Home Remedy for minor raised scars and loss of skin color scars and very dark undereye circles?

I have all of these minor issues on my face and body except for the major issue of the really bad dark under-eye circles that seem to be hereditary.It seems that nothing i do seems to lighten them up and some days they even seem darker and uglier.Are there any home remedies for all these issues?
How about for lines/wrinkles under the eyes?
