Rosacea is an inflammatory condition only and unlike acne (acne vulgaris) Rosacea does not cause scarring. Rosacea is a chronic disorder, rather than a short-term condition, and is often characterised by relapses and remissions.
Rosacea occurs predominantly in fair skinned adults, 30 to 50 years of age and persists becoming chronic with age. It occurs more frequently in females, but when it occurs in males it is usually more severe. One in ten patients with Rosacea has a family history of the condition.
Rosacea is an “acnieform eruption”. This means it has many features that make it acne-like in appearance, but it is NOT acne. Thus the old term “acne rosacea” should no longer be used. There are pustules, but no comdones and the condition affects only the face.
There are various forms of Rosacea depending on which skin appearance predominates (including rosacea affecting the nose and eyes), but the most common types mainly cause flushing and telangiectasia or papules and pustules or a combination of both.
