I own this concealer in the shades Beige and Medium. These Concealers can be used anywhere on the face, even on the eyelids. They come in a small pot, but because the concealer is highly concentrated, a little truly does go a long way. So, one small jar really does last a super long time. These Concealers do provide me with medium-to-full coverage. Now, I set them well with powder, so I don't get any major creasing with them at all. A really good oil control powder will allow for these concealers to stay in place all day. Because not all powders are alike, some powders used to set these concealers with, aren't going to be the most compatible, and yes, you may get creasing, caking, and smearing. These concealers are not 100% crease free. So, please don't go by such claims. Neither do I feel that the concealer is lightweight. Because, to me, it goes on just like MAC's StudioFinish concealer, which goes on creamy and stays that way, until you set it real good with a mattifying type of powder.
The only slight con to these concealers is that the way that the color looks in the pot, is not 100% true to how it looks on the face. Which is why, in stores or even online, you have to play this type of guessing game, when it comes to picking out shades, whether it's to use for highlighting, contouring, bronzing, or even just matching your natural skin tone.
I don't apply these concealers with my finger, because this concealer doesn't dry down matte all by itself, it has a very creamy texture, and therefore applying it with my fingers, would greatly affect its performance. The heat from your fingers will start to break down the product a lot more than without, which is why, I highly recommend using an actual concealer brush with this product.
These concealers only retail for $5, and for how long one jar lasts and the coverage that it gives, I feel that it is definitely worth getting for sure. When it comes to concealers, whether high end or inexpensive ones, they all need to be set real well with a powder that has really great mat tidying properties to it, or else, whether you have any fine lines or wrinkles, the concealer will start to break down in some form or fashion. That's just the nature of most concealers, unless a concealer is able to dry down to a totally matte finish and stay that way for several hours on end after application, then you can just apply it and forget about it. But in most cases, you need to set your concealer very well with powder, and the powder that you use should be a very good oil absorbing/mattifying one at that.
