Abstract
Photocosmetic device 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 tissue via optical systems 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. Contact sensors and motion sensor may be used to enhance treatment. The device may be modular to facilitate manufacture and replacement of parts.
