Abstract
A system for atraumatic removal of skin surface layers in a treatment to induce neocollagenesis in the dermis to reduce wrinkles and alter the architecture of the dermal layers. A preferred embodiment of the inventive system comprises (i) a hand-held instrument with a resilient floating skin interface that carries microscopic diamond fragments for abrading the skin surface in a controlled manner, (ii) a fluid source for supplying sterile fluids to the skin interface for cleaning skin debris from the skin interface; and (iii) a negative pressure source for pulling fluid to the skin interface and thereafter aspirating fluid and skin debris from a treatment site. The skin interface is formed of a resilient floating member (e.g., silicone) that allows the working surface to flex and atraumatically engage the topography of the skin surface as it is translated across a treatment site. The system allows substantially deep surface layer removal without significant pain.
