  • Publication number: 20090118698
    Abstract: The invention relates to a device and a process for introducing an active ingredient into the skin. The device comprises a roller that is mounted to rotate around the longitudinal axis thereof and on whose outside peripheral surface a number of needles project radially outward. After the active ingredient has been applied on the skin, the roller rolls over the skin. In this case, the needles penetrate the skin and open up fine channels there, through which the active ingredient penetrates through the epidermis up to the dermis.

  • Publication number: 20070088264
    Abstract: A device for introducing an active ingredient into the skin. The device has at least two rollers mounted so that they are rotatable around their longitudinal axis, from whose outer peripheral surface multiple needles project radially outward. In order to make application of the device over a large area easier, the rollers are situated parallel to one another and laterally offset relative are situated parallel to one another with axially neighboring rollers being laterally offset relative to one another such that a projection of one of the rollers perpendicular to the longitudinal axis thereof comes to rest on an extension of the longitudinal axis of the neighboring parallelly situated roller without needle-bearing areas of the outer peripheral surfaces of both rollers overlapping in an axial direction.
