This article examines how aesthetic surgery outcomes are defined, measured, and interpreted in clinical practice, with a focus on strengthening evidence-based assessment in cosmetic procedures. The authors discuss the limitations of current subjective evaluations, highlight both objective and patient-reported outcome measures, and propose strategies to better capture meaningful results that reflect both surgical quality and patient satisfaction. Their analysis underscores the value of standardized outcome metrics to advance scientific rigor and ensure high standards of care in aesthetic surgery.
