I've been spending a lot more time cycling in the sun than ever before. I don't mind slathering sunblock on my arms, neck, etc., but I don't like that greasy-faced feeling of putting any quantity on my face. So this weekend, having ridden several hours on two beautiful sunny days, I didn't like the redness in my face when I looking in a mirror. I've had a couple of basal cell thingies removed in the past and would like to be cautious given my general history of skin disorders.
So what type of sunblock is particularly good for use on your face? I remember using a gel-type product a few years ago called (IIRC) "Shade", but don't remember how effective it was.
Also, what about getting sun on a balding pate through the helmet vents? I have a fabric helmet liner that would cover my head, but in the summer it counteracts the reason for the vents in the first place and just makes my head super-sweaty.
