Abstract:
A method for measuring the thickness of a cosmetic material-applied layer using skin curves comprises the following steps: a step of measuring curve data of a skin area which includes a first area without a cosmetic material-applied layer, and a second area with a cosmetic material-applied layer; a step of generating a 3D image of the skin area from the curve data; a step of determining a line profile area, which crosses the boundary line between the first area and the second area, in the 3D image; and a step of calculating the thickness of the cosmetic material-applied layer using a height difference according to the line profile area. By using the method for measuring the thickness of a cosmetic material-applied layer, the thickness of a cosmetic material-applied layer or a make-up-applied layer can be accurately and numerically assessed.
