Black (dark) or yellow skin around the eyes is a good indicator of liver problems (sluggish for instance). Perhaps you might want to tackle the problem from this angle, and see if you have any luck.
Here's an interesting webpage I found about the liver, and the various things one can do to make sure theirs is healthy, and functioning properly.
It also lists other symptoms of a weak/sluggish/toxic liver, that you may, or may not, also be suffering from, to help you better determine whether (or not) this problem is related to your liver.
Note: if you do not suffer from any other symptom, that does not necessarily mean it
isn't liver related. But if you do, it will just give you a better indication.
It wouldn't hurt to give your liver a little tlc anyway.
