What Is The Treatment For Skin Pigmentation Problems In The Legs?

when i was little i had an iron fall on my foot. I followed directions about not doing anything to it and letting it heal. Only to find out YEARS later, i had burnt off the tissue! The burnt skin is all wrinkly and lighter than my foot. Im so self conscious about my foot now, that i don't even wear flip- flops or sandals or even barefoot like i used to. Please Doc, i need your help!
