Laser systems and methods called UV Dermablators allow clean and precise skin removal while minimizing damage to the skin underneath the treatment area. The depth of incision can be controlled through the physiological function of the skin, ie feedback due to the inflow of blood from the incision area when the skin is incision enough to cause bleeding. A second laser, such as a UV light source with different wavelengths, heats the blood sufficiently to solidify and soak. Other characteristics allow for precise control, and the epithelium is removed down to the dermis along the ups and downs of the dermis. This aspect and depth control is achieved by careful observation with adequate spatial resolution to separate the relief of the dermis projections, which is supported by spectroscopic detection, confirming when the epidermis is removed to expose the underlying dermis. Other properties are used to control the depth of incision at each location, providing a feedback control mechanism that utilizes optical properties such as color, appearance, and reflection of a defined skin layer. |
