I like it, but I'm not wowed by it, so I wouldn't buy again when (if) I ever finish the one I have.
I have it in shade Neutral, and it's a little too yellow for my NW15 skin even in summer time, with a slight tan. It's okay though, but I cannot see myself getting away with it in the winter time.
What I do like is that it keeps me relatively matte for most of the day, I only get oily in the evening, after 6 pm, after having it on for 11 hours and blotting once or twice mid-day. So it's a good product for hot summers, which is why I gave it the 4 lippies.
I tried using it as a base under my foundation, but it didn't work like that, it all felt gross and cakey.
The way I use it is by soaking a cotton ball into the mixture and applying all over the face, letting it dry for a minute or so, then going over it with my fingers to buff it in. Because it still looks powdery, I then spray some UD All Nighter on top, let it sit for a few seconds, then gently pat it in with my fingers - I find that this removes the powdery look and leaves my face matte, poreless and flawless. I also use a setting powder (Coty Airspun at the moment) on top.
As for coverage, I did pour out about half of the clear liquid (toner), this way the product is more concentrated and I can achieve a medium coverage. I haven't had any active pimples since I've started using it, so I don't know how it would cover them, but I have a feeling it might work. If not, a dab of concealer will do.
I have a feeling it also prevents breakouts, because the toner has alcohol in it and other stuff that apparently is good for the skin.
It has a faint scent but it doesn't linger at all, and it feels a bit drying, especially in the beginning, but the feeling subsides soon after.
As a negative, I find it does pool up in some pores, especially on my nose, but it's not obnoxiously obvious like with other foundations. Does it look like I'm wearing nothing? No. But it does look pretty natural, so it's all good.
I don't think it would be a good product for winter, when skin gets much drier, but I totally recommend it for summer, especially for those who don't need full coverage.
It is expensive, but I don't see myself running out of it anytime soon, so it's worth the price.
