Abstract

Objective The aim of this investigation was to assess the effectiveness of a non-cross-linked hyaluronic acid based soft-tissue filler in the correction of lateral canthal lines and periorbital lines. Material and methods A total of 59 female Caucasian patients with a mean age of 52.6 +/- 9.0 years were enrolled in this prospective open-label, multicentre study and received intradermal injections of a soft-tissue filler at baseline, after 3 and 6 weeks. Aesthetic improvement and patient satisfaction, skin hydration, skin firmness and skin elasticity, as well as adverse events were assessed at 3, 6, 8, 12 and 16 weeks. Results At baseline, the lateral canthal skin firmness was 0.206 +/- 0.07 mm and increased after 8 weeks to 0.087 +/- 0.08 mm with p < 0.001, while the perioral skin firmness was 0.205 +/- 0.09 mm and increased after 8 weeks to 0.116 +/- 0.08 mm with p < 0.001. Increases in skin hydration were observed after 8 weeks in both areas, however, did not reach statistical significance at any point. At week 8, 12 and 16 a majority (93.1%, 91.1% and 73.7% respectively) of the patients stated that they were 'satisfied' or 'very satisfied' with the treatment. Conclusion Overall, the skin firmness and skin visco-elasticity showed significant increases in the lateral canthal and perioral region. Moreover, albeit not statistically significant, skin hydration increased in both areas after 8 weeks. The procedure has been shown to be safe and satisfactory for the treated patients;however, emergence of oral herpes should be added to the safety profile of intradermally applied hyaluronic acid treatments.
