I was used xerina cream (which contains glyceric acid) around my underarms and this cream burns that area and turns into a dark patch. After that I used skin lite cream (which contains hydroquinone, tretinoin and mometasone furoate) to decrease the pigmentation. It gives wonderful results but when I stopped the application of this cream on that area it turns into more darkness. I was consulted to a dermatologist and he gave me a sodium fusidate cream. Is this cream helpful to achieve my original skin back.
