Most collagen fillers are very short lasting as your body can break it down easily. Many of these are being phased out and the latest to fall was Evolence, a pig collagen. I was not one of the doctors who added this to my practice because I did not see an advantage over the hyaluronic acids and did not feel it would benefit my patients. Subsequently, this product has been pulled from the market. We are not aware of any real safety issues that may have prompted this at this time, but clearly this product did not perform to standards that met the needs of the patients and the doctors or it surely would have maintained its place in the filler world...stay tuned...One rule that is good to live by is don't be the first to use a device and don't be the last to stop using one!
Collagen is currently being phased out of the market as the new hyaluronic acid fillers are becoming more popular. Collagen injections to the lips typically last 4-6 months while the hyaluronic acid based fillers last twice as long. Collagen is sold thru Allergan. It comes in two variates Zyderm and Zyplast.
