I had braces for six years as a young man! i had them on for about 6 years and my eyes were really dark for those six years! But, they are still darke and i have not had braces for about 8 years now. I bought some iron pills from wallmart hopeing they would make the circles. If the iron pills from wallmart will make it worse then i'm going to toss them in the trash can!
I have been on a juice fast since the first of this year. That has helped the dark circles a little. I'm going for a year on the juice fast!
