The reasons for dark circles are as follows : 1. Hereditary (inherited from family) 2. Due to an unhealthy lifestyle (late night, junk food , stress, no exercise, being overweight etc) ..Hereditary is difficult to treat but if faulty lifestyle is the reason then modifying lifestyle works like magic. Exercise 60 min everyday, eat healthy and balanced diet, and sleep on time (10 pm). 8 hours sleep is important BUT what is MORE important is that this sleep is at the right TIME. Creams usually don't work well which is why in your case you didn't get a response. So my suggestion is that you visit an allopathic dermatologist near you and start treatment PLUS start modifying lifestyle ASAP. All those tv commercials and models showing miraculous cure of their dark circles is fake.
