TOPIC: HA Filler Types for Glans

I’m interested in having my glans increased. I’ve noticed while reading through the forums that that the most common filler used for the glans is Juvederm Ultra. My doctor mentioned Volbella mainly because of the cross-linking (longevity) and low amount of water uptake to reduce swelling, but I haven’t seen any physicians using it in the glans. Makes me a little nervous. Is this still a safe, proper filler for the glans? Any drawbacks?
