Summary:A method for demonstrating pre-emergent pimples is disclosed. The method includes providing a camera having a 25 mm macro lens and a linear polarizing filter including from 10 to 50 narrow band filters in the spectral range of 400-970 nm, and a light source having a linear polarizer oriented vertical to a polarization plane of the camera polarizer; taking a sequence of images of the face of a subject with the camera; creating an erythema map of the imaged area using oxy-hemoglobin values at each corresponding pixel; taking a visible-light image of the face of the subject; and comparing the images to see pre-emergent pimples. The method enables consumers to see pre-emergent pimples and treat them, which results in preventing the pimples from emerging or reducing the emergence of the pimples.
