What Causes Rosacea?
The cause of this condition is not fully understood, but researchers suspect that rosacea may be caused by a combination of inflammatory proteins and peptides in the skin, rather than by bacteria. Most dermatologists now view rosacea as an inflammatory disease of the skin.
Although anyone can develop rosacea, it tends to be seen more often in people over 30 years of age with fair skin and light eye color.
Common triggers for flare-ups include seasonal weather conditions, emotional stress, exercise, alcohol consumption and spicy foods.
