Face painting outdoors in a hot/humid place...

I am currently working in the FL Keys and just about every booking is lately is for an outdoor party. The biggest problem I am having is that as soon as the kids start sweating (which is usually immediately) I clean the skin before I start, I have a fan going to dry the paint as I work, what else can I do? Refusing outdoor parties is just not an option, I would hardly ever get an event to book. BTW- I use Snazaroo, Diamond FX and WolfeFX paints.
TIA!

starblends powders, use them as your base color and then add your details with your favorite paint, I was so please with the color brightness and how smooth it goes on, I started out with just red,white and blue for a 4th gig in over 100* heat and they save my rump I have since gotten 4 other colors and am pleased to have them cuz down here the weather can go from a pleasant 80 to 90+ humidity.

I use Starblends, but I am not crazy about the lack of coverage from the white. I have red and black too(these cover fine). I use them more on boys. Spiderman, mario, venom, etc. I do know Snaz melts quickly. I dont use snaz unless it is cooler out. You're DFX and Wolfe should hold up better. I try to stay away from the mouth (eatting purposes, kids will smear it) and if you can the most sweaty parts. (temples, neck,...) . You could always offer to paint a forearm or upper arm instead (as long as you stay out of the back of the elbow and armpit (sweat).

Hope this helps.
