Pro
- I liked the fact that they included the two different applicators

Con
-Did not control the oil on my skin
-Hard to apply because the fan brush left streaks and the sponge left odd patches
-It caked up after 1/2 an hour
-Some of the powder can fall out because the bottom of the compact has little holes.
-Price was a bit expensive
-The mirror became dirty easily

Bought this on a trip to a much hotter climate and needed something to keep shine and oil to a minimum. I have to say, this is one of the best powders I've used. It's very finely milled and completely natural looking match for my summer tan ( I bought 'All the World's a Stage' beige). It feels light and comes with a 15 spf rating as well so it seemed like my hg. But after maybe a day of using it I started to break out terribly! I've been blessed with good skin so it was really strange to just break out, all over- the reason why this didn't get five lippies. But I don't know if it was the climate change or the powder so I'll just wait and see.
This is overall, a great product so I hope it's not the cause of my skin problems... : /
Update: No, it was definitely the powder doing all that damage. I blame the oxybenzone- Should've checked the ingredients. One lippie.

Great powder! It is lightweight and truly does hide flaws. However, it doesn't seem to last as long as other powders I've tried. Make sure you bring it with you so you can keep reapplying all day. Would definately purchase again.

i was a bare minerals girl, but i felt i wasn't getting the best coverage for my oily, acne prone, sometimes reddish face. i picked up this foundation at sephora in desperation and was skeptical that it would work. i thought it might look 'fake' and make me break out - two of my biggest fears with any foundation. also panicked when i opened it because i thought it did not come with an applicator..well, i have been using this for 3 weeks and i could NOT be happier. It even conceals my under-eye dark circles and stays put all day.
(and does NOT clog my pores...YAY!!!) i love it!!!

No oil control at all, it wears pretty well and looks natural. However my face greased up 2 hours after application. Not what I'm looking for in a powder foundation.

Packaging is cute

I used Hello Flawless! in Champagne I believe. It's a great powder, very soft and finely milled. I love that you can use a sponge for medium to full coverage and the brush for touchups or sheer to light coverage. It didn't cause any breakouts on my skin and kept my face relatively matte as well while looking pretty natural.

But now the downside: the reason I won't be buying it anymore is that it runs out too quickly. Also the brush they provide is not the best; the bristles are pretty stiff and it adds to the accelerated use of the powder by creating too much excess. So while the product itself is great, I didn't much care for the execution.

It lives up to its name, that's for sure! My skin has never looked smoother than when I first apply a thin coat of Hello Flawless.

I'm pretty pale, and "Me, Vain?" Champagne has the right tone for me for summer, ever so slightly darker than my normal complexion, but not so that I get the dreaded orange line at the edge of my face (oh, it blends well, too!), just so that I look a little more lively and my blemishes are evened out better.

Holds up decently to hot Texas summers, if not perfectly. At the least, I don't get clumpy runs of powder if I sweat a bit, and it wears evenly so it's no more or less noticeable as I heat up. Doesn't clog pores, either, which is a huge issue for me!

As others have mentioned, the packaging is cumbersome in relation to the contents, making it too big for my regular makeup bag — though I do love the big mirror and I'm fine with the sponge for heavier application. I use a foundation brush instead of the included one, though. And the price is far higher than I'm used to, but I don't feel ripped off.

Gram for gram, this powder is more expensive than MAC's Select Sheer (NC 40 is closest to Benefit's Beige, which I use). But it comes with a brush and a sponge, making it easy for touch-ups and full coverage. The Flawless goes on more opaque than Select Sheer, so I'd recommend it for those who have something to hide.
I like that it stays true and doesn't oxidise, as some powders tend to do. It lasts all day on the cheeks, but in my oily T zone, I need a touch up after about four hours. But I live in the tropics where EVERYTHING streaks when you're outdoors.
I don't know if I'll repurchase, though. The MAC does it all for less money. Benefit's clever retro packaging is fun, but ultimately it's just window dressing.

I'm not a huge fan of foundation in powder form but for some reason I love this stuff. I do sponge on the powder very quickly if I'm running out the door. If I want a full coverage I usually put my liquid foundation on first and then this powder over it to set it. It worked like a charm and lasted a very long night of Vegas partying (which we all know can be very hard to do) I didn't touch up once. The only issue I have with this powder is how little product you get. I don't use very much of it, and it lasted me a good 4 months before I had to buy a new one. I'll still continue to buy it because it's the only thing that really sets my liquid foundation.

I switched to this from MAC's Mineralize Skinfinish because as the summer was approaching, my complextion became darker. I wanted to try something different, and this was recommended to me on my Sephora beauty insider homepage, so I figured why not? It does cost more than MAC, but I imagine that's because it comes with a mirror, sponge applicator, and a brush applicator. They are both equally good powders and I would most definitely buy them again. But for right now I'm getting more use out of my Benefit purchase than my MAC.
