Nasal alar contraction belongs to plastic surgery. It is best to be treated with antibiotics in the plastic surgery department of a regular hospital, and charge according to the regulations. Don't worry.

Advertising is usually a privately run beauty salon or a privately contracted department of a hospital, mainly for profit. I don't think it is credible. I have had plastic surgery in the 260 Hospital of the People's Liberation Army in Shijiazhuang, which is a military hospital. It feels very credible and the effect is very satisfactory. You are in Ningbo. I wonder which hospital is good. It is best to be a regular hospital. If it is the People's Liberation Army Hospital, it will be more reassuring.
