A method of depilation using a ruby red laser includes supplying optimum energy to a selected area of skin to cause follicular injury to the extent that depilation occurs without epidermal scaring.

Medical apparatus for performing treatment with a laser beam includes a laser oscillator generating a laser beam which is transmitted over an optical fiber to a hand piece including a plurality of rectangularly sectioned light guides, or kaleidoscopes, each having an incident end and an emission end. The kaleidoscopes are arranged in a side-by-side configuration in a hand piece. The emission end of the optical fiber is connected to an iron sleeve which is slidably mounted in the hand piece to pe...

A method for treating pigmentation abnormalities in human skin involves the use of a beam of laser radiation having an elongated cross-sectional area. The beam of pulsed laser radiation having an elongated cross-section is produced using a pulsed laser and a delivery system. An elongated area on the skin including a pigmentation abnormality is irradiated with the laser beam. The laser pulse parameters are tailored to the specific type of pigmentation abnormality (e.g., vascular lesions or tattoo...

A method of treating ice pick scars is provided in which the epidermal layer surrounding an ice pick scar is ablated to provide a recipient hole into which skin is grafted. Smoothing of the skin after grafting may then be performed with permanent rejuvenation.

A method of facial rejuvenation is provided in which ablation of an area of skin is accomplished to above the papillary dermis, providing effective permanent smoothness.

According to the invention, a method is provided for disrupting the targeted lesion in skin, such as is necessary in treatment of vascular or pigmented lesions. A microplasma is generated in a target region of skin, the microplasma disrupting the skin ("plasma ablation") to enable removal of the targeted lesion. The microplasma absorbs radiation energy and expands, creating high pressure in the surrounding region which causes disruption of the targeted lesion in that region. A beam of pulsed las...

A method and apparatus for simultaneously removing multiple hair follicles from a skin region of a patient. The method includes the step of illuminating the hair follicles with a large-area, optical radiation field by way of a transparent contact device proximal to the skin region. This allows portions of the hair follicles to be heated and then removed, while the surrounding skin region is left relatively free of injury.

A laser treatment method for removing unwanted human hair includes irradiating a treatment site with post-coherent light of selected wavelength and peak power level and post duration, and repeating the post-coherent laser irradiation on one or more subsequent occasions with selected light parameters. A therapeutic treatment device has a laser and associated support elements and has a dermatology handpiece with a distance gage, a conduit for applying pressure and/or cooling to the treatment site ...

A photoacoustic probe for port wine stain (PWS), burn and melanin depth measurements is comprised of optical fibers for laser light delivery and a piezoelectric element for acoustic detection. The probe induced and measured photoacoustic waves in acryl amide tissue phantoms and PWS skin in vivo. Acoustic waves were denoised using spline wavelet transforms, then deconvolved with the impulse response of the probe to yield initial subsurface pressure distributions in phantoms and skin. The waves we...

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...
