ABSTRACT:
A kit includes a first dispenser, a second dispenser and a colorimetric scale. The first dispenser stores and dispenses a first sun screening agent of a low sun protection factor of a first color. The second dispenser stores and dispenses a second sun screening agent of a high sun protection factor of a second color. The first sun screening agent and the second sun screening agent may be mixed together in order to obtain sun screening agent of intermediate sun protection factor and the first and second colors are blended. The colorimetric scale includes a plurality of representations of shades of blends of the first and second colors and a plurality of designations of sun protection factors. Each designation of sun protection factors has been calibrated to correlate with one of the representations of shades of the blended first and second colors in order to determine the sun protection factor of the intermediate sun screening agent.
