Consensus on the Cosmetic Use of a Novel Botulinum Neurotoxin Type A Product (NEWLUX) for Facial Expression Muscles: 2024 Guidelines and Discussions by Korean Experts.

[BACKGROUND] Botulinum neurotoxin type A (BoNTA) is widely used in aesthetic facial rejuvenation medicine. The exponential growth in using BoNTA for cosmetic purposes in Korea necessitates an update to the existing practice guidelines, building upon the consensus established by Korean experts in 2013.

[AIMS] This work aims to provide an updated Korean consensus guideline for the safe and effective use of a novel BoNTA product (NEWLUX) for facial expression muscles.

[METHODS] A panel of ten Korean experts in dermatology, plastic surgery, aesthetic medicine, and clinical anatomy convened in February 2024. They reviewed prior guidelines, including the 2013 Korean consensus, and shared their expertise on dosage, injection techniques, and potential complications associated with the use of the novel BoNTA product for facial expression muscles. The recommendations aimed to guide the best practices of the average aesthetic healthcare professional.

[RESULTS] The panel reached a consensus on various aspects of using the BoNTA product, including recommended injection sites, dosages, and techniques for different aesthetic conditions caused by facial expression muscles. The resulting guideline emphasizes safety and efficacy, with recommendations based on the collective experience of the expert panel.

[CONCLUSION] This updated consensus guideline provides practical recommendations from Korean experts on the use of the novel BoNTA product for facial expression muscles. The guidelines will ensure safe and effective treatments while reflecting the latest advancements in the field.
