Bovine Collagen Fillers
Bovine collagen is processed from the skin of cows. Approved in the 1980s as a wrinkle treatment, bovine collagen is still in wide use as a cosmetic filler.
Bovine collagen is effective, and less expensive than other treatments. It can cause allergic reactions, so allergy skin testing is generally done before beginning the injections.
Collagen injections are broken down naturally by the body. Injections need to be repeated two to four times per year to maintain results.
Collagen is a natural protein that supports the skin. Injectable collagen formulas derived from human dermis include Cosmoderm® or Cosmoplast®. Zyderm® and Zyplast® are forms of bovine collagen that, unlike human derived collagen, require prior allergy testing. The results may last 2 to 4 months.
