Evaluation of Intradermal Injection of Botulinum Toxin A for Facial Lifting.

Intradermal botolinum toxin A (BTXA) is an advanced technique that emerged in response to the increased demand for noninvasive facial lifting and skin rejuvenation. We sought to evaluate the safety and efficacy of intradermal injections of BTXA for facial lifting. Twenty-five female patients with mild symmetrical facial skin laxity were enrolled in this study.
