Apparatus and methods for providing fractional treatment of tissue (eg, skin) using a laser. In this method, one or more microscopic treatment zones of necrotic tissue and thermally altered tissue are created, leaving intentionally growing tissue surrounding the microscopic treatment zone. The apparatus includes one or more light sources and an emission system for generating a microscopic treatment zone in a predetermined pattern. The microscopic treatment zone is limited to, for example, the epidermis and the dermis, or spans the epidermal dermal transition, and the stratum corneum above the microscopic treatment zone may not be used. |
