Embodiment Construction
[0068] figure 1 is a schematic illustration of some basic elements of a photocosmetic device according to aspects of the present invention. Area 110 is an area of the patient's skin to be subjected to the selected photocosmetic treatment. The skin area 110 has a base layer 140 between the epidermis 120 and the dermis 130 . Typically, photocosmetic treatments involve treating target areas located within the epidermis 120 or dermis 130 . For example, in the case of hair removal, the bulb 150 of the hair follicle 160 may need to be heated. Additionally, it is possible to heat only a portion of the bulb 150, such as the basement membrane 152 between the mastoid and the capsule.
[0069] In some embodiments of the present invention, the main subsystem of the device 100 includes a handpiece 170 , a base unit 120 and a cord 126 for coupling the handpiece 170 to the base unit 120 . The base unit 120 may include a power supply 124 for powering control electronics 122 and a source...

Abstract
Photocosmetic device (100) for use in medical or non-medical environments (e.g., a home, barbershop, or spa), which can be used for a variety of tissue treatments. Radiation is delivered to the tissues via optical systems (520 for example) designed to pattern the radiation and project the radiation to a particular depth. The device has a variety of cooling systems including phase change cooling solids and liquids to cool treated skin and the radiation sources (510 for example). Contact sensors (1712) and motion sensor (1820) may be used to enhance treatment. The device may be modular to facilitate manufacture and replacement of parts.
