Dark circles can be really troublesome. Nothing makes you look older and tired than dark circles under your eyes.  They may be genetic or due to nutritional, lifestyle, sunlight, dehydration, allergies and stress factors. Eat lot of fruits, keep hydrated, sleep for 6-8 hours daily at schedule and exercise. After long term problem, the skin is less able to rebound from stress, fatigue, and exposure to environmental elements, even with the aid of nutrition, sleep, and moisturizing lotions. Sunscreen, skin lightening creams, Peels and electroporation , RF or ultrasound can help but you need to take 8-10 sessions weekly or fortnightly

The angle of the picture is not that good a complete picture is required still it does appear to be tear trough quite common in Asians which is giving you that darkening effect once that corrected you achieve a good result along with a lightening cream for your under eye
