Suddenly, have dark circles under eyes

With a fair complexion, everything like that looks worse on me than someone who has a little more color! I can easily get dark circles when tired/under stress but don't recall whether they were more pronounced during chemo. The skin in that area is thin which means there is not as much pigment or epithelial tissue to cover dilated blood vessels, etc. Ask your clinic nurses what they usually see and if people get back to normal quickly once treatment is over so you'll know what to expect.

The Look Good Feel Better classes put on by the American Cancer Society are nice due to the makeup tips & free samples they provide and can prove helpful in situations like this...
