In the year 03 I was on vacation and I swam 30 minutes a night for the 9 days. When I got back home after the 9 days, I noticed I didn't have them any more. Then within (no swimming)a month or so I have them back.
Now with summer coming I hope swimming will get these dark circles to go away.
I am not saying swimming removes them, I just noticed they dissapeared then and all I was doing is swimming and of course the sunshine.
Prayers
