The British tabloids have been running pictures of Prince Harry and Prince William at a bachelor party in London over the weekend, and the headlines all focus on their cocktail consumption and love of the "Harlem Shake."

However, this photo doesn't make me think of partying at all. It makes me think of sunscreen. And it makes me wish I could go back in time, crash the party (apparently the daytime portion involved a riverboat cruise), and slather the Prince in SPF.

Maybe that's one part responsible beauty editor fantasy, and one part every girl's fantasy. The point is, the guy needed to wear sunscreen. And if he did put some on, he needed to reapply, use a higher SPF, or both.

Not only is sunburn annoying, painful, and unattractive (yes, even on cute princes), it also causes sunspots, wrinkles, and can lead to skin cancer. Everyone should wear sunscreen every single day -- dudes and Royals included.

Knowing that guys are an especially difficult sell when it comes to SPF, I've rounded up the six best sunscreens for men -- and there's one for every type of guy. You'll probably want to pick one up for your man before his next guys' trip -- or else he'll come home as crispy as Harry.
