The one thing that attracted me to this particular foundation was it's SPF free formula - for both personal use and for models to build my makeup portfolio.
The ingredients in foundations containing SPF, like titanium dioxide & zinc oxide, stay on the surface of the skin and actually block UV rays from penetrating the skin which gives you the 'white mask' on flash photography. I have to say this foundation looks beautiful on camera and has a very dewy finish. I would not recommend for oily skin as you will need a lot of setting powder to keep it from sliding off your face! (Which looks terrible on flash photography by the way)
It is definitely over priced for what it is - there are other foundations around the same price range which are much better and much longer lasting - ie. armani luminous silk or mac face & body which give a similar dewy finish.
