Do lips really need sun protection? I don't protect mine but they never seem to burn.

I have to answer this one with an emphatic YES! Perhaps you could use a lip stick with an spf. That way you really don't have to ponder it. If you don't wear lipstick, then buy a lip balm that has sunscreen. There are so many great ones. And some smell and taste yummy to boot!

Juara has a good one!
