An indicator for characterizing human skin condition includes a flowable
carrier, suitable for application to human skin, and at least one dye
soluble with oil found on human skin and visually changeable when in
solution with oil on human skin. A visual change in the at least one dye
is proportional to the amount of the oil present in solution, whereby
when the indicator is applied to an area of human skin, and the at least
one dye contacts and reacts with the oil in the area, the indicator will
display a visual indication of the skin condition in the area based on
the amount of the oil in the area.
