Rosacea is a common, chronic (long-term) inflammatory skin condition that mostly affects your face (cheeks, nose, chin and forehead).
It mainly affects fair-skinned people, especially people of Celtic or Northern European origin, but may occur in any skin type. It affects about 5% of the world’s population. It can start in childhood, but most often appears between 30 and 60 years of age.
Rosacea isn’t contagious so you can’t pass it on to somebody else.
Symptoms include facial flushing, redness, acne-like spots, small visible blood vessels on your face, thickening of your skin, and eye problems such as dry eyes and sore eyelids.
