The study, involving 118 patients with facial psoriasis, evaluated the effectiveness of the Facial Psoriasis Log-based Area and Severity Index (fPLASI) compared to the traditional Facial Psoriasis Area and Severity Index (fPASI) in measuring the severity of facial psoriasis after systemic treatments. The findings indicated that fPLASI was more sensitive in detecting changes in severity, showing greater percentage changes and aligning more closely with the Physician's Global Assessment than fPASI, which tended to underestimate improvements. A high correlation coefficient of 0.94 was observed between changes in fPASI and fPLASI scores, suggesting that fPLASI is a more valid and reliable method for assessing clinical improvement of facial psoriasis in clinical practice settings.
