Buy a full syringe but only use half and save the other half for another time?

Some physicians save syringes and others don't.  There are studies that show the material has no increased risk of infection if used multiple times.  This is not the recommendation of the companies making the fillers.  I suggest you trust your treating physician.  Best, Dr. Emer.

It is unsafe to store used syringes of filler for several reasons:Risk of injection for youRisk of having someone else's syringe used on you if there was an errorRisk to staff and injector from syringes and needles being manipulatedFor these reasons, I will not "bank" filler for patients. It is just not worth the risk to you. If you can purchase a half syringe that will be much safer for you.I hope this information is helpful for you.Stephen Weber MD, FACSDenver Facial Plastic Surgeon

Restylane comes in half syringe sizes so this is the better alternative for you   It is not customary to save half used syringes
