Primary Outcome Measures:
  • The incidence of device related adverse events [ Time Frame: Assessed at treatment, suture removal, Months 1, 3, 6, 9 and 12 ] [ Designated as safety issue: Yes ]
    Device safety is defined as the incidence of device related adverse events.

  • Recurrence of keloid post scar excision [ Time Frame: Assessed at 1, 3, 6, 9 and 12 months ] [ Designated as safety issue: No ]
    Proportion of subjects with recurrence of keloid scar post excision defined as the presence of scar tissue volume >0.3cc

Secondary Outcome Measures:
  • Patient and Observer Scar Assessment Scale (POSAS) [ Time Frame: Assessed at Pre-treatment, Months 1, 3, 6, 9 and 12 ] [ Designated as safety issue: No ]
  • Subject Dermatology Life Quality Index (DLQI) [ Time Frame: Assessed at Pre-treatment, Months 1, 3, 6, 9 and 12 ] [ Designated as safety issue: No ]
  • Device Performance Evaluation [ Time Frame: Assessed at Day 1 ] [ Designated as safety issue: No ]
    Questions related to packaging integrity and successful administration of product as assessed by the Principal Investigator.
