For the first time, a new study from China shows that the presence of inflammatory bowel disease (IBD), a well-known comorbidity of rosacea, as well as its subtypes, Crohn’s disease (CD) and ulcerative colitis (UC), may lead to rosacea, according to the report published in the scientific journal Nature Scientific Reports.¹

A researcher in Germany has proposed a novel unifying theory that may explain the molecular origin of rosacea in terms of climate adaptation. He contends that the new concept may not only explain why the disorder’s known triggers can cause flare-ups, but is also consistent with known therapeutic activity against rosacea’s signs and symptoms.

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.

Medical scientists reported significant progress in uncovering the potential causes and other key aspects of rosacea during the National Rosacea Society's third annual research workshop, held in conjunction with the annual meeting of the Society for Investigative Dermatology. More than 130 researchers heard results of ongoing studies funded by the National Rosacea Society, and discussed the need for further scientific investigation into this highly prevalent disorder.
