the first light-emitting diode emits light in a first wavelength spectrum, and
the second light-emitting diode emits light in a second wavelength spectrum, which is different from the first wavelength spectrum;
a first measurement, measured using the scanning device from a first location of a customer's skin;
a second measurement, measured using the scanning device from a second location of a customer's skin that which is different from the first location, wherein the first and second locations are free of irregular pigmentation; and
