Redness generally refers to dilated capillaries. Redness next to the nose is not necessarily rosacea. There are many causes of redness next to the nose, such as congenital skin weakness, dilated capillaries next to the nose, as well as hormone-dependent dermatitis and rosacea, all of which can cause redness next to the nose. Rosacea, also known as rosacea, is one of the aforementioned causes of redness around the nose. After repeated episodes of superficial dendritic capillary dilatation in the nose and cheeks and persistent localized redness, often accompanied by enlarged follicular pores in the nose and seborrhea, the face becomes flushed and congested with blood and self-consciousness when eating spicy foods or hot drinks, elevated ambient temperatures, or when emotionally impulsive. To clarify the cause of the disease, please go to the dermatology department of a regular hospital.
