Canthal lines
Brief 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.
Interventions
During part A, Azzalure will be administered at Baseline 60 Speywood units at canthal lines and compared with placebo.

Inclusion criteria
* Male or female subjects, 18 to 65 years of age (Screening visit), * Moderate or severe (grade 2 or 3, Hund 2006) Lateral Canthal Lines at maximum smile determined by investigator at screening and baseline * Mild to severe (grade 1, 2 or 3, Hund 2006) Lateral Canthal Lines at rest determined by investigator at screening and baseline * The subject is a female of childbearing potential and has a negative urine pregnancy test (UPT) at screening and baseline * Subjects who are not satisfied with their appearance at screening and baseline * The subject is willing and able to comply with the requirements of the protocol and agree to adhere to the visit schedule, concomitant therapy prohibitions and must be compliant to the study instruction. * The subject agrees to participate in the study, verified by dating and signing an approved written Informed Consent Form (ICF) and Photography Consent Form (PCF) (selected sites only if applicable) at the enrolment visit before any study procedures at screening
Exclusion criteria

| Number of Responders on the Severity of Lateral Canthal Lines at Maximum Smile. | Week 4 | A positive response (responder) is defined as a grade of 0 or 1 (none or mild), as assessed by the investigator. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Number of Participants Satisfied With the Appearance of Their Lateral Canthal Lines | Week 4 | Participants were asked to assess their degree of satisfaction with the appearance of their lateral canthal lines using a 4-point scale with the grades Very satisfied, Satisfied, Dissatisfied, and Very dissatisfied. A participant is considered satisfied if he/she answers Very satisfied or Satisfied. |
