Abstract: Handheld skin cleansing devices (100) including a pump (17), a treatment container (46), a waste container (47), and first and second conduits (23,24) for delivering and withdrawing fluid to and from a tip (1) of the device. Some of the handheld skin cleansing devices (100) include one or more pump protection systems (200), a fixed waste container (47) with a removable bottom cap (50), and/or a light source (90) configured to emit light on the user's skin proximate the tip (1) and selectively controllable via an interface (13) on the main body of the device. A tip (1) for a handheld skin cleansing device (100) including an outer surface having first and second openings (1A, 1B) through which treatment fluid is delivered to and withdrawn from the outer surface and a light source (90) configured to emit light towards a user's skin proximate the outer surface, wherein operation of the light source (90) is selectively controllable via an interface (13) on the main body portion.
