Sustained efficacy and high patient satisfaction after cheek enhancement with a new hyaluronic acid dermal filler.

BACKGROUND

Increasing volume is an important part of facial rejuvenation since volume loss is common and typically age-related. HA E Volume is a moderately firm gel designed to be injected into the subcutaneous tissue for volume enhancement.

OBJECTIVE

To assess the efficacy, patient satisfaction, and safety fo HA E Volume in patients with bilateral volume loss of the cheeks.

MATERIALS AND METHODS

This was a multi-center, six-month, open-label study. Subjects received HA E in the cheeks at baseline, and a touch-up injection was optional three weeks later. Global aesthetic improvement, cheek thickness (caliper measurements),changes in volume using three-dimensional (3-D) photo analysis, adverse events and injection site reactions were evaluated at each visit. Optimal correction was defined as results obtained three weeks after last injection. A subject satisfaction questionnaire was performed three weeks after the last injection.

RESULTS

Investigators evaluated the great majority of subjects as much or very much improved in terms of aesthetic improvement of their cheeks at week 3 and at mounts 3 and 6 (89.3%, 90.9%, and 76.4%, respectively). After six months, 65.8 percent of the correction achieved at week 3 (optimal correction) was maintained in terms of cheek thickness (caliper assessments), confirmed by 67.7 percent of the volume maintained based on 3-D volume analyses. The majority of subjects (92.1%) were satisfied or very satisfied with their aesthetic outcome. A good tolerability profile was observed.

CONCLUSIONS

Treatment with HA E Volume in cheeks led to good aesthetic improvement, sustained results confirmed by caliper and 3-D volume assessments, and high subject satisfaction.
