I would have considerable reservation about using collagen for breast augmentation. In its usual clinical application only one or two cc's is injected in the face for augmentation of certain areas and wrinkle lines. In order to have a satisfactory enlargement of a breast it would require many

cc's of collagen. Moreover it is well known that collagen is extremely temporary. Not only does it not last for a lifetime; collagen in the face often lasts no more than three months. I would be reluctant to predict some of the side effects that may occur if such large volumes of collagen were used. I suppose, theoretically, it could trigger some sort of severe immune response. In summary, I wouldn't even consider it.
