I've been following Evolence and I do not think it will prove to be popular. Since the active ingredient is derived from an animal, there are risks of reaction to the collagen (approximately 3% from what I recall) which is relatively high. That's 1 in 30 patients. That in addition to individual testing on the patient before they use the product is not appealing. I think what we'll see is Juvederm Ultra Plus and Perlane, the two longer-lasting hyaluronic acid injectable fillers, maintaining their lions shares of the market. Even a plastic surgery forum such as this reiterates these as being favorites among the fillers. The only thing I see knocking them off the top is another hyaluronic acid based filler which lasts longer than 6 to 9 months.
“One popular new plastic surgery technique is called lip grafting, or "fat recycling" wherein fat cells are removed from one part of your body that is too large, such as your buttocks, and injected into your lips; people will then be literally kissing ass.”
