Available hyaluronic acid dermal fillers have unique biophysical properties that influence their clinical utility, longevity, and aesthetic outcomes.OBJECTIVE
To evaluate the effectiveness and durability of a cohesive polydensified matrix hyaluronic acid dermal filler (CPM-HA) for the treatment of etched-in fine facial lines.MATERIALS AND METHODS
Subjects with etched-in fine lines of the forehead, cutaneous lip, melolabial folds, nasolabial folds, and/or radial cheek received treatment with CPM-HA mixed with lidocaine and epinephrine, with an optional touch-up treatment at Week 2, if deemed necessary. Response to treatment (as measured by the Merz Aesthetics Scales, Lemperle Facial Wrinkle Scales, and subject self-assessment) and safety/tolerability were monitored over the course of 26 weeks.RESULTS
Thirty-one subjects received treatment with CPM-HA to 1 or more facial areas. All 5 treatment areas showed clinically meaningful and statistically significant improvements in average clinician rating scale scores at all study visits (p < .001 vs baseline). Most subjects reported maintained improvement from baseline of 50% or more throughout the 26-week study. Injection site reactions were mild and resolved without intervention.CONCLUSION
Cohesive polydensified matrix hyaluronic acid dermal filler treatment was well tolerated and provided consistent and durable improvement in the appearance of a diverse range of etched-in fine facial lines.
