What is SPF?
SPF stands for Sun Protection Factor. When you pick up a bottle of sunscreen, you will find a SPF number on the package. These numbers range from two to 50. The numbers refer to the products ability to block out the sun’s burning rays. Dermatologists strongly recommend a sunscreen with a SPF of 30 or greater for all skin types.
When should I use sunscreen?
Sunscreens should be used every day when you’re outside, not just during the summer. They can be applied under makeup and many cosmetic products also contain some type of sunscreen. Daily use of sunscreen is the primary means of protecting your skin from premature aging and skin cancer.
Just because it may not be a bright, sunny day doesn’t mean you are less likely to burn. Eighty percent of the sun’s ultraviolet rays pass through clouds. The sun also reflects on sand and snow, so wear sunscreen even if you are under an umbrella on the beach, or rolling around in the snow.
How often do I need to reapply sunscreen?
Sunscreen needs to be applied at least 15 minutes before going outside. Make sure that all areas exposed, including lips and ears, are covered. Sunscreen should be reapplied every two hours, or after swimming or sweating.
