Abstract: A roller applicator device and method for distributing preparations on a user's skin and, in particular, hard to reach body parts. The applicator comprises a roller portion for containing and distributing a preparation, a detachable and extendable handle portion, and a resealable storage container. In order to use the applicator, the extendable handle portion is attached to the roller portion. The roller portion comprises a sealed canister containing a preparation and having a porous layer on the exterior of the canister for distributing the preparation to the user's skin. The canister has apertures through which the preparation is discharged due to centrifugal forces incurred by rolling the applicator over the user's body. There is a locking device that when engaged, prohibits the roller from rotating and may be used to rub preparation into the user's skin.
