I am of South-Asian decent, Tamil to be specific, 22 years old. I used to suffer from Exzema when I was little, however it has been clear for the last couple years or so. My face used to be so clear, no signs of breaking out or discolouration. However this year I have found a white patch on my face. I have been breaking out a lot, and my face is darker in some areas. What is the treatment for this?
