I was skeptical about this foundation's staying power because it is VERY thin and runny. That said, once applied with the GA Blender Brush (which I highly recommend for applying this, it does not blend well with fingers and is too fluid to use with a sponge) the foundation sets and lasts a full 8 hours even on oily skin. The colour does not oxidize or transfer onto clothing, and the finish is sort of a satin-matte (matte with a bit of a natural sheen - no glitter). The coverage is medium and buildable to full with two to three layers on problem areas, which is good if you need full coverage in certain areas but don't want to put on a full mask all over your face. I have used this foundation almost daily for over 4 years, including 1 year in India and it is the only liquid foundation that I have found to last in a day of heat and humidity!
I bought a bottle of this years ago to support a friend of mine who was working the Armani makeup counter, and I've been hooked ever since! Have tried others, but keep coming back to this. The texture is so light and stays on.
