So im doing a Cait Sith Gijinka version and i will have to use face paints on the whole face and neck area

and im wondering what is the best type to use and how to stop it rubbing/melting off during the con

i will be using black and white and dont realy want them to run into each other

so any help with be rewarded with hugs

I bought some face/bodypaints recently and the costume shop employee suggested a special sort of fixing spray. I don't know what it's called in English, but she said it would prevent smudging and make the paint more water resistant.

i was doing a quick search and yep its like a setting spray which fixes the paint I would buy it from the internet purely because i wouldnt know where to get it in a shop. I guess you could try fancy dress shops ?

hope i helped

I asked about paints for cosplay as my friend is cosplaying Gene Starwind from Outlaw Star, who has tattoos and scars and such.

Snazaroo face/body paint is the one which was highly recommended to me, as was Grimas.

I'm not sure about brands, but applying talcon powder on the white sections (I don't know what it does to other colours) will absorb the moisture from your skin if you sweat, and will stop the paint from running. I usually apply some more every 3-4 hours, though it's really just personal preference.

Snazaroo is the best way to go. I used it for both my Emily and Little Sister cosplays, it does rub off on friction areas such as where your clothing meets your body but nothing will stop that unless you latex yourself. Obviously an extreme you don't want to go to.
If it's mainly your face I wouldn't worry about sweating it off as the paint dries out your skin. Be very warey to stay hydrated though, if you're in a costume that's not easy to get out of for toilet trips then drink powerade or another form of sports drink and have eyedrops with you if you wear contact lenses. Dried out eyes plus lenses lead to an irritated cosplayer!!
