Treatment of midface deficiencies with Restylane Lyft was effective and well-tolerated with results lasting up to 12 months, according to study results.

Researchers conducted a 15-month trial of 200 patients with mild-to-substantial loss of midface fullness (92% women; mean age, 52.9 years) who were randomly assigned to Restylane Lift (large gel particle hyaluronic acid with lidocaine [LGP-HAL], Galderma Laboratories; n = 150 patients) or no treatment (control; n = 50).

Improvement of at least one grade in the Medicis Midface Volume Scale (MMVS) on each side of the face at 8 weeks, as determined by a blinded evaluator, was used to define treatment success.  MMVS score, global aesthetic improvement and patient satisfaction were secondary endpoints.

There were 188 patients (94%) who completed the study. In the LGP-HAL group, LGP-HAL total mean volume injected for initial treatment was 6.23 mL and 3.8 mL at a 12-month retreatment. An optional touch-up injection could be performed at 2 weeks after baseline and 12 months for optional correction. Patients in the control cohort received their first treatment of LGP-HAL at 12 months.

There were 89% of patients in the LGP-HAL cohort who were MMVS responders, with right and left midface combined, compared with 16% of control patients at week 8 (P < .001). MMVS ratings at time points through 12 months for the right and left midface combined and separately, found the LGP-HAL treatment significantly better than no treatment (P < .001).

Most of the patients in the LGP-HAL cohort achieved at least a 1-grade improvement throughout 12 months, with additional treatment at 12 months resulting in increased augmentation.

There were 85% of patients who continued to have a global aesthetic improvement assessed by the treating investigator at 12 months after initial treatment.

Patients in the LGP-HAL cohort reported higher satisfaction beginning with week 4 through 12 months.

There were 49% of patients reporting adverse events at initial treatments and 29% reporting adverse events at second treatment at 12 months, with 80% of the adverse events considered mild in severity.

“LGP-HAL is effective for midface augmentation and correction of midface contour deficiencies and provides clinically meaningful visible aesthetic results for at least 12 months with a very good safety profile,” the researchers concluded.  – by Bruce Thiel
