Hylexin Eye Cream by Bremenn Research Labs was designed especially for serious under-eye dark circles.  Getting rid of serious dark circle helps in making you look less tired or old. 

Studies also show that Hylexin works well to strengthen the capillary matrix to prevent the tiny little capillaries to deposit blood around your sensitive eye area which later turns deep purple, which is the major cause for these serious dark circles (via Bremenn Labs official website).  Cost: $95.
