  • Device for the identification of acne, microcomedones, and bacteria on human skin
    Patent number: 5760407
    Abstract: The invention relates to a device and a method for the identification of fluorescing follicles that can be follicular impactions and/or microcomedones (clinically non-evident acne lesions), and/or comedones (clinically evident acne lesions) and/or bacteria on the face or other skin surface area. The inventive device allows the detection of both types of follicular fluorescence (yellow/green and orange/red). For safety reasons, to prevent skin burns and erythema, the filter on the ultraviolet light source removes substantially all the harmful UVB radiation (280-320 nm wavelength range). The filter used in conjunction with the detection means removes reflected and scattered light emanating from the subject's skin surface, thus increasing the sensitivity and discretion of the technique and making fluorescence detection easier and clearer.
