Abstract
An instrument and technique for the removal of dermal layers in a controlled manner utilizing (i) a high-pressure gas delivery source, (ii) a source for delivery of a cooling fluid and a crystalline abrasive; and (iii) an aspiration source. The systems together cooperate to jet high-velocity gases and cooling fluids, together with abrasives crystals, against a patient's epidermis to abrade away surface layers in a skin resurfacing treatment. The method of the invention provides a periodic removal of superficial skin layers which enhances the synthesis of dermal collagen aggregates by inducing the body's natural wound healing response. The method of the invention creates more normal dermal architectures in skin with limited depths of skin removal by the series of superficial treatments that may be comparable to the extent of collagen synthesis caused by a deeper skin removal treatments such as CO.sub.2 laser skin removal.
