The skin scanner utilizes the Woods Light, also known as the black light.  A Wood’s Light allows substances that are not naturally luminous or phosphorescent to become florescent.  Valuable information is given by the different shades of florescence during examination. The florescence of the skin can vary greatly, with each part of the face. Healthy and normal skin appears light blue under the scanner.  Increased keratinization, dead cells, show as a white florescence.  The thicker the keratinized layers, the brighter the florescence.  Dark purple indicates thin and dehydrated skin cells.  Brown spots, otherwise known as age spots, become visible to the naked eye and orange/coral spots reveal seborrhea/comedones… bacteria and acne.
