    摘要： A self-contained, handheld probe for measuring at least one parameter of skin condition, has one or more light sources that may be used to project light upon the skin. The light projected is of a selected wavelength known to generate a specific fluorescence that is indicative of the skin parameter of interest in accordance with a known correlation. To produce the proper excitation light, a light source generating that wavelength is used or a broader spectrum of light is selectively filtered to pass the wavelength of interest. Lenses, fiber optic elements or waveguides may be employed to project the light onto the skin at a specific location and/or to deliver the skin response to a light detector, which measures the light signal from the skin. and generates an output signal indicative of the value of the at least one parameter. The probe may be used to measure skin age, photodamage and/or proliferation.

    摘要： The present invention is directed to methods for treating acne. The methods include exposing the subject afflicted with acne to ultraviolet light having a wavelength between about 320 to about 350 nm, such that the acne is treated, e.g., inhibited, diminished, eradicated or prevented. In a preferred embodiment, the wavelength is 335 nm and is emitted by either a nitrogen laser or a third harmonic of a NdYAG laser. Treatments can be administered over a several week period, where the subject is exposed to sequential doses of ultraviolet light to obtain beneficial effects, e.g., a reduction or elimination of the acne, e.g., an eradication or diminishment of the bacteria responsible for acne, e.g., Propionibacterium acnes.

    摘要： Light reflected from skin has two components: regular reflectance, or "glare" arising from the surface, and light backscattered from within the tissue. The regular reflectance contains the visual cues related to surface texture, whereas the backscattered component contains the cues related to pigmentation, erythema, infiltrates, vessels and other intracutaneous structures. Unlike the backscattered component, regular reflectance preserves the plane of polarization of polarized incident light. Thus, viewing skin through a linear polarizer, under linearly polarized illumination, separates the two components of tissue reflectance. When the planes of polarization are parallel, images with enhanced surface detail are obtained. When the planes are orthogonal, wrinkles and surface detail disappear, and an enhanced view of vasculature and pigmented lesions is obtained. Apparatus for performing such inspection is disclosed.
