Combining fillers and neuromodulators in the same syringe

摘要

In reviewing literature on combination techniques for facial rejuvenation, we came across Dr. Kenner's September 2010 article entitled "Hyaluronic Acid Filler and Botulinum Neurotoxin Delivered Simultaneously in the Same Syringe for Effective and Convenient Combination Aesthetic Rejuvenation Therapy." The article elaborates Dr. Kenner's technique of mixing HA filler, lidocaine, epinephrine, and neuromodulator using a syringe and female-to-female connector with "10 back and forth mixings to ensure even distribution." We were surprised that there has not been editorial response to this paper as it presents several concerns.
