Introduction:
Submental fullness (SMF), or the double chin, is a condition regarded as undesirable. Many treatment modalities are available for SMF reduction, such as energy-based devices, injection lipolysis, or surgery. However, of minimal invasive modalities, hyaluronic acid (HA) injection has not been explored for possible SMF treatment.
Case Report:
A 52-year-old East Asian female patient with prominent SMF underwent HA filler injection. Aside from marked reduction of SMF prominence, an improvement of sagging over her cheeks and jawline, and a general improvement to facial aging signs was noted.
Conclusion:
HA filler injections for SMF offer an instant, zero downtime, and safe alternative, and can be considered in patients who wish to simultaneously achieve improvement in other facial areas.
