A treatment composition for treating human skin that has one or more particulate suspending agents in a concentration of from about 0.05% to about 2.0%, by weight, and one or more film forming polymers in a concentration of from about 0.1% to about 5.0%, by weight. Further, particles in a concentration of from about 1.0% to about 20.0%, by weight; one or more humectants in a concentration of from about 2.0% to about 20.0%, by weight; and, water are provided. The treatment compositions of this invention are used in an applicator having an applicator head having one or more applicator nozzles which may be in a array. The apparatus further has a reservoir containing the treatment composition, a sensor, and a CPU. The sensor takes an image of at least 10µm 2 of skin, the CPU analyzes the image to calculate one or more localized L values of individual pixels or group of pixels of the skin. Then the CPU compares the local L value to a predetermined background L value to identify skin deviations. A skin deviation occurs where the difference between the background L value and the local L value is greater than a predetermined ΔL S value. |
