A Prospective Study Evaluating the Treatment of Forehead and/or Glabellar Lines With the Cryo-Touch IV Device

myoscience Inc. (Redwood City, CA) has developed a device for a novel, minimally invasive facial rejuvenation procedure designed to soften hyperdynamic facial lines. The myoscience Cryo-Touch IV device uses well-established principles of cryobiology to cause localized reduction in muscle activity resulting in a reversible reduction in facial animation and the appearance of facial lines. The device operates on well-established cryobiology principles; that localized exposure to controlled low temperature conditions can alter tissue function. The therapy treats targeted motor nerves with low temperatures via a cold probe in the form of an assembly of small diameter needles, creating a highly localized treatment zone around the probe. The thermal algorithm is designed to produce a reversible loss of nerve conduction resulting in a temporary decrease in muscle contractility. Prior studies of Cryo-Touch, Cryo-Touch II and Cryo-Touch III have provided strong evidence of effectiveness and safety for applications in this indication. The goal of the study described herein is to show the safety and effectiveness of this approach using the Cryo-Touch IV device.
