Abstract
Systems and methods are disclosed for cosmetic augmentation by forming a biocompatible cross-linked polymer having a multi-phase mixture with a time release catalyst; injecting the mixture into a patient as a viscous fluid; after injection, activating the catalyst to cross-link the polymer after a predetermined period after injection into a patient; and augmenting soft tissue with the biocompatible cross-linked polymer.
