I was recommended to use this for dark circles and as I was looking for good products to try and do my wedding make up myself, I found this. It sits well on dry dehydrated under eye and makes it bright so it does also cover well dark circles. I will try to use it again to get used to it but the applicator also is very easy to use. The quantity may be small for the price. 

One of the best concealers I have tried

Best concealer in my life. It brights skin and not cakey

the best one for dark circles under the eyes

This is a great product. I have used this for years with no plans to change. The only slight improvement that could be made is the sponge applicator, it gets weak and breaks once it gets moist but I generally just turn to my brushes once this happen because the product is still worth it
