Rosacea is a common skin disorder causing facial flushing, papules and pimples and visible blood vessels. Rosacea mostly affects fair-skinned adults between the ages of 30 – 60 and is more common in females, although males may show signs that are more apparent. Surveys show that women are more likely to get redness on the cheek and forehead, while men are more likely to have redness and swelling of the nose. The cause of rosacea is unknown, but common triggers activate the disorder. The top 10 triggers include sun exposure, emotional stress, hot weather, wind, heavy exercise, alcohol consumption, hot baths, cold weather, spicy foods and humidity. Although rosacea cannot be cured, treatments can relieve signs and symptoms. Treatment options include oral antibiotics (e.g. tetracycline) and topical antibiotics (e.g. metronidazole). Other recommendations a healthcare providers may suggest are the use of certain sunscreens, soaps and moisturizers.
