How do you do caveman makeup?

start by doing some shading under the eyes and maybe some darker shade on the eyelids. Also creating a unibrow gives a good caveperson effect. If you still want more, adding some bizzare "war paint" (a red stripe down the nose, blue spots on the cheeks) which makes it look nice and tribal too.

We have caveman prosthetics and kits if you want to go for a more realistic looking caveman. www.fxwarehouse.net
