I've been using this for 4 or 5 days but it looked like after the 1st day I could see a bit of difference. I have really dark undereye circles because of allergies and dry eye condition. This is really helping the darkness.
The like the texture. I'm experimenting with the whole highlighting contouring thing. So far I like the palette. I'm only using 3 Colors on the darker end and I like the coverage.
