Abstract: Various packaged probiotic compositions, methods of producing a packaged probiotic composition, and cosmetic methods are described. A packaged probiotic composition includes a storage vessel that defines a first chamber, a second chamber, and a wall that separates the first and second chambers. The first chamber includes a lyophilized probiotic bacteria matrix and the second chamber includes a moisture-providing composition. A dispensing mechanism is individually coupled to the first and second chambers and, when activated, draws pre-measured portions of the lyophilized probiotic bacteria matrix and the moisture-providing composition from the respective first and second chambers, mixes the pre-measured portions, and dispenses the resulting mixed composition.
