Treatment options for dark circles
Dark circles around the eyes can be caused by deeply set eyes that tend to be cast in shadows, and therefore it is not due to the skin itself.
Another cause could be skin pigmentation which could cause a brown appearance to the area. This could be treated with skin bleachers, chemical peels, microdermabrasion (sometimes alone, and sometimes in combination with other treatments), and laser skin resurfacing.
The other thing that sometimes causes dark circles is the blue color from veins...
