Rosacea is a common but poorly understood long-term skin condition that mainly affects the face.
It can be controlled to some degree with long-term treatment, but sometimes the changes in physical appearance can have a significant psychological impact.
The exact cause of rosacea is unknown, although a number of possible factors have been suggested, including abnormalities in the blood vessels of the face and a reaction to microscopic mites commonly found on the face.
Although they’re not thought to be direct causes of the condition, several triggers have been identified that may make rosacea worse.
- Exposure to sunlight
- Strenuous exercise
- Hot or cold weather
- Hot drinks
- Alcohol and caffeine
- Certain foods, such as spicy foods
