A nozzle with an abrasion chamber for removal of the outermost layer of skin and the skin treatment system for use therewith. The abrasive material flows across a slot formed in the abrasion chamber. The path of the abrasive material may be generally helical. In the preferred helical embodiments, the paths are either vertically or horizontally oriented within the abrasion nozzle. To promote the spiral path of the material, some embodiments feed the abrasive material into the abrasion chamber at an angle causing the material to flow down the curved sidewall of a generally cylindrical abrasion chamber, thereby encouraging the spiral path. |
