ProAiir ProLong is three products in one. 1) Barrier spray, 2) extender of any PraAiir product without effecting pigment (like a thinner) and 3) Mixing liquid for your mica or glitter powders. ProLong is an extender/barrier liquid to help makeup last longer on sweaty actors. ProLong also rehydrates ProAiir makeup without effecting pigment, which also helps a smoother airbrush flow.
Even protect your water base makeup under but Allow to dry before touching. When applying with sponge, dab on only as rubbing will rub off the underlying makeup. Set with baby powder or translucent makeup powders. When used over water base makeup it helps reduce smudging. Not tested on animals but does contain shellac which is a byproduct of bees.
Remove with liquid soap first - rinse with water after.
