Aging effects, such as facial flatness, increased tissue laxity, and soft tissue descent and deflation, contribute to midface deficiency.


To evaluate whether large gel particle hyaluronic acid with lidocaine (LGP-HAL) is more effective in the treatment of midface deficiencies than no treatment.


Subjects with mild to substantial loss of midface fullness were randomized 3:1 to LGP-HAL (Restylane Lyft; Galderma Laboratories, L.P., Fort Worth, TX) or no treatment. Treatment success was defined as at least 1-grade improvement in Medicis Midface Volume Scale (MMVS) on each side of the face at 8 weeks as assessed by a blinded evaluator. Secondary efficacy end points included MMVS score, global aesthetic improvement, and subject satisfaction.


Significantly greater percent of subjects achieved treatment success in the LGP-HAL group compared to no treatment at all time points through Month 12 (p < .001). One year after initial treatment, 85% of subjects still had a global aesthetic improvement assessed by the treating investigator. Subject satisfaction demonstrated that LGP-HAL improved the aesthetic appearance of the midface. Most reported adverse events (80%) were mild in severity.


The LGP-HAL treatment is well tolerated and provides significant improvement up to 12 months for the correction of midface deficiencies.
