    Rosacea is a common but often misunderstood condition that is estimated to affect over 45 million people worldwide. It affects fair-skinned people of mostly north-western European descent, and has been nicknamed the ‘curse of the Celts’ by some in Ireland. It begins as erythema (flushing and redness) on the central face and across the cheeks, nose, or forehead but can also less commonly affect the neck and chest. As rosacea progresses, other symptoms can develop such as semi-permanent erythema, telangiectasia (dilation of superficial blood vessels on the face), red domed papules (small bumps) and pustules, red gritty eyes, burning and stinging sensations, and in some advanced cases, a red lobulated nose (rhinophyma). The disorder can be confused and co-exist with acne vulgaris and/or seborrheic dermatitis. Rosacea affects both sexes, but is almost three times more common in women, and has a peak age of onset between 30 and 60. The presence of rash on the scalp or ears suggests a different or co-existing diagnosis, as rosacea is primarily a facial diagnosis.

    There are four identified rosacea subtypes and patients may have more than one subtype present.

    Erythematotelangiectatic rosacea: Permanent redness (erythema) with a tendency to flush and blush easily. It is also common to have small blood vessels visible near the surface of the skin (telangiectasias) and possibly burning or itching sensations.
    Papulopustular rosacea: Some permanent redness with red bumps (papules) with some pus filled (pustules) (which typically last 1-4 days); this subtype can be easily confused with acne.
    Phymatous rosacea: This subtype is most commonly associated with rhinophyma, an enlargement of the nose. Symptoms include thickening skin, irregular surface nodularities, and enlargement. Phymatous rosacea can also affect the chin (gnatophyma), forehead (metophyma), cheeks, eyelids (blepharophyma), and ears (otophyma).Small blood vessels visible near the surface of the skin (telangiectasias) may be present.
    Ocular rosacea: Red, dry and irritated eyes and eyelids. Some other symptoms include foreign body sensations, itching and burning.

    Rosacea has a hereditary component and those that are fair-skinned of European or Celtic ancestry have a higher genetic predisposition to developing it. Women are more commonly affected but when men develop rosacea it tends to be more severe. People of all ages can get rosacea but there is a higher instance in the 30-50 age group. The first signs of rosacea are said to be persisting redness due to exercise, changes in temperature, and cleansing.

    Triggers that cause episodes of flushing and blushing play a part in the development of rosacea. Exposure to temperature extremes can cause the face to become flushed as well as strenuous exercise, heat from sunlight, severe sunburn, stress, anxiety, cold wind, moving to a warm or hot environment from a cold one such as heated shops and offices during the winter. There are also some foods and drinks that can trigger flushing, these include alcohol, foods and beverages containing caffeine (especially, hot tea and coffee), foods high in histamines and spicy food.

    Certain medications and topical irritants can quickly progress rosacea. If redness persists after using a treatment then it should be stopped immediately. Some acne and wrinkle treatments that have been reported to cause rosacea include microdermabrasion, chemical peels, high dosages of isotretinoin, benzoyl peroxide and tretinoin. Steroid induced rosacea is the term given to rosacea caused by the use of topical or nasal steroids. These steroids are often prescribed for seborrheic dermatitis. Dosage should be slowly decreased and not immediately stopped to avoid a flare up.

    Treating rosacea varies from patient to patient depending on severity and subtypes. Dermatologists are recommended to take a subtype-directed approach to treating rosacea patients.

    Trigger avoidance can help reduce the onset of rosacea but alone will not normally cause remission for all but mild cases. The National Rosacea Society recommends that a diary be kept to help identify and reduce triggers.

    It is important to have a gentle skin cleansing regimen using non-irritating cleansers. Protection from the sun is important and daily use of a sunscreen of at least SPF 15 containing a physical blocker such as zinc oxide or titanium dioxide is advised.

    Oral tetracycline antibiotics (tetracycline, doxycycline, minocycline) and topical antibiotics such as metronidazole are usually the first line of defense prescribed by doctors to relieve papules, pustules, inflammation and some redness. Oral antibiotics may also help to relieve symptoms of ocular rosacea. If papules and pustules persist, then sometimes isotretinoin can be prescribed. Isotretinoin has many side effects and is normally used to treat severe acne but in low dosages is proven to be effective against papulopustular and phymatous rosacea.

    The treatment of flushing and blushing has been attempted by means of the centrally acting α-2 agonist clonidine, but there is no evidence whatsoever that this is of any benefit. The same is true of the beta-blockers nadolol and propanolol. If flushing occurs with red wine consumption, then complete avoidance helps. There is no evidence at all that antihistamines are of any benefit in rosacea.

    People who develop infections of the eyelids must practice frequent eyelid hygiene. Daily scrubbing the eyelids gently with diluted baby shampoo or an over-the-counter eyelid cleaner and applying warm (but not hot) compresses several times a day is recommended.

    CO2 lasers can be used to remove excess tissue caused by phymatous rosacea. CO2 lasers emit a wavelength that is absorbed directly by the skin. The laser beam can be focused into a thin beam and used as a scalpel or defocused and used to vaporise tissue. Low level light therapies have also been used to treat rosacea. One alternative skin treatment, fashionable in the Victorian and Edwardian eras, was Sulphur. Recently Sulphur has re-gained some credibility as a safe alternative to steroids and coal tar.

    Rosacea is a common inflammatory condition of the skin of the face that causes redness that looks like a flush or blush. It is initially characterised by outbreaks and periods of improvement. Rosacea is sometimes called acne rosacea, which is misleading because rosacea and acne are two totally different conditions, although they can appear together. Rosacea occurs in both men and women and, although it may occur at any age, onset usually begins after the age of 30. People with rosacea often find that certain lifestyle and environmental factors trigger a flare-up or aggravate their individual conditions. Common triggers include certain foods (especially hot or spicy foods) and drink, (especially alcohol and caffeine), exercise, temperature changes, exposure to the sun, rain or wind, and stress. The condition responds to treatment but cannot be cured. Left untreated, the redness becomes more permanent and the tiny blood vessels may become more visible. Pimples often develop and in a few people, especially older men, the nose may become bumpy, red and swollen (Rhinophyma).
