Evolence is a porcine (Pig) derived collagen product used to provide soft tissue augmentation. Although no allergic reactions have been reported with Evolence, there have been several reports of nodule formation in the lips.
In my Raleigh, North Carolina Plastic surgery practice we do NOT use Evolence. I am more comfortable using Juvederm, Restylane, perlane or Prevelle Silk as a temporary filler and fat grafting for individuals seeking permanent results.
