I've had a skin issue where the area around my neck has been darker for almost 5 years, and now I'm noticing that the skin around my nose is starting to darken too. What could be causing this, and what can I do to treat it?
That could be a condition called Acanthosis where hyperpigmentation is the symptom,if your over wt wt loss would help for this condition,visit your dermatologist for evaluation and appropriate management.
