title: An observational study of a 24 mg/mL hyaluronic acid with pre-incorporated lidocaine for lip definition and enhancement.
abstract: BACKGROUND
  Lip enhancement using fillers improves appearance by increasing fullness, enhancing lip definition, and reducing fine lines and wrinkles around the lips.
  
  
  OBJECTIVE
  To investigate a 24 mg/mL hyaluronic acid (HA) with pre-incorporated lidocaine gel for lip definition and enhancement, medium-deep lines, and oral commissures.
  
  
  METHODS
  Eleven injectors enrolled 57 patients (96% women; aged 18-60+ years) requesting lip definition and enhancement. Prospective data were captured using an Injector Patient Case Assessment Form and Patient Questionnaire.
  
  
  RESULTS
  Ninety-five percent of injectors found the gel 'very easy' to inject, with 82% finding it "very easy" to massage/sculpt. Combined injector and patient pain assessment revealed little treatment discomfort. Ninety-nine percent of injectors reported improved aesthetic effect compared to baseline. Post-treatment, 99% of injectors rated the lips as "smooth." All patients reported improved lip appearance and smoothness, and 96% were satisfied with the treatment experience. Compared to previous lip treatment, all patients reported their lips felt better, 57% rated the aesthetic effect as better, and 84% rated satisfaction as better than previous treatments. Ninety-eight percent of patients and injectors would recommend treatment to others.
  
  
  CONCLUSIONS
  High levels of injector and patient satisfaction were found after use of this 24 mg/mL HA with pre-incorporated lidocaine for lip definition and enhancement.
