You can heal a crusty nose by applying some coconut oil, lip balm, nose balm, moisturizing lotion and even a warm damp washcloth to the nose.
Also drink more water and increase humidity in your home as dry air and dehydration can lead to dry crusty noses and dry skin.
Nasal crusting is a condition characterized by the formation of dry, hard, or thickened mucus and debris within the nasal passages.
The crusty nose can result from various causes, including dry air, allergies, infections, or underlying medical conditions affecting the nasal mucosa.
Atrophic rhinitis is nasal dryness that occurs when tissue inside of your nose thins or atrophies.
Eventually, the tissue hardens.
As a result, the nasal cavities where air flows through your nostrils widen.
The nasal passages become too dry, causing a foul-smelling nasal crust to form.
The ointment that is safe for inside the nose is Nasal Neosporin.
Nasal Neosporin may help reduce the likelihood of bacteria getting introduced into your body via the nose.
It can also help to heal small abrasions or cuts in the nose.
You can usually apply the nasal neosporin around and slightly inside the nostrils to experience its benefits.
However just note that while Vaseline can be used safely on the outside of the nose it should never be used inside the nose.
You should never, ever use petroleum jelly (petrolatum) or anything oily inside your nose.
Putting Vaseline or any other petroleum jelly inside the nose could be life-threatening, as the oil can get into your lungs, and you can't remove it.
