This really is a great powder foundation, especially for the price. I haven't tried MAC Studio Fix personally, but so many people have said that this is a great dupe for it.
My favourite thing about this powder is the fact that it has amazing, buildable coverage that is so non-cakey in finish - something that is often not the case even in quite sheer coverage powders. Obviously you can use this as a foundation on its own, or you can use it (lightly, or I find that it can start to look a bit obvious) over foundation to set it and add some extra coverage. I personally like using it with just a bit of concealer, for a really nice, "flawless" yet everyday base.
The only downside with this powder for me is that the shade selection is very limited - three shades, whcih are all fairly similar - nothing super dark or super light. I found that the lightest shade for me was just slightly too pinky-based to work perfectly on my very fair, warm skin. Obviously I could make it work, by blending it out really well, but it did mean that it wasn't quite as quick and convenient as I had hoped.
Overall: I'd definitely recommend - it's amazing quality for an amazing price! Just be aware that if you have a very fair or dark skintone, you may have a bit of difficulty finding your perfect match. xx
Another purchase from my Melbourne trip and I got two and gave one to my sister. I have been using mine ever since and I've been loving it.
This is my current favourite powder and I haven't even bothered at my other ones. This has beaten my Bourjois Health Balance powder. This sets me makeup so well, it's not cakey and the packaging is great too as it has a mirror at the bottom with a sponge. I don't use the sponge applicator at home and I use a fluffy powder brush instead to set my makeup.
On lazy days, I just put CC cream on and this on top and it gives me a good coverage.
I don't know about the soothing and cooling qualities of this as I haven't really noticed but it does help in creating a flawless face.
