Hyaluronic Acid Soft Tissue Filler for the Treatment of The Hypoplastic Chin: An Observational Study.

[BACKGROUND] The hypoplastic chin is associated with facial unattractiveness.

[OBJECTIVE] To evaluate safety and efficacy of JUVÉDERM Voluma XC Injectable Gel (hyaluronic acid filler, HAF) for treatment of hypoplastic chin.

[METHODS] This was a one-year, open-label, single-center study.

[RESULTS] Thirty subjects received HAF injections of which 24 subjects (80%) completed the study. Mean facial angle significantly improved at all time points compared with baseline, improving by 1.83° (95% confidence interval, 0.91, 2.75; p < .001) at 12 months. Subject satisfaction with lower face and jawline increased significantly for all FACE-Q questions and time points compared with baseline (p < .05). Subject satisfaction with overall facial appearance, and percentage of subjects "not bothered" by area under chin increased significantly for most FACE-Q questions and time points compared with baseline (p < .05).

[CONCLUSION] In this completed one-year study, HAF injection for hypoplastic chin was safe and accompanied by significant improvement in facial angle, measures of subject satisfaction, and GAIS.
