I have widespread brown patchcovering my whole chest area. It was smaller in size during my childhood years but literally seemed to grow or expand. It also has a few pimples here and there. It bothers me a lot as I feel underconfident to wear certain dresses.  Is there any home remedy or lotion or treatment to lighten it or much better to totally vanish it? Some doctors told that it can't be removed which inturn made me worried? Please help!
