A Shot Glass of Sunscreen

By Dr. Susan Van Dyke
March 26, 2010

I am sitting here watching the Today Show, waiting to go on air live on AM Arizona to talk about summer skin. It may not been a national audience but so what, I just love to reach people and share what I have learned in 24 years of dermatology practice (the last 15 limited to the fascinating field of cosmetic derm).

So what have I learned?
-A shot glass is a good way to measure your sunscreen (a full ounce is the right amount to cover the average body for full effect).
-If you just won’t go for that much lotion reach for the super high SPF. Half an ounce of SPF 50 can stand in for an ounce of 25 if spread evenly.
-UVA coverage is important, broad spectrum is the right thing to look for on the label.
-Many UVA sunscreen ingredients degrade over a few hours after application, you must reapply even if you don’t sweat!
-Helioplex is the exception, it is pretty stable and lasts much longer after application.
-Tanning beds are not the answer, they give out lots of UVA which does promote wrinkles and skin cancer only without the burn.
-Best lesson of all- the color you are born with is the most beautiful color of all, protect it!
Got to go, AM Arizona is ready for me.
