I've been using this for about a month now, but it hasn't worked well for me. I'd been using the Body Shop all-in-one face base for a while, but since the summer weather I'd felt I wanted to wear something lighter and a bit more dewy rather than matte. This mineral foundation promised a natural no-makeup look, which is what I wanted. Unfortunately I have to admit that it's been a disaster in every way, and today I went back to using the face base and already look ten times better than when I used the minerals foundation. Firstly, and most obviously, I have combination skin, but this powder turns my whole face into an oil slick within the first hour of wear. I'd be wanting to wash my face all the time because it felt so dirty with this product on it after only a couple of hours. With the face base, this doesn't happen - the worst I'd get is a bit of shine on my nose which could be easily sorted with another application as it comes in a compact. The minerals foundation has terrible packaging and always results in a mess all over me and the bathroom after each application. It is not suitable for touch ups. So that would leave me wanting to mattify with the face base, but the face base is so starkly matte in contrast with the minerals powder, that this would look a bit odd.
The other issue is the colour matching - in store the golden ivory shade seemed to match my skin perfectly (pale but with a summer glow). However after a day of wearing this shade alone I noticed that my face seemed darker than my neck, which made it look dirty. So I (foolishly/desperately) purchased the lightest shade to try mixing the two - there seems to be a wide gap between the lightest shade and the next one up, as the lightest is almost ghostly pale and quite pink rather than yellow toned as the others seem to be. Mixing helped (or so I thought), but I still noticed a difference between my face and neck colour after a few hours of wear, so can only assume the product is oxidising and going darker on my skin.
I purchased the foundation on a promotion price. It's still a waste of money at the reduced price, but the full price is a big rip off considering how small an amount of product you get, quite apart from the poor performance.
It doesn't cover blemishes at all, but this didn't concern me as I am happy to use a concealer with my foundation as I don't like foundation to be too heavy, I just want an evening out of my skin tone. The minerals powder seemed to fit the bill upon first application, but after sitting on my skin for any length of time, it only makes me look worse.
