Rosacea

Rosacea is a chronic but treatable skin condition that primarily affects the central face. In as many as 50 percent of patients the eyes are also affected. Although rosacea may develop in many ways and at any age, patient surveys indicate that it typically begins any time after age 40 to 50 as flushing or redness on the cheeks, nose, chin or forehead that may come and go. The true cause of the disease is not yet known. It is a combination of genetic predisposition and more external factors ( food, stress, weather,…). Rosacea has nothing to do with acne,although it may be similar to it. Although rosacea can affect all segments of the population and all skin types, individuals with fair skin, blood type Rh A+ and people who suffer from migraines are believed to be at greatest risk. The disorder is more frequently diagnosed in women, but tends to be more severe in men. There is also evidence that rosacea may tend to run in families, people with genetic predisposition 30-40 % more often. The development of the disease takes place in stages.

What Causes Rosacea

Stages of Rosacea

There are four progressive stages of rosacea:

  1. First stage (predisposition)- Flushing and intermittent facial redness
  2.  Second stage – persistent redness on the cheeks, nose, chin or forhead. Persistent skin discoloration; this may look like a blush or sunburn that does not go away. It happens when hundreds of tiny blood vessels near the surface of the skin expand.
  3. Third stage – small, pus-colored or red bumps, along with tiny blood vessels that appear as red, thin lines ( telangiectasias). People may have irritated, watery, or bloodshot eyes. The eyelids can become red and swollen , and styes are common. Rosacea affects the eyes in around 50 % of people with the condition. Rarely, vision can become blurred.
  4. Fourth stage – bumps and skin thickening of the nose. The skin may get thicker from excess skin tissue. This usually affects the nose and can cause rhinophyma, which affects males more than females.
