What are the benefits?

Vitamin K has been widely marketed as the "cure" for dark circles. Research done has shown that it improves dark circles. However, the study did not use Vitamin K exclusively but a combination of emu oil and caffeine though Vitamin K was sole credited for the results. There is no direct evidence that Vitamin K can improve dark circles.
