Collagen

Collagen is the primary building block that holds our tissues together. It is also the name of the original filler material. It came in three forms: Zyderm I, Zyderm II, and Zyplast. For a very long time, this was the only viable filler on the market. The effects of Zyderms were very short lived. The Zyplast seemed to last only a couple of months. Essentially only the wealthy could afford this service. These products have now been replaced with Restylane®, Perlane®, and to a lesser extent, Jevederm®. The Zyplast was fantastic for treating the edge of the lips, but the longevity of the product limited its usefulness.
