This product is very useful for unifying the eyelid and hide redness and veins. You can also use a small amount under your eyes because the yellow tone will counter blue dark circles.

But, you have to be careful and use a very small amount because it dries fast and can look quite caky. It also a bit hard to apply because it's thick and again, it dries fast. I would suggest to apply it with your fingers to keep it warm instead of using a brush.

Since it's kind of expensive, I don't think it's really worth it. There's plenty of drugstore products that can do the same thing. Personally I rather use a tiny bit of BB creme.
