Risks of Using a Stored Syringe of Juvederm?

Here are 3 separate studies showing the safety of re-injecting unused filler in the same patient. The science says it is safe...at least within 6 months of injection.Bellew SG, Carroll KC, Weiss MA, Weiss RA. Sterility of stored nonanimal, stabilized hyaluronic acid gel syringes after patient injection. J Am Acad Dermatol. 2005;52:988–90.Davis K, Bottone EJ, Lucas D, Lebwohl M. Sterility of refrigerated injectable collagen syringes after injection of patient. J Am Acad Dermatol. 1992;27:959–61. Culligan PJ, Koduri S, Heit MH, Rackley R, Thomson RB, Schwabe L, et al. The safety of reusing injectable collagen: A multicenter microbiological study. Int Urogynecol J Pelvic Floor Dysfunct. 2002;13:232–4.

I do not save any residual fillers as there is a risk of infection during storage once its been opened. Especially since you have kept it at room temperature, more bacteria might have grown. Delayed infections can occur after the placement of your product. Do not use your product.

Reusing previously injected Juvederm really depends on the physician. It is generally not recommended to do this practice. I never reuse previously used Juvederm. In my opinion, Juvederm is sterilized for one time use. Injecting Juvederm later only invites an increased risk of infection whlie it sits in the stored environment. No matter where you store it, the Juvederm will accumulate bacteria and when reinjected will only increase the risk of infection. I would be careful going to a physician that does this in my opinion.
Consulting a Board Certified Facial Plastic Surgeon would be something that I would recommend. We specialize in the face and are highly qualified to help you with this.
