causes of rosacea on face
Rosacea is a common and long-term skin condition that mainly affects a person's face. When rosacea first appears, the face may look flushed. Later symptoms include permanent redness, spots, visible blood vessels and a sensation of burning or tingling. Rosacea affects around one in 10 people to some extent, mostly among people with fair skin. The cause of rosacea is not known, although there are several different theories. One theory is that rosacea may be part of a more generalised disorder of the blood vessels.
