Hi,
the black ring on the nose is called seborrheic melanosis, this happens usually in oily skin and people with dandruff. you need to use a antidandruff shampoo on weakly basis and a ketoconazole based cream at nigh over the black spot for 15 days. it would be better if you could send a image of the spot for better diagnosis and treatment
Next Steps
pleas send a image
