Is the MAC Studio Finish Concealer Good For Under-Eye Circles?

I have horrible under eye circles, not due to lack of sleep, but because when I was born, I was born with smaller nostrils than normal, which makes me very congested all the time and nasal congestion is the most common factor of under eye circles. I have horrible ones, they are purple-ish tones and very puffy. I would like to know if the MAC Studio Finish Concealer is good for my purpose? I've heard that it creases and that it is dry, but I've also heard that it works wonders, so I'm really not sure which is really true. I have normal to oily skin and I am looking for something that will last me all day and not look cakey or anything. Answer?
