Yes it was expensive, but lasts quite a while. 1 pump of this primer is more than enough for the face. It does leave the surface of the face amazingly smooth. Short term, it's brilliant for applying and keeping the make-up on for an extended period of time; Long term, not so good for the skin as the silicone base only smooths the face by filling up uneven bits on the face, in turn slowly suffocating it.
I only ever wear full makeup when I go out or a presentation or to do, so this base works fine, but I probably wouldn't use it on a daily basis simply because of how artificial it feels, and the thought of my poor skin being suffocated every time I use this as a primer puts it off a bit.
Also, this pump applicator isn't so great either, when it runs low it pump just gives up, but I unscrewed the whole thing and scooped the rest out and there was A LOT left on the inside, it filled 1 TheBodyShop sample pot, which probably is another 15 pumps, possibly a £4 worth of product in it. For those of you who chuck the bottle in the bin when the pump stops pumping you're probably chucking away a good proportion of your money, spend 5minutes and scoop the rest into a little pot..
It is a good primer in a sense it does it job well, but am not sure if I will buy it again as it is 1) pricey and 2) personally I feel it prevents my skin from breathing each time I use it
