Nefertiti Lift Dosing
For a Nefertiti lift, the typical dose ranges from 40-50 units of onabotulinumtoxinA (Botox), distributed along the inferior border of the mandible and into the platysmal bands, though doses up to 125 units have been reported in clinical studies.
Evidence-Based Dosing
The original technique described by Levy used up to 20 units of onabotulinumtoxinA (Vistabel/Botox) in 130 patients with high satisfaction and low adverse effects 1. However, more recent clinical research demonstrates higher doses are commonly used in practice.
A 2017 clinical trial of 30 patients used a mean dose of 124.9 units of abobotulinumtoxinA per patient, injected along the inferior border of the mandible and into the platysmal bands 2. This study showed statistically significant improvement in platysmal bands both at rest and with maximal tension, with 93.3% of investigators and patients rating overall results as improved.
Practical Dosing Algorithm
Distribution pattern:
- Inferior mandibular border: 20-40 units total (distributed in small aliquots of 2-4 units per injection site along the jawline)
- Platysmal bands: 20-40 units total (injected directly into visible bands when present)
- Total typical dose: 40-80 units for onabotulinumtoxinA
Important conversion note: If using abobotulinumtoxinA (Dysport), multiply the onabotulinumtoxinA dose by approximately 2.5-3x due to different potency ratios between formulations.
Patient Selection Considerations
The Nefertiti lift works best in:
- Younger patients with platysma muscle hyperactivity
- Patients with retained skin elasticity
- Those with lower baseline severity scores for jowls and neck aging 2
Patients with significant skin laxity, heavy jowls, or advanced neck aging are less likely to achieve satisfactory results and should be counseled accordingly.
Treatment Technique
Inject along the inferior border of the mandible in a linear pattern, spacing injections approximately 1-1.5 cm apart. When platysmal bands are visible, inject directly into the bands. The goal is to relax the downward pull of the platysma muscle, allowing the skin to "drape" upward and create a lifting effect 1.
Expected Outcomes and Duration
Effects typically become visible at 2-4 weeks post-injection, with peak results at 4 weeks. Duration of effect is approximately 3-4 months, similar to other botulinum toxin applications in the lower face 2.
Safety Profile
The procedure has a favorable safety profile when proper technique and dosing are used. The lower face muscles show greater and more durable response to botulinum toxin compared to upper face muscles, so conservative initial dosing is prudent 1. Common adverse effects are minor and transient, with no serious complications reported in the published studies 1, 2.
Critical caveat: Avoid excessive dosing or improper injection depth, as this can lead to unwanted effects on facial expression or swallowing muscles. Start conservatively in treatment-naive patients and adjust subsequent doses based on response.
