Abstract
A system to record the color, size and location of skin blemishes on the skin using an objective standard is provided. The system includes a color scale containing colors and shades of colors sufficient to portray a skin blemish; a blemish-size gauge for measuring the size of the blemish; a distance scale for measuring the distance of the blemish from reference points; and a body map of the skin surface of the entire human body with reference points for recording the location of the blemish. Each color in the color scale and size in the size gauge is given an individual designation for easy reference. The color scale and the measuring devices may be combined in one multi-functional tool and with a folded chart for easy storage in a folder to protect the colors from changes due to exposure to light.
