Voluma vs Versa
The studies to obtain FDA approval for Voluma were done in the cheek and for Revanesse Versa in the nasolabial lines but I think we can infer that the fillers are likely to last roughly the same amount of time when use in the penis.
This is from the package insert for both medications:
Juvéderm Voluma™ Xc
-Voluma is documented to provide significant and sustained benefits up to 24 months post-treatment. This demonstrates that it can maintain good correction for up to two years.
- 86.6% improvement at 9 months.
- 85.2% improvement at 12 months.
- 71.5% improvement at 18 months.
- 67.1% improvement at 24 months.
Revanesse® Versa™
- Limited Long-Term Effectiveness Without Retreatments: Revanesse® Versa™ has shown sustained effectiveness up to one year post-initial treatment but requires a retreatment at 6 months to achieve this.
-The retreatment study for Revanesse® Versa™ showed: Continuous improvement up to 52 weeks, but only in patients who were retreated at 6 months.
Voluma is much longer lasting so I would calculate that in to your considerations
