That's an interesting news story on the site today about skin cancer and being extra careful about your lips, since lip gloss can attract dangerous rays that can cause skin cancer.
I just want to add that ears are often neglected too. I've often been careful about lathering the sunscreen on my face, neck and arms, but totally forget about my ears. Also, the part in my hair has been sunburned several times because I forget about that too.
Now I'm careful to wear a really good, wide-brimmed hat.
