(CALGARY, Canada) – A new study has revealed possible long-term consequences of using Botox, reports the New York Daily News.
Researchers at the University of Calgary in Canada injected rabbits with the substance and found that it could spread through the body.
"We were surprised by the degree of muscle loss and atrophy in the limb that was not injected with the Botulinum toxin," said lead study author Rafael Fortuna. "I think it’s fair to say that the paper raises some important questions about the long-term therapeutic use of Botox, especially with children and adolescents."
The long-term effects of Botox have not been evaluated by the FDA, although it was approved for cosmetic use in 2002.
Approximatly 2.5 million Americans used Botox injections last year.
