Microabrader with controlled abrasion features

An abrader device for delivering a substance into skin via an abrasion process, said abrader device comprising:

• a housing adapted to be pressed against the skin at a desired delivery site, said housing having a top with an upper opening and a bottom defining a lower opening, which surrounds the delivery site;
• an applicator head disposed in the upper opening and movable across the lower opening to abrade the delivery site;
• and
• an abrader surface attached to said applicator head whereby said housing remains firm and stationary at the delivery site and structure of said housing and said applicator head controls parameters of the abrasion process.

An automatic abrader device for delivering a substance into skin via an abrasion process, said abrader device comprising:

• a housing adapted to be fixedly attached to the skin at a desired delivery site, said housing having a top with an upper opening and a bottom with a lower opening;
• a push button arranged to project through the upper opening of the housing;
• a spring mechanism surrounding the push button;
• a series of one or more levers or perpendicularly arranged horizontal bars in operable communication with said push button;
• and
• an abrader surface movable across the lower opening of the housing to abrade the delivery site and in operable communication with said push button and said series of one or more levers or perpendicularly arranged horizontal bars wherein when the push button is pressed or activated said abrader surface moves into contact with the skin at the delivery site and moves across the delivery site in one direction in conjunction with the movement of said series of one of levers or perpendicularly arranged horizontal bars.
