Background and Objectives
The use of botulinum toxin injections in cosmetic procedures is widely practiced in aesthetic medicine. Recently, various toxin products have been developed and are appearing in the medical market. We sought to document what clinicians consider important when selecting a toxin product, excluding price, which was found to be the most important factor in our previous study.
Materials and Methods
At the conference of the Korean Association for Laser, Dermatology, and Trichology (KALDAT) held on July 26, 2020, we conducted a web-based realtime survey to investigate the bases for clinicians’ decisions on botulinum toxin products, particularly what clinicians consider most important when selecting toxin products. In addition, we examined whether the purpose of the procedure affected their choices.
Results
When clinicians chose a botulinum toxin product, the second most important factor after price was the stability of the toxin. This was the same for procedures to improve wrinkles and to reduce muscle volume.
Conclusion
The stability of toxin products is an essential aspect to achieving consistent and predictable results, and as such, clinicians consider it very important when selecting toxin products. Companies that are producing or preparing to develop botulinum toxin products should pay attention to securing and maintaining product stability.
