Summary
Despite the wealth of information in the literature regarding the cosmetic applications of
botulinum type A toxin (BoNT-A), and the widespread use of the BoNT-A for cosmetic
applications, the number of randomised, controlled clinical trials is small. Much of the
published information is based on open-label studies or anecdotal data. Of the robust trial
data that is available, the vast majority relates to the treatment of glabellar lines, and
there is little data available regarding the use of BoNT-A in lateral canthal lines. This
study aims to determine the optimum dose for the use of BoNT-A in this area.
