This Is a very interesting and informative article that I believe it should clear out all myths about Toxins. A must read article!
- Myth 1: Different Products Yield Different Results
- Myth 2: Diffusion Profiles Differ Between BoNT-A Formulations
- Myth 3: Protein Load is Clinically Important.
- Myth 4: Neutralizing Antibodies Are an Important Determinant of Treatment Failure in Aesthetic Indications
- Myth 5: Reconstitution Solution Matters
- Myth 6: The Volume of Injection Matters
- Myth 7: Post-Treatment Protocols Are Well Supported by Clinical Evidence
Keywords : Botox, Neurotoxins
OBJECTIVE
Numerous myths and misconceptions regarding the use of BoNT-A for aesthetic indications have arisen, which this review aims to lay to rest.
MATERIALS AND METHODS
This review assesses evidence for and against each of the most common myths regarding BoNT use in aesthetics.
RESULTS
BoNT-A neurotoxin/protein complexes are irrelevant to the toxin’s therapeutic/aesthetic indications. BoNT-A neurotoxin/protein complexes do not influence movement from injection site or immunogenicity. Any relationship between neutralizing antibody formation and clinical response is complex and clinicians should consider other factors that may induce an apparent loss of clinical response. Diffusion appears predominantly, perhaps exclusively, dose dependent. Careful placement and correct dosing optimizes likelihood of good outcomes. Manufacturers recommend reconstitution of products with sterile non preserved saline. However, compelling evidence suggests that reconstitution using preserved saline dramatically improves patient comfort without compromising efficacy. Several post-treatment instructions/restrictions are widely used despite the lack of evidence, but muscle activity after injection may be beneficial. Cooling the treatment area might hinder BoNT-A translocation and should probably be abandoned.
CONCLUSION
The existing evidence suggests that experienced users should achieve equivalent results regardless of BoNT-A formulation.
