Stay With Me Longlasting Concealer

The product has hardly any coverage and you can spread it out in no time. I tried applying it with my fingers, brush & beauty blender, nothing works. I had to get another concealer right away because it doesn't work at all. Of course, it's a waste of money to throw away the concealer now, so I'm using it to mix it with my foundation.

I bought this concealer yesterday and tested it out this morning, I picked a colour lighter as my own skin tone, but it is discolored/dark after and not a little bit too, if I use it I have even darker circles under the eyes when I have my own, it doesn't cover and everything comes through it so thick afrader of me.
