Paper Abstract
The effects of caffeine and coffee, agents widely alleged to provoke flushing in patients with erythematotelangiectatic rosacea, were investigated. Neither caffeine nor coffee at 22 degrees C led to flushing reactions. Both coffee at 60 degrees C and water at 60 degrees C led to flushing reactions with similar temporal characteristics and of similar intensities. It is concluded that the active agent causing flushing in coffee at 60 degrees C is heat, not caffeine.
