Rosacea is a possible reason that a person's face is always red, according to the NetDoctor medical team. It is a chronic skin condition that causes the nose and cheeks to become unusually red and mostly affects women.
NetDoctor explains that rosacea typically starts with temporary flushing and worsens when a person drinks alcohol or a hot beverage, eats spicy foods or stays in hot environments. It often recurs after five to 10 years and disappears on its own. This skin condition causes redness, swelling and acne-like sores, says Healthline. It typically occurs in women from ages 30 to 50.
Healthline states that skin flushing is sometimes linked to an underlying medical problem, such as Cushing's disease, which is caused by high cortisol levels in the body. It also results from an overdose of niacin. Moreover, extreme emotions are likely to trigger facial redness. Feelings of intense stress, sadness, anger or embarrassment tend to cause red blotches on the face and neck. These emotions can be a sign of an acute blood pressure increase.
For facial redness caused by rosacea, the recommended treatment is a lengthy course of the antibiotic tetracycline, according to NetDoctor. Medications, such as beta-blockers, can also decrease flushing. Psychotherapy helps a person manage anxieties that trigger emotional causes of blushing.
