Facial aging is characterized by volume loss and progressive hollowing of temples and cheeks. Biodegradable filler materials are preferred over nonabsorbable materials; of these, hyaluronic acid (HA) fillers are the most often used because of their favorable effectiveness and safety profile.
To confirm the safety and effectiveness of Cohesive Polydensified Matrix (CPM)-HA26 gel in the treatment of volume deficiency.
Subjects received up to 2 treatments in the temples and/or cheeks. A blinded investigator assessed improvement according to the Merz Temple Volume Scale (MTVS) and Merz Cheek Fullness Assessment Scale (MCFAS). Subjects were followed for 48 weeks after the last treatment.
In total, 87 healthy subjects were enrolled. The proportion of subjects achieving at least a 1-grade improvement on MTVS and/or MCFAS was above 70% for each (MTVS: Weeks 4, 24, and 48 = 95.4%, 94.2%, and 77.0%; MCFAS: Weeks 4, 24, and 48 = 92.3%, 83.1%, and 71.8%). Based on MTVS and MCFAS scores at Visit 5, improvement remained visible at up to 48 weeks. No treatment-related serious AEs occurred.
CPM-HA26 demonstrated both a favorable safety and effectiveness profile, with improvement in facial volume evident for up to 48 weeks. It was well tolerated and had a positive, long-lasting effect.
