Red Rings around the Eyes

I read that red circles under the eyes are caused by

1. anemia
2. lack of sleep
3. aging
4. food/medicine allergies
5. dehydration and caffeine
   
   
   I have one of the four. I am aging. Now at the age of 47, no matter what I do, with makeup or without, I have nasty red circles under both eyes. For a long time, I blamed the pc and all the reading I do. I thought it was eye strain.
   Apparently it's not and that's worse for me because it seems like I have to remain looking this way. I've used some concealers but it doesn't seem like they help.

   These stick concealers are very try and pull on the skin.
