Rosacea is a common skin disorder which can occur at any age, but is most likely to start in Caucasians in their 30s and 40s years of age.
The cause of rosacea is not well understood but it is believed that genetics and sun damage play a significant role in Australians who suffer from it.
Rosacea is often asymptomatic although can be associated with increased sensitivity of facial skin or even a persistent itch. There are some things which may worsen the symptoms and signs of rosacea including alcohol, hot foods/drinks, or spicy foods.
It is characterised by easy flushing, red patches, pimples and papules, and broken capillaries particularly affecting the centrifacial zone. The key element that separates rosacea from acne is the lack of comedomes (blackheads) which are a hallmark of acne. In its worst form rosacea can cause disfiguring lumpy growth of the affected area, especially on the nose.
Rosacea may affect the eyes causing gritty sensation and redness of the conjunctivae (whites of the eyes) and eye lid margins.
Whilst the symptoms and signs may wax and wane over time, there are effective treatments to manage most cases of rosacea including topical creams, oral tablets and even laser.
