If I use face paint and not a mask I like this stuff: Buy Natural Camo Paint - Camouflage Face Paints | Natural Camo
Not greasy, scent free, sweat proof, easy on with roller applicator which I really like, and easy off with baby wipe or plain soap and water.
Carbomask is great. It's clay-based so it dries on your face.....no grease. Works great as a sunscreen as well when I'm roaming around in the bright sun at high altitude all day. I forget I even have it on, and usually forget to wash it off.
Big neck gaiter fan here. I tried the paint, but didn't care much for it. The neck gaiter is always right there- can let it bunch under the chin when warm, and a quick pull over the nose when time.
I've tried several other brands, one a multi colored stick. Hated the greasy feeling, smell/aroma of crayon or sticky feeling and that comes off if rubbed slightly by gloves or fingers to scratch an itch.
Hardy is it for me. Not greasy, no irritation, no smell and you cant even tell its on your face...unless looking into a mirror.
