Is there such a thing as gender bias sunscreen? A sunscreen that works better on males than females? Hmmm… I’d like to take a pole to see how many men wear sunscreen on a daily basis. Probably not that many but quite a few new men’s grooming lines are cropping up every year so there has to be a demand. From a line that's been around for a long time and will conquer your man’s sun issues is JACK BLACK's Sun Guard Oil-Free Very Water/Sweat Resistant Sunscreen SPF30 ($16/4oz @ dermstore.com) from the Black Diamond Formula Sun Protection collection. It’s oil-free and like the name conveys, contains the new FDA approved sunscreen/anti-aging ingredient Parsol 1789, and made for very extreme conditions. I’m thinking Mohave dessert extreme. They claim the SPF will last 80 minutes after your mate has come out of the water. I would have loved to see that focus group experiment! So, like his deodorant and razor, I will be coveting this one too.
