ABSTRACT:
Disclosed are topical compositions which provide good coverage of skin imperfections, e.g., pores and uneven skin tone, while retaining a natural skin appearance. The compositions contain a charged particulate material dispersed throughout a thickened, hydrophilic carrier. The charged particulate material allows the compositions to have a Coverage Efficiency Ratio of greater than about 20.
