Abstract
The present invention relates to a method of hair depilation comprising the steps of providing an augmentation compound that readily absorbs a selected wavelength of laser light energy, encapsulating the augmentation compound within a liposimal carrier, applying an effective amount of the encapsulated augmentation compound to a region of tissue to be depilated sufficient to cause the compound to accumulate within the dermis surrounding each hair follicle and respective papilla, providing a laser light applicator capable of producing a wavelength of energy matched to the selected wavelength of absorption for the augmentation compound, positioning the laser light applicator above the region of skin treated with the augmentation compound and, applying a pulse of laser energy of the selected wavelength to the region of skin treated with the augmentation compound, the pulse of laser energy having a radiant exposure dose of sufficient energy and duration to cause damage to the hair follicle and papilla so that hair regrowth is prevented and surrounding tissue remains undamaged.
