Worst concealer for me

I went to my local Sephora looking for a concealer for under eyes. I have combination skin as well as sensitive skin. The worker recommended this one ...so I read some reviews and did a little research on the product and all seemed great until I used it. It caked up no matter what I did or how little product I used. It looked absolutely horrible and you could notice my fine lines like never before, fine lines appeared that I didn't even know I had. So thick and heavy. I tried my fingers, brush, beauty blender..nothing helped it look any better. I quickly returned it after a few tried.
