Expert Consensus on Injection Technique and Area-Specific Recommendations for the Hyaluronic Acid Dermal Filler VYC-12L to Treat Fine Cutaneous Lines.

[BACKGROUND] VYC-12L is a hyaluronic acid (HA) injectable gel designed to treat fine cutaneous lines and improve skin quality attributes such as hydration and elasticity.

[OBJECTIVE] Expert consensus was sought on VYC-12L injection technique and primary treatment target areas.

[METHODS] A multinational group of aesthetic medicine clinicians (n = 128) attended product training and each identified ~10 patients for VYC-12L. After treating their first and last patients, the clinicians completed a survey on preferred injection methodology/technique, including injection angle, volume, and spacing. An expert panel (n = 12) discussed survey results and their clinical experiences to obtain consensus on VYC-12L technique and appropriate treatment areas.

[RESULTS] Recommendations included micro-depot injections of VYC-12L into the deep dermis with a 32G ½ inch needle inserted at <45º to the skin, spaced 0.5‒1.0 cm apart, with 0.01‒0.05 mL volume per injection (full-face total volume: ~2 mL). Recommended primary treatment areas were the malar, perioral, neck, and décolletage regions. Injection techniques for different treatment areas/demographic characteristics were similar, with some variability in treatment approach. Patient selection criteria, pre- and post-treatment guidelines, and managing patient expectations are important components of treatment.

[CONCLUSION] These consensus recommendations may assist clinicians in optimizing the treatment of fine lines with VYC-12L.
