Dark circles are a very notorious condition and do not respond easily to treatment. In patients with dark circles certain underlying conditions need to be ruled out like nutritional deficiencies or certain inflammatory conditions. In case the secondary causes are present, they need to be addressed 1st to get a better response to treatment. Also, dark circles respond slowly and you have to be patient with the treatment and continue applying the cream for a few months to see some change. You can try using Brunda Under eye cream or RoC Sublime cream or Under Eyes 20 gel or Ega cream or WonderEye cream for a few months. But I would advise getting a consult done online or meeting a certified dermatologist to rule out any aggravating coexisting conditions. Hope this is helpful.
