For a full face paint I'd use professional (theatrical use) water paint and translucent powder. Never noticed any cracking provided it's not applied too thickly. I have thin, sensitive skin and grease paint starts to itch within minutes, even if it's just half a cheek covered by it.
I'd try out several brands and give them a trial run to see what works best. The water paint I used (Leichner brand) was rather inexpensive and worked very well with different designs.
