Manufactured by Inamed Aesthetics, and approved by the Food and Drug Administration in 2004, Hylaform/Hylaform Plus is a hyaluronic acid based dermal filler, used for moderate to severe lines and wrinkles produced by aging, and collagen degradation. It is also used in medicine, to treat, and help to manage osteoarthritis. It is a clear, injectable gel produced from specially bred rooster combs, and tends to last longer than other dermal fillers.
The hyaluronic acid used in Hylaform/Hylaform Plus, is harvested from the connective tissues in the fleshy portion of the top of the rooster’s head, called rooster comb. The roosters are specially bred for the purpose of making Hylaform products, and the rooster tissue is then purified, sterilized, and then stabilized chemically, into a clear gel form. It is minimally modified, so no skin test is required, but you should not use Hylaform if you are allergic to eggs or feathers.
Hypersensitivity is rare, but it could occur to individuals with bird allergies, however, there is absolutely no risk of contracting bird flu from Hylaform. When Hylaform is modified with the rooster comb hyaluronic acid, it is purified, then sterilized at a temperature which is higher than necessary to kill the bird flu virus. Both Hylaform, and Hylaform Plus last longer than bovine (cow) dermal fillers, and do not require pre-testing, for skin allergies.
