Allow me to get up on my soapbox for a minute.
I had a dear friend die from malignant melanoma. He was a very active guy. He was a marathoner, a triathlete and did ride and ties. He was a high school teacher and track coach. His death was not pretty - the cancer totally ravaged his body and in the last days of his life, he became blind and then could not recognize his family. He left behind a wife and three daughters. He was in his 40s.
The one thing that came from his death is that EVERYONE in our circle of friends, even the guys, are now everyday users of sunscreen.
For women, it's not that difficult to do sunscreen on your face daily. Just replace your daily moisturizer with one with at least SPF15. There are many excellent ones out there now, from very lightweight ones to heavier ones for those of us who need extra moisturizing. For a guy, it's a little more of an effort to get them to add a daily moisturizer to their routine - it's still a "girly" thing. But, if you can convince them that their skin is more smooth and sexy to you (it feels so nice to touch a soft skin!!!), they might get into it easier. When you are going to be spending time outdoors, up your sunscreen from your moisturizer to pure sunscreen. All over your face, ears, and exposed body, 30 minutes before you go out!! If you aren't wearing a hat, use some of the spray sunscreens that are now available for your head. Worried about yucky hair - which is worse: bad hair or cancer??? It doesn't matter what your skin type is - you need sunscreen!!
I worked all winter outdoors at my ski resort. On the very sunny days, I used Neutrogena Age Shield 70+. On snow days or cloudy days, I used Neutrogena Ultra 45+. I got some tan, but not the "hey I work at a ski area/goggle face" tan that others got. In the summer, I use Aloe Gator 40+ on the arms, legs, and "decollete"when I go outdoors. Works for me, whether I'm biking, golfing, bodysurfing, or just hanging out.
Thanks for allowing me to speak out. Off my soapbox.
