Summary:

      This double-blind study has two parts for each subject (same population):

      Part A: initial treatment in Lateral Canthal Lines (LCL) (placebo-controlled):

        -  To assess the efficacy and safety of Azzalure® compared to placebo in the improvement of
           moderate to severe LCLs.

        -  To assess the subjects' level of satisfaction with the appearance of their LCLs compared
           to placebo.

      Part B: repeated treatment in LCL with or without Glabellar Lines (GL) (active treatment, up
      to 1 year):

        -  To assess safety of Azzalure® following repeated administration in the improvement of
           moderate to severe LCLs.

        -  To assess the safety of Azzalure® when used concomitantly for improvement of moderate to
           severe LCLs and GLs.

        -  To assess the subjects' level of satisfaction with the appearance of their LCLs.
