A new injection technique for wrinkle-fighting facial fillers that would ease discomfort and speed up recovery has been developed by scientists from UT Southwestern Medical Centre.
The new technique combines lidocaine with injections of facial fillers to instantly minimize the pain and allows plastic surgeons to begin injection procedures without waiting for traditional anesthesia to take effect.
Advertisement"People are more at ease and have far less discomfort," said Dr. Rod Rohrich, chairman of plastic surgery at UT Southwestern.
There is significant time savings in not having to wait for traditional dental block anesthesia to take hold, and the procedure is more pain-free with shorter recovery time.
The technique mixes 2 percent lidocaine with certain hyaluronic and other fillers such as Restylane or Radiesse, providing an immediate numbing effect as the filler is injected.
Dr. Rohrich, who has used the combination for more than two years, notes, "It's becoming more of the standard."
Some popular hyaluronic fillers, such as Prevelle and Hydrelle, are now beginning to include lidocaine as part of FDA approvals.
The study appears in journal Plastic and Reconstructive Surgery.
