Activity for Samantha

I've heard great things about airbrushed make up but I've never seen or used it. What's good about it and bad about it? Are there any skin types it's not good for? Also is it expensive/does anyone know anywhere in the Philadelphia/Bensalem PA area...

I just signed up and I'm using the iPhone app and I don't know if I just don't know what in doing or if its just very limited compaired to the full website...?
