Take Cover: Sun Responsibly
May is Melanoma Month and I wanted to share just a few friendly tips and reminders about sun protection as we head into Memorial Day weekend.
SPF stands for Sun Protection Factor, and is used as a measure of the time it would take you to sunburn (UVB) if you were not wearing sunscreen.
Example: If it takes you 15 minutes to burn without sunscreen and you apply an SPF 15, it will take you 15 times longer to burn, or 3 hours. Choosing a higher SPF does not give you the green light to stay in the sun longer without reapplying.
According to dermatologist James M Spencer, MD, an SPF 15 blocks about 94% of UVB(burning rays) Spf 30 blocks about 97%, and an SPF 45 blocks about 98% of rays.
Be sure to look for a sunscreen that provides broad spectrum UV protection from both UVA (aging) rays and UVB (sunburn) ray. It is imperative to reapply after swimming and/or after 2 hours. Applying once is not enough for the entire day outdoors. Look for a physical sunscreen which contains titanium dioxide and/or zinc oxide for deflecting UV radiation as opposed to chemical sunscreens which only filters and tend to absorb UV radiation.
