How do I apply this properly?

Good covering concealer. Now I'm not really an expert with these things and I notice that the concealer is getting in line. Now I don't know if it's up to the product or how I apply it. I put two dots under my eye. Towards my left corner of the eye and to the right. Then I gently blot it out with my finger. When it comes down, I notice that it does not stay in place.
