I m 27 yrs old female suffering from dark circles no eyebags or puffiness only wrinkles around my eyes and dark circles are there. I have to study late nights as I m a medical student and also have no good diet. Inspite of all that my eyes are weak so I m using contact lens from last 2 yrs. Late night studies cause pain in my eyes also. Is excessive crying also the cause of dark circles? pls suggest me some good tips medicines or creams to cure my dark circles soon?
