Hi.. Welcome to HEALTHCARE MAGIC.. I have gone through your query and can understand your concerns.. As per your complain dark circle under the eyes can occur due to causes like excessive stress, overuse of laptops,mobiles, reading, malnourishment etc.. I would suggest you to first of all limiting the use of laptop, mobile etc and sleep for atleast 6 to 8 hours a day.. You can start applying creams containing Kojic acid, glycolic acid and arbutin.. Grapeseed extract containing creams are also helpful.. You can do cool compresses to soothe the eyes.. You can keep pieces of cucumber over the eyes to relieve stress.. Grated potato can also be pot around the eyes and over it.. You can take multivitamin supplements.. You can also do meditation and yoga to relieve stress and it will further hlp in improvement.. Hope this information helps.. Thanks and regards. Dr.Honey Nandwani Arora.
