I'm an Irish boy with red hair (ok..its arctic blonde now) and freckles. Long sleeve shirts and hats and sunglasses are always with me. Sunblocks are much better than sunscreens if you have to be in the sun. Zincofax is a sun block but, if you don't want to look like a stoner cast member from "Fast Times at Ridgemount High", I would suggest a sunblock that contains titanium dioxide. This stuff is expensive but it works. It doesn't leave the white or whatever color the surfer dudes are using now.
Pasty white is the new bronze!!
(...I thought it would look great on a billboard...guess not)
Cheers,
Mike
