The results of a new study published in Dermatologic Surgery has indicated full-facial volume restoration can be sustained for more than 18 months in patients who receive a hyaluronic filler (HA) with lidocaine.

The results of a new study published in Dermatologic Surgery has indicated full-facial volume restoration can be sustained for more than 18 months in patients who receive a hyaluronic filler (HA) with lidocaine.

The study looked at long-term full-facial volume restoration in 60 patients between February 2012 and March 2013 in Brazil, using the HA filler with lidocaine.

Researchers studied patients with a score of at least 2 (visible depression or decent) on the 4-point volume loss scale for the full face, and at least two affected indications, including chin, temporal areas, jawline, cheeks, cheekbones and nasolabial folds.

The patients were treated with 20mg/mL of hyaluronic acid and 3mg/mL of lidocaine, with injections given in two to six indications and an optional touch-up three weeks later.

Most patients had three of four indications injected (71.6%), with the cheekbones being the most common place for injections (96.7%).

The results at 18 months suggested at least a 1-grade improvement in the volume loss scale for the full-face. For all indications, more than 60% of the volume gained at three weeks was sustained at 18 months.

The researchers said, volume restoration of the ageing face was “Sustained over 18 months for the full-face for all indications, particularly in the mid-face area, as demonstrated by subjected volume restoration assessments and objective 3-D imaging assessments.”
