No matter what type of setting powder I use I always get shine after a few minutes of use. If I'm not planning on going anywhere important I'll use the NYC transparent setting powder but it doesn't really do much of anything. After about a half an hour it wears off. For the price, though (around 3.99 for a large container) it's not bad for casual days or days when you aren't wearing foundation. The best setting powder I've found so far is the Mattify! Ultra loose powder. It's meant for very oily skin which I have but, just like any other powder I've tried it wears off after few hours AND I have to order it online.
Now for the NYX powder....MY SEARCH ENDS HERE!!!!!!!! This is by far the best powder I've used hands down. I apply it in the morning and it lasts all day. My face stays pretty matte until the end of the day when my skin looked dewy instead of the normal oil slick and that's after being out all day and spending my fair amount of time in the Florida sun. I think if you're looking for something that is truly going to keep the oilies away and not break you out give this powder a try.
*the only drawback to using this powder is the container but I think that's a problem with most loose powders. This one is very finely milled so almost no matter what the powder tends to blow away as soon as I open the container but I'll take that considering the powder is a miracle worker.
I've owned a couple high end finishing powders and none even come close to the NYX HD Studio Finishing Powder. It leaves your face completely matte and takes away all shine/oil. I find it also gives my face a lovely smooth look, like I've been airbrushed. I also found that unlike my high end finishing powders, the NYX last all day. I hardly ever have to re-apply it. The only downside is I wish it came in better packaging. Because it is so finely milled, it easy to spill it or use to much. To apply, I turn it upside down (making sure the lid is closed on tight first) and give it a small shake to allow the power to go onto the inside of the lid, then I turn it back over, tap the lid lightly and then open it. I use a Large Mac face brush, using only the powder still left on the inside of the lid to do my whole face. If you dip your brush in the powder itself you will most certainly get too much on your brush. You can't beat the price either!! Great product!!
I have both of the other well-known silica setting powders, the MUFE and Elf versions. I actually prefer this one over both. It seems to be more finely milled and smoother, so finely milled in fact, that it drifts up into the air when the lid is removed. Annoying, yes, but this is just an indicator of how very fine the particles are. As such it doesn't cake or settle into fine lines, nor does it emphasize dry patches. Just a very smooth and beautiful finish. It's 100% silica, and I don't remember how that compares to the MUFE and Elf, but I'll check the label and update. The only reason I'm giving it a '4' is because the very small amount in the jar makes it deceivingly expensive at $9.99 US (Ulta).
I don't mind this powder it's great for setting lipstick aswell. Pat lips with tissue add powder and then more lipstick - nyx haut melon of course ;o) I have heard you can use corn starch as a translucent setting powder but pure silica works well too.
Another inexpensive, winning product from NYX. It's 100% silica, and honestly, I don't have another powder of its type to compare to, but I really like this one.
Goes on nice and smooth with a fluffy powder brush, gives a nice finish (seems to hide pores very well).
Only complaint is the packaging. I wish that instead of a flimsy plastic film covering the holes that dispense the loose powder, it was a sturdier plastic thing that could actually control the flow of powder better.
