Optimizing Facial Aesthetics: Sequential Application of Botulinum Toxin A and Dermal Fillers for Enhanced Results.
Constance Hall
PMID 38166310WHAT IT FOUND
Injecting botulinum toxin to relax facial muscles before adding dermal fillers may reduce filler migration and bruising while requiring less product.
This sequencing allows for more precise contouring and improved patient satisfaction compared to simultaneous application.
Key findings
01Sequential application of botulinum toxin A before dermal fillers reduces muscle interference, minimizing filler migration and allowing for precise sculpting.
02Pre-treatment with botulinum toxin A does not increase the risk of adverse events and may reduce bruising and swelling due to decreased muscle movement.
03Allowing 2-4 weeks for botulinum toxin effects to settle before injecting fillers often results in satisfactory outcomes with less filler volume required.

What it does not show
This is a narrative review, not a randomized controlled trial, so it relies on existing literature and expert opinion rather than new primary data. The review does not provide specific quantitative data on effect sizes, complication rates, or patient satisfaction scores from a controlled study. The cited evidence is from a limited number of studies and general clinical experience, lacking rigorous comparative analysis against simultaneous treatment protocols.
Declared interests
The author reports no conflicts of interest.
The easy way to misread this
Do not interpret this as high-level evidence proving superior outcomes. This is a narrative review synthesizing existing literature and expert opinion, not a controlled trial, so the benefits described are theoretical or based on uncontrolled observations.
