Rosacea (pronounced "roh-ZAY-sha") is a chronic and potentially life-disruptive disorder primarily of the facial skin, often characterized by flare-ups and remissions. Many have observed that it typically begins any time after age 30 as a redness on the cheeks, nose, chin or forehead that may come and go. In some cases, rosacea may also occur on the neck, chest, scalp or ears.
Over time, the redness tends to become ruddier and more persistent, and visible blood vessels may appear. Left untreated, bumps and pimples often develop, and in severe cases the nose may grow swollen and bumpy from excess tissue. This is the condition, called rhinophyma (pronounced "rhi-no-FY-muh"), that gave the late comedian W.C. Fields his trademark bulbous nose. In many rosacea patients, the eyes are also affected, feeling irritated and appearing watery or bloodshot.
Although rosacea can affect all segments of the population, individuals with fair skin who tend to flush or blush easily are believed to be at greatest risk. The disease is more frequently diagnosed in women, but more severe symptoms tend to be seen in men -- perhaps because they often delay seeking medical help until the disorder reaches advanced stages.
While there is no cure for rosacea and the cause is unknown, medical therapy is available to control or reverse its signs and symptoms. Individuals who suspect they may have rosacea are urged to see a dermatologist or other knowledgeable physician for diagnosis and appropriate treatment.
What Should I Look For?
Rosacea can vary substantially from one individual to another, and in most cases some rather than all of the potential signs and symptoms appear. According to a consensus committee and review panel of 17 medical experts worldwide (see Classification of Rosacea), rosacea always includes at least one of the following primary signs, and various secondary signs and symptoms may also develop.
Primary Signs of Rosacea
Many people with rosacea have a history of frequent blushing or flushing. This facial redness may come and go, and is often the earliest sign of the disorder.
- Persistent Redness
Persistent facial redness is the most common individual sign of rosacea, and may resemble a blush or sunburn that does not go away.
- Bumps and Pimples
Small red solid bumps or pus-filled pimples often develop. While these may resemble acne, blackheads are absent and burning or stinging may occur.
- Visible Blood Vessels
In many people with rosacea, small blood vessels become visible on the skin.
Other Potential Signs and Symptoms
- Eye Irritation
In many people with rosacea, the eyes may be irritated and appear watery or bloodshot, a condition known as ocular rosacea. The eyelids also may become red and swollen, and styes are common. Severe cases can result in corneal damage and vision loss without medical help.
- Burning or Stinging
Burning or stinging sensations may often occur on the face. Itching or a feeling of tightness may also develop.
- Dry Appearance
The central facial skin may be rough, and thus appear to be very dry.
Raised red patches, known as plaques, may develop without changes in the surrounding skin.
- Skin Thickening
The skin may thicken and enlarge from excess tissue, most commonly on the nose. This condition, known as rhinophyma, affects more men than women.
Facial swelling, known as edema, may accompany other signs of rosacea or occur independently.
- Signs Beyond the Face
Rosacea signs and symptoms may also develop beyond the face, most commonly on the neck, chest, scalp or ears.
Subtypes of Rosacea
The consensus committee and review panel of 17 medical experts worldwide identified four subtypes of rosacea, defined as common patterns or groupings of signs and symptoms. These include:
- Subtype 1 (erythematotelangiectatic rosacea), characterized by flushing and persistent redness, and may also include visible blood vessels.
- Subtype 2 (papulopustular rosacea), characterized by persistent redness with transient bumps and pimples.
- Subtype 3 (phymatous rosacea), characterized by skin thickening, often resulting in an enlargement of the nose from excess tissue.
- Subtype 4 (ocular rosacea), characterized by ocular manifestations such as dry eye, tearing and burning, swollen eyelids, recurrent styes and potential vision loss from corneal damage.
Many patients experience characteristics of more than one subtype at the same time, and those often may develop in succession. While rosacea may or may not evolve from one subtype to another, each individual sign or symptom may progress from mild to moderate to severe. Early diagnosis and treatment are therefore recommended.
How is Rosacea Treated?
Because the signs and symptoms of rosacea vary from one patient to another, treatment must be tailored by a physician for each individual case.
Various oral and topical medications may be prescribed to treat the bumps, pimples and redness often associated with the disorder. Dermatologists often prescribe initial treatment with oral and topical therapy to bring the condition under immediate control, followed by long-term use of the topical therapy alone to maintain remission. A version of an oral therapy with less risk of microbial resistance has also been developed specifically for rosacea and has been shown to be safe for long-term use.
When appropriate, treatments with lasers, intense pulsed light sources or other medical and surgical devices may be used to remove visible blood vessels, reduce extensive redness or correct disfigurement of the nose. Ocular rosacea may be treated with oral antibiotics and other therapy.
Patients should check with their physicians to ensure their skin-care routine is compatible with their rosacea. A gentle skin-care routine can also help control rosacea. Patients are advised to clean their face with a mild and non-abrasive cleanser, then rinse with lukewarm water and blot the face dry with a thick cotton towel. Never pull, tug or use a rough washcloth.
Patients may apply non-irritating skin-care products as needed, and are advised to protect the skin from sun exposure using a sunscreen with an SPF of 15 or higher.
Cosmetics may be used to conceal the effects of rosacea. Green makeup or green-tinted foundations can be used to counter redness. This can be followed by a skin-tone foundation with natural yellow tones, avoiding those with pink or orange hues.
In addition to medical treatment, rosacea sufferers can improve their chances of maintaining remission by identifying and avoiding lifestyle and environmental factors that trigger rosacea flare-ups or aggravate their individual conditions.
