Dior have a few different powder foundations but this is the 'Diorskin Forever Flawless Perfection Fusion Wear Makeup'. The name is a bit of a mouthful but it's basically the powder version of the Diorskin Forever Liquid Foundation.
I got the lightest shade which is 010 and it's a perfect match for me. I wanted it mainly to use under my eyes and around my nose for an extra bit of coverage over my liquid foundation for long days or nights out. I've only tried a few different powder foundations before but this is definitely the best to date. The texture is incredibly soft and smooth and gives a great bit of extra coverage without looking heavy or cakey whatsoever. You can really achieve a very flawless base with this worn over a liquid foundation. It also takes away shine and I definitely find it helps to minimise pores around the nose. It also contains an SPF of 25 which is nice and the compact does come with a decent sponge, although I'm missing mine.
My only criticism is that it's a bit fragile. Mine broke just from carrying it around in my handbag and I had to repress the broken pieces. It could be okay in a side pocket of your bag where it won't get rattled around though. The price of the entire compact is also very extortionate. You can buy just a refill when you run out but the price of the refill is still very expensive! The whole compact cost around €50 and I think the refills are about €40. I think the price could stop me from buying it again to be honest even though I love it! I will say, however, that I've had this almost a year and I still have quite a lot left so as a yearly purchase or less the price doesn't seem quite as bad!
