, however recommend to combine both clothing and sunscreen as a way to best protect your skin.

The science behind SPF is complicated, but your usage of it doesn’t have to be. Just be sure to use both Physical and Chemical methods in conjunction with each other for maximum protection from the sun’s rays. Prolonged exposure to the sun can cause irreversible damage.
