The devices are designed such that the microstructures are able to grip the skin or tissue surrounding a wound, optionally closing the wound, or securing the tissue or skin in place. Also provided are wound closure systems that comprise one or more micro structure wound closure devices along with other components, such as protective covers and wound healing therapeutics. A variety of pack­ aging specifications are disclosed, as is a dispenser apparatus configured to enable simple one-handed application of the wound clos - ure devices. Methods described herein provide for the closure of various wounds with the wound closure devices and systems.
