Background: Hyaluronic acid (HA) filler longevity has been studied for wrinkles. However, its long-term use for treating atrophic facial scars has not yet been analyzed in long-term prospective studies.
Objective: Analyze the safety and duration of a HA filler for the use in atrophic scars.
Background: The long-term efficacy and safety of hyaluronic acid fillers injected into the neck have yet to be analyzed in a prospective trial in the United States.
Objective: Analyze the long-term efficacy and safety of a hyaluronic acid filler for static horizontal neck rhytids.
Materials And Methods: Twenty-six subjects were enrolled in the study.
Background: Hyaluronic acid fillers have been studied extensively for facial wrinkles; however, their efficacy for atrophic facial scars has yet to be analyzed in a prospective placebo-controlled study.
Objective: To analyze the efficacy and safety of a hyaluronic acid filler for atrophic facial scars.
Methods & Materials: Fifteen subjects were randomized to receive up to 1 ml of VYC-17.
Background: Hyaluronic acid (HA) fillers have been studied extensively on the face; however, their safety and efficacy on the neck has not yet been evaluated in a prospective trial in the United States.
Objective: Analyze the efficacy and safety of a HA filler for static horizontal neck rhytides using either a cannula or needle.
Materials And Methods: Twenty-six subjects were randomized to receive up to 1 mL of the HA filler Restylane Refyne (HARR, n = 20) or saline (n = 6) using a cannula on one side and a needle on the other with optional repeat treatment.
