Abstract

The make-up unit (1) comprises a container (3) for the fluid product (M) and a cap (2) bearing a stick (4) provided with an application organ (5) which plunges into the fluid product (M) when the unit (1) is in closed position. The container (3) contains a retention member (10) which is in contact with the fluid product (M) and contains a cosmetically acceptable dissolvent capable of fluidifying said fluid product (M). The retention member (10) releases the cosmetically acceptable dissolvent during the storage in order to re-fluidity the product (M) as it dries.

Claims
