ABSTRACT Background Mesotherapy, a widely utilized minimally invasive cosmetic procedure, carries potential risks of adverse reactions due to non‐standardized protocols and overuse. Delayed granulomatous reactions represent a chronic complication, imposing significant physical and psychological burdens on patients. Objective This case series aims to evaluate the efficacy and safety of tofacitinib in managing non‐infectious granulomatous reactions following mesotherapy. Methods This retrospective analysis included six patients diagnosed with non‐infectious granulomatous reactions post‐mesotherapy, treated at Peking Union Medical College Hospital between October 2021 and April 2025. All patients received oral tofacitinib. Clinical outcomes, treatment regimens, and safety profiles were assessed. Results All six patients demonstrated significant improvement in skin lesion severity, with no treatment‐related adverse events observed during follow‐up. Conclusion Oral tofacitinib exhibits promising clinical efficacy and a favorable safety profile for non‐infectious granulomatous reactions induced by mesotherapy, positioning it as a viable therapeutic option during the inflammatory phase.
