@corgidad yeah, you've got to experiment a bit to find a sunscreen which stays put. I use a helmet with a peak / visor so I don't need sunscreen above my eyes but sometimes a little migrates across from my nose somehow. I eventually found a "dry active" sunscreen which doesn't seem to do that.
@nickzoic I may try using a cycling cap so it covers my forehead, so I don't have to put on sunscreen there... I was told the cycling cap also helps with stopping sweat from getting into eyes.
@corgidad they're also real good if you're not too hirsute on top and might otherwise end up with you head covered by an array of weird vent-hole shaped sunburns.
