Rosacea is a chronic inflammatory condition in which flushing of the skin in the areas of the forehead, nose, cheekbones, and chin becomes recurrent or permanent and marked (erythema). It may cause permanent redness, vascularity (increased prominence of the blood vessels), swelling or hyperplasia (increase in size of the tissue), or skin bumps and eruptions similar to acne: small, red and solid (papules) or pus-filled (pustules).

Similar to acne, rosacea has a significant economic cost and psychosocial impact. Because the features of rosacea are so visible, people with rosacea are often distressed and embarrassed about their appearance and may exhibit low self-esteem. Negative effects on psychological well-being may extend to social and business relationships.

The cause of rosacea is unknown and there is no cure. This vascular disorder involves enlargement of the blood vessels just under the skin, which may become visible spidery veins (telangiectasis) and oil glands. Long-term rosacea may produce a permanently enlarged and nodular nose (rhinophyma, nasal bumps), the result of recurrent facial swelling that leads to overgrowth of tissue (fibroplasia).


Rosacea is a common, chronic dermatosis estimated to affect at least 1 in 20 people in the USA. The majority are fair-skinned, Caucasian women, aged 30-50 years old. One community study found 10% of those examined had rosacea (14% were women, 5% were men). Whilst women are more commonly affected, men are usually more severely affected. Rosacea may be associated with a migraine headache, other skin disorders (acne vulgaris, seborrhea), or eye disorders (blepharitis, iritis, keratitis conjunctivitis and corneal vascularization). Ocular involvement occurs in more than 50% of patients, the decade of prevalence being 51-60 years. It is one of the most common skin conditions with at least 13 million Americans known to be affected.

Rosacea has been noted in people as diverse as African Americans and Koreans, but it occurs most often in fair skinned people, particularly those who blush easily. Often called the "Curse of the Celts," rosacea is especially prevalent among individuals of Irish descent and also Scandinavian. Other ethnic categories with elevated rates of rosacea in the survey included Scottish, Welsh, Polish, Lithuanian and Balkan nationalities. There is also good indication that it is familial, for example in one survey 11 percent of adults with rosacea had children already diagnosed with the condition (prerosacea, characterized by frequent blushes or flushes that last a little longer than normal).
