Definition: What is "Acne rosacea"?


Acne rosacea or simply Rosacea is a very common condition which affects over 45 million people all over the world. Although common, it is a misunderstood condition. This often affects white-skinned individuals who are of northwestern European descent. This has been nicknamed as the 'Celtic curse' by some Irish people. This often begins as mere redness & flushing (erythema) right on the center of the face, also the cheeks, forehead & the nose. It can also affect the chest & the neck. As this disorder progresses, other signs come up such as erythema that is semi-permanent; telangiectasia (or the opening of the surface facial blood vessels); small bumps or domed pustules; reddish gritty eyes, stinging or burning sensations & the most advanced cases manifest rhinophyma or lobulated nose. This disorder is often confused with seborrheic dermatitis or acne vulgaris. It can co-exist with these two conditions & it can affect both sexes (with females thrice more vulnerable). This peaks on the age of 30 to 60. the primary diagnosis of this disease is mainly facial & when the ears or the scalp become involved, it is a suggestion of a different illness.


It has been observed recently that patients who suffer from rosacea have their peptide cathelicidin levels elevated. The stratum coeneum tryptic enzyme levels are also at their peak. In the past, antibiotics have been administered to treat rosacea but these often worked only because they inhibit a few SCTE's. Rosacea can be hereditary & white people can have a higher chance of developing the illness because of their genetic predisposition. Women may be more vulnerable to this disease but when men acquire the disease, their cases tend to be more acute. Triggering factors that cause blushes & flushes are: strenuous exercise, direct exposure to sunlight, acute sunburn, anxiety, stress, cold wind & moving in to a different place with a different temperature. Some medications could become irritants that make rosacea progress. If the skin's redness persists after the use of a product, it is imperative that the usage be stopped. Some acne treatments are even known to 'cause' rosacea because the method of application involves chemical peels or microdermabrasion; or high the product could have a high content of tretinoin, benzoyl peroxide or isotretinoin.


A patient can have one or more of the following sub-types of Rosacea: erythematotelangiectatic rosacea (facial redness that is permanent) with blushing & flushing tendencies); papulopustular rosacea (a portion of permanent redness with papules or reddish bumps & pustules which is often interchanged with acne); phymatous rosacea which is often linked with rhinophyma or nose enlargement; ocular rosacea or dry, red irritated eyelids & eyes.
