Reuse Juvederm Syringe for Future Injections?

Here are 3 separate studies showing the safety of re-injecting unused filler in the same patient. The science says it is safe.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. 

It is not recommended to reuse syringes secondary to risk of contamination. It is recommended and most sterile to use the products in one treatment. This should provide more filling and a more complete treatment.

First and most important question, should someone be using Juvederm in the forehead.  I think that this is generally a poor choice.  While there may be some exceptions, there are better products to use in the forehead such as Botox and even surgery (brow lift).  As you now know, with a few exceptions, Juvederm is not good in the forehead.  Usually storing Juvederm is not even an issue because it's easy to find places the product will make a difference and you can easily use the full syringe.  When doing just a small little touch up, I have stored the product in a refrigerator for up to 6 months.  I know this is in contradiction to what the company recommends and most of the authors on realself answering this question.  However, I have done this at least 20 times and never had problems.  I think the patient should be allowed to make thier own decision on this, but have the option to keep it for 6 months.
