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.

Claims

1. A method of treating a patient'"'"'s skin, comprising:

determining a pigmentation level of the skin by measuring radiation reflected from the skin in response to illumination thereof, and

selecting a treatment for application to the skin based on said determined level of skin pigmentation.

2. The method of claim 1, wherein the step of determining the pigmentation level comprises utilizing an optical sensor to detect said reflected radiation.

3. The method of claim 2, further comprising selecting said optical sensor to be any of a CCD or a CMOS detector.

4. The method of claim 3, further comprising utilizing said optical sensor to image the skin surface.

5. A method of treating a patient'"'"'s skin, comprising:

detecting radiation reflected from the skin in response to illumination thereof,

determining the skin type based on said detected reflected radiation, and

varying a treatment applied to the skin based on said determined skin type.

6. The method of claim 5, further comprising utilizing an optical sensor to detect the radiation reflected from the skin.

7. The method of claim 6, further comprising selecting said optical sensor to be any of a CCD or a CMOS detector.

8. A method of determining a subject'"'"'s skin type, comprising

illuminating at least a portion of the skin with radiation,

detecting at least a portion of the illuminating radiation that is reflected from said skin portion,

determining the skin type based on said detected reflected radiation.

9. The method of claim 8, further comprising generating an image of said illuminated skin portion by utilizing said detected radiation.

10. The method of claim 8, further comprising utilizing an optical sensor to detect said reflected radiation.

11. The method of claim 10, further comprising selecting said optical sensor to be any of a CCD or a CMOS detector.

12. The method of claim 10, further comprising selecting a treatment for application to the subject'"'"'s skin based on said determined skin type.
