Redness around the skin of the nasal folds may be caused by capillary dilatation, rosacea, hormone-dependent dermatitis and other diseases. 1. Capillary Dilatation Disorder (CDD): It may be related to genetic, environmental, physical and hormonal factors, with clinical manifestations of erythema of the skin in the form of dots, spots and asterisks, etc., and redness around the skin of the nasolabial folds may appear in some patients. 2. Rosacea: it is a chronic inflammation of the skin, related to exuberant sebum secretion, mental stress, etc., which can cause reactive dilation of skin blood vessels, leading to the appearance of redness next to the nose. Temperature, spicy food and other stimuli can aggravate the symptoms of redness. 3. Hormone-dependent dermatitis: it tends to occur on both sides of the nose, and is related to the hormones contained in the cosmetics or topical medications usually applied, which can lead to skin flushing after use, causing redness around the skin of the nasal folds. There may be other reasons for the redness around the skin of the nasal folds, so it is recommended that the patient consult a doctor for examination to clarify the cause of the disease and follow the doctor’s instructions for treatment.
