Abstract
A method and apparatus are provided for targeting lipid-rich tissue to effect a desired, the method/apparatus involving irradiating the lipid-rich tissue with energy at a wavelength preferentially absorbed by lipid cells, such wavelength being preferably in a band between 880 nm and 935 nm, 1150 nm and 1230 nm, 1690 nm to 1780 nm, or 2250 nm to 2450 nm with a fluence and duration sufficient to achieve a desired treatment. For preferred embodiments, the irradiation wavelength is between 900-930 nm, 1190-1220 nm, 1700-1730 nm, or 2280-2350 nm. The method and apparatus may for example be used to target one or more sebaceous glands for the treatment of acne or hair removal, to target subcutaneous fat for removal thereof or for targeting fat on anatomical elements for various purposes.
