Cosmetic Botulinum Toxin A to the Platysma

The presentation discusses the role of the platysma muscle, often misunderstood as merely a neck muscle, highlighting its significant influence on the lower face and neck appearance. It examines the Nefertiti technique introduced by Phil Levy in 2007, which involves targeting the mandible area of the platysma with botulinum toxin A (20 units per side) to enhance jawline aesthetics and reduce neck sagging. The speaker shares personal experiences and patient results, illustrating how proper injection techniques can effectively alter the muscle's function. Emphasizing the importance of understanding facial anatomy, the talk mentions how injecting the platysma can also affect other facial regions, suggesting a correlation between weakening the platysma and improved mid-face appearance. The speaker recommends this technique as a popular treatment that pairs well with other aesthetic procedures, ultimately advocating for a broader recognition of the platysma as an active contributor to facial dynamics rather than just a muscle of the neck.
