The term 'Roll-On Alternative' refers to two different solutions for applying a product to the skin. The first solution is an AEROSOL, which is a pressurized container that dispenses a product in the form of a fine SPRAY. The second solution is a SPRAY, which is a device that releases a liquid or powder in a fine mist. Both solutions are alternatives to the traditional roll-on applicator, which applies a product in a thin layer by rolling a ball over the skin.
