Here's a familiar story. As soon as I started seeing reviews of this foundation, I was quite certain I needed to try it out. When I went to a counter and got colour matched, there was no going back. The shade (Porcelain 012) is perfect if you've very pale Irish skin like myself and Sinéad (nine times out of ten, we take the same shade in foundations).
A little more about Dior Star itself (don't you just love the name?!) - it's billed as a brightening, diffusing foundation that neutralises any colour imbalance. On counter, you'll see that it's labelled as a light-medium coverage formula, but I'd argue that it can be built up. The finish is a satin - very similar to Make Up For Ever's HD but a little more brightening and creamy.
I love that this isn't a mattifying foundation but my oily skin still gets on very well with it. It's extremely comfortable to wear and doesn't feel at all heavy, even when I layer it up. For application, I find that a buffing brush like the Real Techniques one works best - although I am eager to finally get my hands on a Beauty Blender and give it a go with this as well. The formula absolutely melts into the skin and leaves a really perfected finish - it won't cover everything in the manner of, say, Laura Mercier Silk Creme, but I just go in with a good concealer afterwards to remedy this.
I feel that Star does everything that Dior claim it does. It is beautifully brightening and perfecting, feels weightless, and definitely qualifies as studio makeup as it photographs well - although I've yet to test it with flash. The formula is so fine that it is very hard to even detect on the skin once blended properly. There is an SPF of 30, too - high for a foundation and handy to have. This is a perfect winter foundation, especially if your skin is dehydrated, as it's so comfortable to wear. The wear time isn't as long as what I'm used to but can be prolonged with a good primer - plus, this looks so good on and I just love it so much that I really don't care if I have to make it work a bit harder to last.
If you've been thinking of trying this, don't hesitate. I have a lot of bases in my collection but nothing quite like this - it's a really modern formula that would suit a myriad of skin types.
