[Expert consensus in Southwest China on the application of botulinum toxin type A in upper and mid-facial aesthetics].

Abstract

This consensus systematically addresses the unique facial anatomical and aging characteristics of the population in Southwest China and systematically proposes an individualized injection protocol for botulinum toxin type A (BONT/A) for upper and mid-face aesthetic treatments. The protocol was tailored to the skeletal and muscular features of this regional group and incorporates precise injection techniques, dosage recommendations, and depth guidance for key upper facial areas, such as forehead lines, glabellar lines, crow's feet, nasal wrinkles, and temporalis muscle. In addition, it outlines peri‑injection assessment procedures, combined treatment strategies, and the management of adverse reactions. The aims are to provide clinicians with standardized operational guidance that aligns with regional characteristics and to enhance the safety, precision, and aesthetic outcomes of treatment.
