The color match is actually surprisingly good, given that the concealer only comes in one shade (10, Natural Beige), but that's about the only positive thing I can say about it. First of all, it doesn't have nearly as good coverage as I initially thought, I use about 3-4 layers of the stuff on a blemish, and even then the coverage is mediocre at best (By the way, the reason I thought it would cover well is because I tested it on a bug bite scar on my hand, it it covered that up really well. Very misleading!). It also has no staying power; after about 2 hours, I have to touch up, and I am the kind of person who likes to put on makeup in the morning and not have to worry about it the rest of the day. And, as you can see in the photos, I've already hit serious pan on it, even though I've only been using it for 3 weeks.
So, all in all, I would not recommend this concealer, which is a pity because I had such high hopes for it. But I guess this is a case of getting what you paid for, since it only cost about 3 euros. Some inexpensive drugstore products are awesome, but this isn't one of them!
