I was reading some papers comparing Calcium Hydroxylapatite (Radiesse) and polycaprolactone (Ellanse) and the conclusion is that the latter last much longer, with added permanent results, due to the longer polymer chain.

In other words the final total permanent gain is 3 % of the original shot gain.
Thanks for that info! Did they say anything about the relative firmness when Erect?
