Clinical and erythema-directed instrumental evaluation of papulopustular rosacea treated with topical ivermectin

Background: Ivermectin 1% cream is a new therapeutic topical option able to control mild/moderate papulopustular rosacea (PPR). Nontransient erythema from inflammatory lesions represents an important component of PPR often leading to patient emotional suffering, and digital photography equipped with RBX system enabling separation of red/brown skin color signatures is a useful tool for evaluation of erythema in patients affected by inflammatory dermatoses including rosacea. Colorimetry is also a sensitive technique for skin color analysis.
