Chemical sunscreens use one or more chemicals including oxybenzone, avobenzone, octisalate, octocrylene, homosalate and octinoxate.

 

The SPF refers to the ability of a sunscreen to block UVB rays that can cause sunburns, as well as UVA rays, that can cause deeper skin damage.

 

Sunscreens will remain potent for up to 3 yrs per FDA regulations, most include expiration dates. Just make sure to check the formula and smell before you use it to ensure it is still good to use.

Reapply sunscreen approximately every two hours, or after swimming or sweating, according to the directions on the bottle.

 

Avoid sun exposure, especially during the hours of 10 a.m. and 4 p.m., when UV rays are strongest.
