A cosmetic container that enables a user to easily mix a first product and a second product, that are stored separately within the cosmetic container, with a simple twist of the dialer before the first use. The first product is in a first product container, while the second is in a second product container. The cosmetic container includes the first product container, the second product container, a pump dispenser, an outer cap, a seal cap, a piston, an elevator, and the dialer.
