Hello and Welcome to Healthcare Magic. Thanks for your query. Common causes for having dark pigmentation under the eye are: -Iron deficiency anemia -Stress, anxiety or depression -Lack of sleep, poor sleep hygiene -Poor water intake -Smoking and alcohol -Chronic illness -Unknown causes (idiopathic). So, it is important to identify specific and treatable cause for best result. In most of the cases reasons for having dark circles below eyes are multiple and that s why multimodal approach becomes necessary for the treatment. General treatment consists of: -Iron and B complex vitamins -Apply almond oil around eyes in night -Put slices of cucumber above your eyes daily for 15 minutes -For stress (if present): daily morning walk, meditation and yoga -Proper sleep for 7 to 8 hrs per day, follow sleep hygiene -Plenty of water, fresh fruits, vegetables and salads intake -Using sunscreens: if your skin is sensitive for sunlight If above steps failed (which is less likely), then you should visit dermatologist for treatment options like: Medicines, Chemical peeling and Laser treatment. Best wishes, Dr. Sheeba Stephen
