When first applied, facial cosmetics create a soft, discontinuous distribution of pigment particles which provides a non-shiny color enhancement to the skin. As the day proceeds, the skin emits about 400 mg/cm² of sebum that overwhelms the 2 mg/cm² of cosmetic product applied on the skin. We have a small amount of cosmetic coating awash in a sea of sebum. This sebum is capable of wetting, plasticizing and solubilizing the cosmetic film, resulting in a shiny appearance, a change in color, and a loss in coverage. Consumers want their cosmetics to look the same at the end of the day as when they were initially applied.
