How can I protect my skin from the sun and use sunscreen correctly?
Combine shade and protective clothing with broad-spectrum sunscreen rated SPF 30 or higher, choosing water resistance when needed. Reapply outdoors about every two hours and after swimming or sweating as instructed. Sunscreen does not make unlimited sun exposure safe.

Cover commonly missed areas
Apply enough to exposed skin, including ears, neck, backs of hands and exposed feet. Follow the product timing and directions rather than relying on a thin layer or a cosmetic that misses exposed areas.
Protection is more than a cream
Use shade, hats, clothing and protective sunglasses, especially when ultraviolet exposure is high. Darker skin also needs protection. Tanning oils are not a substitute for sunscreen, and tanning beds should be avoided.
Choose a tolerable product
If a sunscreen irritates your skin, discuss an alternative with a pharmacist or clinician. No single formulation suits everyone. Maintain protection on cloudy days and during outdoor activities. Not developing sunburn does not mean there has been no ultraviolet damage. Water-resistant products still need reapplication according to their label.
