Patricia Lejeune uses MAC makeup, Anna Wascar uses MAC makeup - in fact, I would say that 99.99% of all independent makeup artists on the planet use MAC.
All I know is, my airbrush makeup didn't rub off when I touched it so I had no need to touch it up. And this is a big deal for me because I do not like putting new makeup on top of old makeup
In the end, I think it comes down to personal taste. I wanted a natural look, and there is NO liquid foundation on the market that is light enough for my freaky complexion. So for me, the subtle, flawless, sheer-feeling coverage of airbrush makeup was ideal. I also wanted a natural look with my color cosmetics, but that's just me! Everybody likes a different look, and thank goodness there are so many choices in the Orlando area.
