Neuropeptide May Play Role in Pain and Flushing
According to a study funded by the National Rosacea Society, researchers have found a potential connection between the nervous system and the redness and stinging of subtype 1 (erythematotelangiectatic) rosacea.
Drs. Ferda Cevikbas and Martin Steinhoff, University of California-San Francisco, noted that the flushed face of rosacea is often accompanied by stinging and burning, signs of nerve activation. They theorized this may signal a dysfunction in communication between the nerves and the vascular system.
