Abstract: The present invention relates to compositions with enhanced UV screening properties and methods of making same, and specifically, UV screening compositions including UV filters and silica boosters. The compositions consist of any suitable cosmetically acceptable carrier, one or more organic or inorganic UV filters and spherical silica. The present invention also discloses methods of making UV-screening compositions including spherical silica, wherein the methods comprise adding spherical silica during the process of combining the cosmetically acceptable carrier and UV filters or after the cosmetically acceptable carrier and UV filters have been combined.
