Quite frankly there is no "proven method" as of yet, although on paper/in theory one could conceivably attain gains through low-volume injections of
HA (and NO other filler of ANY TYPE).
The problem with glans enhancement is that the area being enlarged also happens to present the most risks anatomically, hence why we're limited to
HA. As suggested in this thread, manual PE exercise techniques like
Clamping, and edging/ballooning can temporarily give your glans a circumferential boost.
I know in my conversations with
Avanti Derma &
Morganstern Rejuvall, if any viable method (outside the only one available) presents itself as an efficacious alternative, it will definitely be considered.
