New knowledge regarding rosacea’s pathology may explain why some newer treatment strategies appear effective, while pointing the way for additional approaches, according to an expert who spoke at the American Academy of Dermatology’s annual meeting.
Recent developments regarding acne and rosacea in skin of color include studies showing that combination topical products for acne appear safe in this population, and the fact that rosacea is perhaps more prevalent than many might expect.
Developing treatments for rosacea requires first understanding the many pathways that contribute to its development, says Richard L. Gallo, M.D., Ph.D. The current hypothesis regarding the pathology of rosacea is that “there are certain triggers that we hear about from our patients, or observe ourselves,” Dr. Gallo says. “Then there’s a response,” which includes vascular, inflammatory and histopathologic changes in the skin.
