I got this infection almost 2 years back. On consulting, I had given with vitamin c, iron tablets and calamine lotion and glowderma/ lumaglow for application. My infection stopped by using sofradex and some other medicine prescribed by a dermatologist but the marks of the infection are not going. The black marks on my arms are getting lighter but the marks on my neck are not changing. Please, suggest me something to get rid of my marks. I'm fed up of applying medicines. Is there any other treatment to remove them fast?
