I have fair, VERY sensitive skin. It's oily in some places, very dry in others. This product being both a cream & powder keeps my combination skin perfectly balanced. Like many people with sensitive skin, I have a graveyard of 90% full foundation containers of all shapes, formulas & brands. This is the ONLY foundation that I've ever used all of. I was debating between this & Clinique's Even Better foundation. I went with Clinique because it's supposed to be perfect for sensitive skin, being dermatologist tested & what not. It broke my chin out in big painful under-the-skin bumps. Womp womp. So I ran out quickly & purchased Physician's Formula powder because it was the only thing that I thought I could really put on my skin. It didn't last long and it was very sheer, so the next day I went to Sephora & picked this up. This foundation gives excellent coverage. It's not too heavy, it doesn't look cakey, it stays ALL DAY & NIGHT! I feel that it makes your skin look perfect without looking unnatural. The brush it comes with works very well, you just have to get used to it. It needs to be buffed in circles and it'll look flawless, trust me! I find that this compact lasts about 2 months because a little goes a really REALLY long way. I only have to dip about 3-4 times during my full face application. You will still need to moisturize, because it will minimally cling to any flaking.
**ALERT! -- I have slept, yes SLEPT in this makeup (I know that's bad, but some weekends us youngin's get a little belligerent) and it had absolutely no negative effects on my skin what so ever. It also looked just as good when I woke up... can't say the same for my eye makeup or my hair, lol.
I will definitely repurchase, I just wish I could find somewhere that carried ALL the shades as I feel Illusion is a little too yellow for me.
EDIT: I bought a second compact of this because I loved it so much. However, I've realized that this is not a good everyday foundation. It's drying on my skin for some reason & shows the flakes as well. Also, I used it while I was visiting friends in NC & I got about 4 cystic acne bumps on my chin. The whole other compact went without any of that. I'm not sure if I maybe got a bad batch? Or if it was just the change in climate (which is very possible with my finicky skin). I haven't used it since we've been back in MD though, but I'll let every one know when I do (: I would still use this for going out and when I know I'm going to have pictures taken. I still love it, and it's still HG for me, but like I said, this isn't an every day product.
EDIT: I've recently used this since being back in Maryland and it looks just as good as before. No nodules or cysts since being back home. It does seem much drier than the other compact, but it still looks flawless. I'll keep it in my rotation for sure. Lasts a while when applied properly (buffed in with a light hand) and stays all day. If you've been skeptical about trying this, or have oily skin, get it. You'll love it!
EDIT: I recently tried putting MAC Studio Fix powder over top of this and it looks awesome! It makes it even more flawless. All you need is a little dusting with a big fluffy brush.
EDIT: So, I've realized that my skin has changed, or the formula has, one or the other. This just isn't working for me anymore. My skin eats it in no time and it winds up leaving my skin "crackly" looking, especially on my forehead. I'm so disappointed as these compacts run almost $40. I won't be repurchasing.
