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.

Chicken or Egg? Debate Continues

Demodex mites, the microscopic parasites that are normal inhabitants of facial skin, have long raised the question, "Which comes first, Demodex or rosacea?" as medical experts debate whether their increased numbers on rosacea patients are a cause or a result of the disorder. Now there may be some evidence that the "chicken" — Demodex mites — and not the "egg" comes first, according to a recent scientific report.
