Hi Sam, thank you for the question.
In a nut shell, yes 'botox' is safe.
Botulinum toxin type A has been used in medicine for over 25 years and for cosmetic reasons just over 20 years. A large number of people believe that the 'botox' used cosmetically and for medical reasons is the true toxin. This is not true as only one of the proteins that make up the whole toxin (7 proteins in total) is used, therefore the name Botulinum toxin type A. The proteins making up the toxin are named A, B, C, D, E, F, and G. So only the type A protein is used, and to complicate matters a little further the type A protein has a long and a short chain in its molecular make up. In Allergan's 'botox' only the long chain of the A protein is used.
'Botox' has FDA approval for use in children 2 years of age. When botox is used for Cerebral Palsy a 12 year old child will get 400 units in each leg making a total of 800 units in one setting. When one injects botox for cosmetic reasons in the frown, forehead and eye area a total of 60 to 100 units may be used. This is much lower than what is given for a 12 year old child and is definately considered a safe dosage for adults.
I hope this answers your question.
