An aqueous isotropic liquid cleansing and moisturizing composition is provided having a surfactant; a thickening agent, and a solid particulate optical modifier that modifies the appearance of the skin after wash off. Exemplary coatings include aluminum oxide in an aqueous suspension, with aluminum oxide particles contained in the suspension having size typically between 0. The method eliminates redundant modules in the collection by redefining execution interdependencies among the modules. If a potential worm attack may have occurred, intermediate action, such as throttling of traffic, may occur.
