An instrument and technique for the removal of epidermal layers in a
controlled manner utilizing a hand-held instrument with a working end
that (i) a vacuum aspiration system, (ii) a source for delivery of a
sterile fluids or pharmacological agents to the skin; and (iii) a skin
interface surface in the working end that has specially shape structure
for abrading surface layers of the patient's epidermis as the working end
is moved over the patient's skin while at the same time causing rapid
penetration of the fluids into the skin for therapeutic purposes.
Movement of the working end across the skin causes abrasion of the
surface layers in a path over the patient's skin. The method of the
invention may be used in a periodic treatment for the removal of
superficial skin layers that 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 neocollagenesis caused
by a deep skin removal treatment (e.g., CO.sup.2 laser skin removal).
