Q: I am 21 years old. When I was a child, I was bitten by mosquitoes, which left black spot marks. Even now those marks persist. How can I get rid of these marks?

A:This is a very easily treatable condition. Please use a cream that contains hydroquinone (2-4%) externally on the dark spots. They usually disappear within six months of regular daily usage. One thing that is often recommended as a home remedy is application of turmeric paste, which you must definitely avoid.
