Hello! my name is sidra mustafa. I am 22 years old and also unmarried. Recent days, i'm noticing some patches on my nose. I don't go outside or in sun. It looks like, melasma is being developed. But why? They are because of hormonal changes? And also my periods were irregular in this month. Period duration was of 1 day only. Kindly tell me what should I do? What is the main reason of these patches. They are light but can be darker. I'm using hydroquinone plus for this. And it's been 4 days of using it. Hoping for best reply.
