I have been observing pigmentation around my nose and below lower lip region from around 5 years and it is gradually increasing now I have consulted dermatologist and they prescribed kojivit ultra cream and lulibrut cream and i?m using it from one month and I see no change. And I was diagnosed with pcod 3 years back now my periods were regular! my question is how to get rid from that pigmentation .is that related to my pcod problem? What should I do to overcome this pigmentation?
