The nasal base is the basal area of the body between the external nose and above the upper lip. The nasal base is composed of skin, blood vessels, nerves, and a small amount of adipose tissue. Clinically, dermatitis, folliculitis and other skin diseases can occur in the nasal base area, which can also be triggered by trauma, heredity and other factors, and the excessive depression of the nasal base affects the facial aesthetics. Compared to other parts of the body, the chances of diseases occurring at the base of the nose are small. Skin diseases such as dermatitis and folliculitis can be treated with antihistamines such as loratadine and antibiotics such as amoxicillin capsules as prescribed by the doctor. For those who have excessive depression of the nasal base, they can be treated with nasal base filler surgery.
