Topical compositions containing an isolated bioactive polyelectrolyte (BP) fraction and an active agent, and uses of the composition to improve a skin condition are described. In particular, a topical composition comprising a cosmetically or pharmaceutically acceptable carrier, at least one active agent, and an effective amount of an isolated bioactive polyelectrolyte (BP) fraction comprising an isolated fulvic acid fraction, an isolated humic acid fraction, or an isolated mixture of fulvic acid and humic acid fraction is provided. The isolated fulvic acid fraction consists essentially of ionic nanocrystalline fulvic acid molecules, and the isolated humic acid fraction consists essentially of colloidal humic acid particles having an average particle size of about 1 to 10 microns in diameter. |
