Stay away from Bio-Alcamid. The last few years there have been many discrepancies with the major ingredients of the filler magically changing without notice to anyone. The foreign manufacturer hasn't been able to give a clear answer on the ratio of polyalkylamide (main ingredient) to water as they've gave several varying ratios over the last few years. There have also been confusion over who the true manufacturer is: first is was a Russian company, later Italian. They have stated the active ingredient (in writing mind you) is polyacrylamide and other times polyalkylamide. A company that can even be clear or honest about what's in their product can't be trusted. They do claim it is removable through puncture and pressing it out in a "worm" like string but I have yet to see this. Perhaps there is a good idea behind this concept but right now it's in the hands of a unscrupulous people. Ideally a reputable pharmaceutical company should scoop up this project, do the research on it's effectiveness and safety, and then bring it to the market.
“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.”
