ABSTRACT:
A method of mixing customized cosmetic products at a point of sale is disclosed. The method includes a suspension free of colorant to a container, adding one or more suspensions containing one or more colorants on top of the non-colorant containing suspension and adding one or more suspensions containing additional non-colorant ingredients on top of the one or more suspensions including the colorants, closing the container and mixing the suspension using a gyroscopic-type or rotary-type mixing apparatus. The container sidewall and bottom surface are coated with suspensions not containing colorant which prevents colorant materials from adhering to the sidewall and bottom portion of the container thereby providing for a more effective mixing of a customized cosmetic product at the point of purchase.
