Abstract
An abrasion device and method for delivery of substances into the skin using a microabrader for delivering a substance into the skin are disclosed. An abrasion device with a cover is also disclosed. Such devices and methods can be effectively used to deliver bioactive substances into skin.
Claims20
A method for delivering a substance into skin comprising the steps of:
- applying printed indicia onto the skin which corresponds to a predetermined abrasion area,
- providing an abrader having an abrading surface with an abrading surface area said abrader surface area having a plurality of microprotrusions;
- moving the abrader across said skin to produce an abraded area within the bounds of said pre-determined abrasion area thereby producing abrasions in the skin within said predetermined abrasion area, and;
- applying said substance to the abraded area.
1 more element
A system for delivering a substance into skin comprising:
- a skin marker, for marking printed indicia directly onto the skin;
- a skin template, which is applied to the skin and has an opening corresponding to a predetermined abrasion area, wherein the skin template is used as a guide for the skin marker to form the indicia which correspond to the predetermined abrasion area, and
- an abrader having an abrasion surface containing a plurality of frustoconical or frustopyramidal microprotrusions further comprising at least one scraping edge projecting from said abrading surface adapted for movement across said skin to produce an abraded area on the skin within the bounds of said predetermined abrasion area.
