CyberSkin is the brand-name of a soft elastomer material that is intended to emulate the feel of human skin. It is made by the adult toy manufacturer Topco Sales. The company states that the technology behind CyberSkin is a "new Aerospace 601 computerized injection molding machine, originally designed by NASA engineers..."
Similar materials are available under other brand names, such as Ultraskin, Eroskin, Softskin, SoftTouch, Cyber Jel-lee, New supersoft, Futurotic and UR3 (Ultra realistic 3.0). All are soft and stretchy, with a velvety texture that is caused by talcs and cornstarches used to prevent the material from becoming unpleasantly sticky.
The materials, from the group of thermoplastic elastomers, are mixtures of polyvinyl chloride and silicone. As such, they are attacked by oil, petroleum, and silicone oils, therefore only water-based lubricants can be used without causing damage.
