collagen sheets obtained from human organ donors. It consists of the deepest layers of skin and contains no living cells. Therefore, it is not subject to transplant rejection or common infections. It is processed according to U.S. Food and Drug Administration and American Association of Tissue Banks regulations. Placing this collagen under the skin replenishes the missing deeper layers of skin thereby elevating depressed scars or skin wrinkles. It can also be placed in the lips to make them appear larger. The material can last more than 2 years without any visible loss of the collagen but there is no guarantee as to how long the correction due to insertion of this collagen will last. The edges of the sheet can felt but not usually seen for 4 to 6 weeks. After that there is ingrowth into the material & the edges cannot be felt or seen. Dr. Stone currently uses Alloderm for lip enlargement/augmentation, nasolabial fold treatment frown line treatment & in revision breast surgery for implant support or salvage.
