Hello everyone, I have been suffering from pcos for a decade. And has gotten habitual of facial hair and dark neck, however, now I have started noticing visible dark spots on the neck. I have been applying vitamin C at night and also reapplying my sunscreen throughout the day. But it is only making it worse. Is this something serious or will go away with over the counter skincare products. The dark spots are not visible via camera. But the darkening of the neck is getting worse.
