Sunscreens
Friday, August 1st, 2008I love commenting on the New York Times. That is where so many people get their health care information. Yesterday, they had a big picture of a sunburned young woman, and a long article about sunscreens. Sunburns increase the risk for skin cancer. Sun rays cause pigment, wrinkles and premature aging of the skin as well as skin cancer.
Sunscreens can be so confusing. We often see burns even when people are using sunscreens and here are where we find the pitfalls–
1. expired sunscreens-make sure your sunscreen is up to date
2. lack of reapplication-make sure you reapply every 2 hours, or more if in the water or wind or sweating
3. not using enough-apply liberally-grease it up! most people only put on a tiny bit, which doesn’t work well.
Other sunscreen advice–make sure its broad spectrum UVA/UVB coverage and at least an SPF 30 or higher for summertime use. There is a smaller difference between 30 and 45 than between 15 and 30, but the higher you go, the better the protection, as long as it is a good quality sunscreen. Look for good ingredients such as Mexoryl, Titanium Dioxide, Zinc Oxide or Parsol 1789/Avobenzone.
I find many people burn with spray sunscreens-not sure why. Either the sunscreens don’t work as well, or people don’t apply them properly. Personally, I stay away from the sprays. On hairy surfaces, people sometimes like gel based sunscreens better. Those are fine, but they don’t last in the water as well. Also, anything that says waterproof or sweatproof is not correct. There is no such thing as waterproof or sweatproof. All sunscreens need to be reapplied.
Sun safety also includes- seeking shade, wearing a hat preferably with a broad brim since a baseball cap only shields the upper face, wearing protective clothing, and trying to stay out of the brightest rays from 10-4 if possible.
Enjoy your summer!
