I was thinking about face paint, but I need the substance to be able to come off my skin relatively well in one or two washes without the use of harsh chemicals. While my skin is highly sensitive, it doesn't seem to be minding this nail polish so much @.@ It took a bit of looking to find a semi-quick drying nail polish or two that doesn't dye my skin red, irritates it and comes off pretty easily. Cause it quick-dries, it comes off more or less via peeling.
I wouldn't think fabric paint would work well since it's meant for a base that isn't oily. @.@ A problem with me, is that my skin's very oily and any make-up I put on I tend to smear. So unless it can dry fast and stay on pretty easily, I can't use it x_x Normal nail polish doesn't work, but quick drying seems to work for me pretty well. I wouldn't suggest it for others though unless they KNOW their skin can handle it for a good 10 hours without bad effects.
