Q: I am 46 years old. I was suffering from Seborrhoeic dermatitis for the past 20 years. Since then my face has begun to darken. My face is still black whereas other parts of my body are white. I do not go outside if it is too hot. Why has my skin darkened? I had taken medicine for Seborrhoeic dermatitis, but it has helped only a little. Please suggest how I can improve my skin colour.

A:If at present there are no signs of active dermatitis, itching, redness or rashes, you can use skin lightening creams / lotions such as Kojic acid or Hydroquinone.
