Rosacea
Rosacea is a chronic skin condition characterized by facial redness, small and superficial dilated blood vessels on facial skin, papules, pustules, and swelling. Rosacea affects all ages and has four subtypes, three affecting the skin and the fourth affecting the eyes (ocular type).
It primarily affects people of northwestern European descent and has been nicknamed the "curse of the Celts" by some in Britain and Ireland, although such a connection has been questioned. Rosacea affects both sexes, but is almost three times more common in women. It is commonly found in people between the ages of 30 and 50, and is more common in Caucasians.
Rosacea typically begins as redness on the central face across the cheeks, nose, or forehead, but can also less commonly affect the neck, chest, ears, and scalp. In some cases, additional signs, such as semipermanent redness, dilation of superficial blood vessels on the face, red domed papules (small bumps) and pustules, red gritty eyes, burning and stinging sensations, and in some advanced cases, a red lobulated nose (rhinophyma), may develop.
