Hi. I'm 26 and I have a light beige skin tone. I have very brownish skin around my eyes. It goes up to my brow line and below my eyes as well. This is not typical dark circles. It is brown rather than grey or bluish. No amount of extra sleep, water, iron, or anything else seems to help. It has gotten worse over the past 8 years or so. I have heard that it could be caused by some sort of health problem. Any insight would be helpful.
