22+ Black Line On Nose Treatment. Hello, horizontal line on the nose can be due to hyperpigmentation of the skin due to excess deposition of melanin or due to atopic allergies which causes the individuals to push up the nose. If you have black skin you could bleach your nose permanently white whilst trying to remove the dark line.
Prolonged or repetitive nosebleeds, or those caused by an underlying medical condition, require medical attention and treatment.
This line across my nose has been there for a long time, but it just recently occurred to me how it may have possibly have gotten. They often cluster on and around the nose where dead skin and oil can clog pores. By repeatedly pushing your nose up because of itchiness or to wipe it, you cause sebum to build up on the bridge of the nose. Admittedly, it has become a lot worse within the past twelve or so months.
