Darkcircles, pigmentation. Need help.

Hello, After delivery I have severe dark circles, initially it was due to no sleep in the night, however it's been month no issue in sleeping and am using so many home remedies to get rid off dark circles and pigmentation. Could you please help me with any vitamin supplements or what should I include in my diet to get rid off this issue. Am drinking 2litres of water. Came across this glutone 1000 tablet ,can I take this to reduce pigmentation. Please advise,as I feel  demotivated to see my Terrible dark circles, despite trying so many home remedies for almost month. I have to face ppl in Office during meetings and most of the time, I wear glass to hide my dark circles and cannot do eye to eye contact. Need help. Thanks
