Could Botox Injections Impact Surrounding Muscles?
By NewBeauty Editors |
If you've ever wondered about the potential consequences of repeated Botox use, you're not alone. A new study released by the Faculty of Kinesiology at the University of Calgary is questioning whether or not botulinum toxin type A injections (Botox and Dysport) can cause surrounding muscles to soften, even though they're not directly injected.
Though the study was more interested in the after affects of using the drug therapeutically, such as using it to reduce muscle spasms, researchers state that the results should be relevant for all its uses. The report found that animals injected with the Canadian version of Botox experienced weakness in muscles throughout the body despite the fact that many of the muscles were not located near the injection site. Muscle atrophy and a decrease of contractile tissues in non-injected areas was also noted.
Now, this is yet to be substantiated and may depend on the injection site and the volume and dosage of the material, but the study is raising some important questions about long-term use of the drug.
