Rosacea is a persistent skin disorder that causes redness, tiny pimples, and noticeable blood vessels, usually on the central area of the face.

  • The cause is unknown.

  • Typical symptoms include redness, small visible blood vessels, and sometimes small pimples that appear on the cheeks and nose.

  • The diagnosis is based on the typical appearance of the rash and on the person's age when symptoms first appear.

  • Worsening of rosacea may be prevented by avoiding certain foods, alcohol, hot beverages, and exposure to sunlight, extremes of temperature, wind, and cosmetics.

  • Treatment includes antibiotics applied to the skin or, for some people, taken by mouth.

Rosacea typically affects people aged 30 to 50. The disorder is most common among people of Irish and Northern European descent who have fair complexions, but it does affect and is probably under-recognized in darker-skinned people. Although usually easy for doctors to recognize, rosacea sometimes looks like acne Acne Acne is a common skin condition causing pimples and other abnormalities on the face and upper torso.

The cause of rosacea is not known, but some people may be prone to developing this disorder.

Spicy foods, alcohol, or hot beverages may trigger flare-ups. Other triggers may include sunlight, sunscreen, emotional stress, cold or hot weather, exercise, wind, cosmetics, and hot baths.

Some drugs, such as amiodarone, corticosteroids that are applied to the skin or inhaled through the nose, and high doses of vitamins B6 and B12 may worsen rosacea.

Symptoms of Rosacea

Rosacea affects only the face and scalp. It has four phases:

  • Pre-rosacea phase (phase 1): The skin over the cheeks and nose becomes flushed, but for longer periods of time than normal, and may sting.

  • Vascular phase (phase 2): The skin appears red and swollen, with small blood vessels visible just below the surface (called telangiectasia).

  • Inflammatory phase (phase 3): Often small pimples develop, sometimes with some pus (called pustules).

  • Late phase (phase 4): In some people, the skin around the nose occasionally thickens, making it look red and bulbous (called rhinophyma).

Examples of Rosacea

Rosacea that affects the eyes (called ocular rosacea) often accompanies rosacea that affects the face. Symptoms of ocular rosacea may include inflammation of the eyelids, conjunctiva, iris, sclera, cornea, or a combination that causes itching, a feeling as though something is in the eye (foreign body sensation), redness, and swelling of the eye.

Diagnosis of Rosacea

  • A doctor's examination

Doctors base the diagnosis of rosacea on the typical appearance of the rash. There are no specific tests. The person's age when the symptoms first appear and a lack of blackheads and whiteheads help distinguish rosacea from acne.

Treatment of Rosacea

  • Avoidance of triggers

  • For inflammatory rosacea, antibiotics taken by mouth or applied to the skin or azelaic acid or ivermectin applied to the skin

  • For flushing, brimonidine gel or oxymetazoline cream

  • For telangiectasia, lasers and electrocautery

  • For rhinophyma, dermabrasion, lasers, and/or removal of excess tissue

The first treatment of rosacea is avoiding triggers. Treatment is aimed at controlling symptoms because there is no cure for rosacea.

Antibiotics that are applied to the skin, such as metronidazole, benzoyl peroxide, clindamycin, minocycline, and erythromycin, as well as azelaic acid cream may be effective for inflammatory rosacea. Ivermectin cream is also effective. Corticosteroids applied to the skin tend to make rosacea worse.

Certain antibiotics taken by mouth are given to people who have many pustules or ocular rosacea. Doxycycline, tetracycline, minocycline, azithromycin, or erythromycin is usually used. Isotretinoin may be effective when taken by mouth but, because of possibly severe side effects, is not used unless other treatments are ineffective.

Persistent flushing or redness may be treated with brimonidine gel or oxymetazoline cream.

Treatment of telangiectasia includes laser treatment and electrocautery (an electrical current applied to the skin removes the telangiectasia).

Severe rhinophyma is unlikely to improve completely with drugs. Therefore, a person with this disorder may need dermabrasion (a procedure in which the skin surface is rubbed with an abrasive metal instrument to remove the top layer), laser treatment Using Lasers to Treat Skin Problems Using Lasers to Treat Skin Problems , and/or surgery to remove the excess tissue.
