Skin color measurement of face regions.

Locations of skin color measurements. Measurements were made from the left cheek, right cheek and forehead using a Konica Minolta CM2600d spectrophotometer. Measurements were made in the CIELab color space, in duplicate. Mean values across both measurements and all 3 locations were calculated for luminance (L*), redness (a*) and yellowness (b*) color axes. The individual in the image has given written informed consent (as outlined in the PLoS consent form) to publish her image.
