The removable cartridge contains a sufficient amount of skin care active to make several doses of a personalized skin care composition. The single-use pod contains a sufficient amount of base ingredient to make a single dose of personalized care composition. To provide a personalized skin care composition, one or more personalization factors are inputted into the system. The hermetically-sealed, single-use pod is placed in the dispensing device such that it is in fluid communication with the replaceable cartridge containing the skin care active. The skin care active(s) is transported to the single-dose pod and mixed with the mixing element. However, the mixing element does not come into contact with the ingredients inside the single-use pod. The resulting personalized skin care composition can then be dispensed to a user.
