I recently had a friend ask me under the video, what exactly is a bioband? Does it stay in the body forever like a prosthesis, or does it slowly absorb after treatment? For bioband, the name of its material is allogeneic decellularized dermis, or allogeneic decellularized dermis scaffold, which is not immunogenic in itself and is mainly implanted into the body as a collagen scaffold, over which skin implants can be placed, or tissue spacing can be performed. The bioband can be made into strips and then tightened for the female private part to achieve a urethral lift. After implantation, it will be partially absorbed, but not completely, and the degree of absorption varies from person to person. If there is no rejection or inflammatory reaction after implantation, it is usually permanent. It grows completely with the surrounding tissues and maintains a good tightening effect on the private parts, and the satisfaction level after the surgery is usually high. Bioband is a more specific form of material that is mainly used for covers such as narrowing of the female private parts. After implantation, some of it will be absorbed by the body, but not completely.
