ABSTRACT:
A laser system (called a UV Dermablator) and method that enables a clean, precise removal of skin while minimizing collateral damage to the skin underlying the treated region. The depth of ablation can be controlled via feedback from the physiology of the skin, namely the infusion of blood into the area of excision when skin has been ablated to a sufficient depth to produce bleeding. A second laser, such as a uv light source with a different wavelength, to penetrate the blood, heating it sufficiently to coagulate the blood. Other features provide precise control, permitting the epidermis to be removed down to the papillary dermis, following the undulations of the papillary dermis. This lateral and depth control may be accomplished by using careful observation, assisted by spectroscopic detection, to identify when the epidermis has been removed, exposing the underlying dermis, with spatial resolution appropriate for the spacing of the undulations of the papillary dermis. Yet other features which provide a feedback control mechanism which utilizes the optical characteristics such as the color, appearance and remittance of the definable skin layers to control the depth of ablation at each location.
