Hi.. Welcome to HEALTHCARE MAGIC.. I have gone through your query and can understand your concerns.. As per your complain dark circles can occur due to causes like excessive exertion like excess use of computers and mobile phones, stress, malnutrition etc.. I would suggest you to first of all limit use of computers, laptops, cellphones etc.. In case if you are undergoing stress try to reduce stress by doing meditation and breathing exercises.. Take multivitamin supplements daily.. You can apply creams containing Kojic acid, glycolic acid and arbutin. Apply Vitamin E and C containing gels.. You can apply creams containing grape seed extract and tea tree oil as these are very beneficial.. You can put grated potato over the eyes as it will relieve the eyes, sooth the skin as well as reduce dark circles.. You can also pot cucumber slices over the closed eyes.. Avoid excess sun exposure.. Drink plenty of water and take a nutritious diet.. Hope this information helps.. Thanks and regards. Dr.Honey Nandwani Arora.
