Rosacea symptoms, which tend to worsen periodically, can be triggered by the following:
Although the specific causes of rosacea are unknown, a combination of hereditary and environmental factors appears to be involved.
Symptoms of rosacea are usually visible on the nose, cheeks, mouth and forehead; they occasionally spread to the neck, chest, scalp or ears. Symptoms typically come and go, flaring up for weeks or months, and then fading for a period of time. They tend to worsen as the condition progresses, and are sometimes used to distinguish its four stages.
Pre-rosacea symptoms include frequent flushing or blushing, which progresses to a persistent redness on the face. Vascular rosacea symptoms involve the swelling of small blood vessels (commonly referred to as spider veins and, medically, as telangiectasia) around the nose and cheeks. Oily skin and dandruff are also common during this phase. Inflammatory rosacea is the stage during which small bumps or pustules begin to develop; they then spread across the nose, cheeks, forehead and chin. Late rosacea is the most advanced phase, during which all earlier symptoms intensify.
If left untreated, symptoms continue to worsen, and may cause permanent skin damage. Some patients develop a form of the disorder that affects the eyes (ocular rosacea), and which may, in severe cases, affect vision. The symptoms of rosacea may include the following:
In late rosacea, patients may develop a complication called rhinophyma in which facial tissue builds up and hardens, causing the nose to enlarge and become bulbous. This complication is more common in men than women.
Diagnosis of rosacea is typically made through a simple physical examination of the skin on the face. Sometimes tests are administered to rule out other possible causes, such as eczema or lupus. Although there is no cure for rosacea, several treatments are available to relieve symptoms. Through medical consultation, patients should be able to pinpoint at least some of their symptoms’ triggers, and learn to avoid them. It may be necessary for them to avoid the sun, spicy foods, alcoholic beverages, or certain medications. Participation in a stress-management program may also be recommended.
Using makeup to disguise rosacea helps many sufferers feel less self-conscious. Medical treatments, the use of which depends on the severity of the condition, may include the following:
If the patient is suffering from symptoms of ocular rosacea, oral antibiotics and steroid eye drops may be prescribed.
