Rosacea is a chronic skin condition affecting the face, causing redness and inflammation. It most commonly affects middle-aged adults and has a greater prevalence among those with fair-skinned, Caucasian heritage. It is a common disorder of the facial skin, which can affect people of all ages and genders, although it is more frequent in women.

The cause of rosacea is still unknown but some suspect it could be due to underlying vascular abnormalities or an increase in blood vessels close to the surface of the skin. People who suffer from rosacea may also have increased sensitivity to certain substances that can lead to flare-ups. Common triggers include emotional stress, extreme temperatures, hot drinks and spicy foods.

There are several types of rosacea including: papulopustular (red bumps with pus-filled centers), phymatous (thickening or enlargement of the nose), ocular (affecting the eyes) and erythematotelangiectatic (visible red veins or blushing). Each type has its own unique symptoms but all typically cause persistent redness and flushing on the cheeks, forehead, chin or nose.

Treatment for rosacea aims to reduce inflammation while minimising any further damage to the skin. This includes chemical peels with a treatment called Thermavein.
