There are several reasons for the nose to become larger: first, developmental reasons, and family genetics have a direct relationship. If it is caused by this kind of reason, the appearance can only be changed later by means of surgical plastic surgery. Secondly, diseases of the skin outside the nose, such as rosacea, or more serious hair follicle infection. It is recommended to use anti-inflammatory ointment to apply, such as Bactroban. If the infection is serious, you can also use ointment for external use. Third, diseases in the nasal cavity, such as more serious nasal polyps, or papillomas, which cause changes in the appearance of the nose. Once this condition is diagnosed, it needs to be treated with early surgery, otherwise it will cause other complications in addition to changes in the appearance of the nose.
