What causes Rosacea?

Rosacea CheekRosacea is a non contagious disorder of the skin which causes inflammation on the face. The first signs are generally frequent flushing or blushing to the face. In later stages the skin exhibits a permanent flush and sufferers can sometime develop pimples  in the effected areas. It is caused by the enlargement of the blood vessels (capillaries) closest to the surface of the skin, this dilation is what gives Rosacea that red flushed appearance.

The cause of Rosacea is unknown and there is no cure for the disorder. If left untreated the symptoms generally worsen with age and in some cases may lead to the development of deformities which cause redness, enlargement and a fibrous thickening of the nose (rhinophyma).

Common symptoms of Rosacea

While the cause of rosacea is unknown and there is no cure, we can still offer effective treatment to control the signs and symptoms of this potentially life-disruptive disorder. Common signs to watch out for include:

  • Enlarged capillaries (telangiectasis)
  • Frequent and lasting flush across the nose and cheeks
  • Yellow-headed pimples on the forehead, cheeks and chin
  • Non-tender lumps under the skin
  • Swollen cheeks and nose (hyperplasia)
  • Frequent blushing
  • Burning or stinging sensations
  • Facial rashes


Environmental triggers for rosacea

There are many environmental factors that can trigger rosacea or cause it to worsen, these include:

  • Alcohol
  • Coffee and tea and hot drinks
  • Spicy foods
  • Overexposure to sunlight
  • Anxiety and emotional stress
  • Overheating, especially in bed at night


Correction and management of Rosacea

Options available for the treatment and management of rosacea are dependant on the severity, and may include:

  • The avoidance of known triggers such as sun exposure, alcohol and spicy foods
  • Antibiotics such as doxycycline can help reduce the severity of the rash and generally start to work after three to four weeks after commencing the course and take six weeks to completely clear rosacea. Two thirds of people have a prolonged remission after a single course of antibiotic. One third relapse within a few months and may require maintenance therapy
  • Creams and gels containing antibiotics to be applied to the skin
  • Laser surgery to treat the enlarged capillaries and to reduce inflammation
  • Laser skin resurfacing to treat the nose, if affected by rhinophyma.
