What to do for post inflammatory pigmentation?

Q: Few months before an insect bite on my penis and I applied dettol twice. But after that, a part of the skin became black and remains same colour for about 10 days. And after that the black part of my skin got white and now its like a burn mark on my penis which looks very bad. It covers an area around half an inch. Can any ointment remove this mark from my penis?

A:If it is just post inflammatory pigmentation, it will disappear within 3 to 6 months, but if it is a scar nothing can remove it other than plastic surgery. You can try Elovera cream and Contactubex gel topically twice daily.
