Increased blood flow to the blood vessels of the face and increased numbers of blood vessels that are closer to the surface of the face are thought to be responsible for the redness and flushing associated with rosacea. Furthermore, vasodilatation, the normal response to hyperthermia, is thought to be more pronounced or exaggerated in those individuals with rosacea.
