Nicholas Maggio, plastic surgeon helped make Daniel "visible" again, by creating a realistic face mask made from a Derma-plex compound, which had the same feel and texture as realistic skin tissue. Nick refined every detail, with special contact lenses for the eyes, a hair piece, caps for the teeth, eyelashes. etc. He also used the same technique for the hands, by making a pair of "gloves" with the same compound.
