Handheld skin cleansing device

A handheld skin cleansing device comprising:

• a first conduit providing fluid communication between a treatment container and a first opening in a tip of the device;
• a second conduit providing fluid communication between a second opening in the tip and a waste container of the device;
• a pump housed within the handheld body and in fluid communication with the waste container, the pump configured to form a pressure differential between the waste container and the second opening in the tip so as to direct fluid from the treatment container, to the tip, and into the waste container via the first and second conduits when the tip is applied to skin of a user;
• and
• a pump protection system configured to turn the pump off upon detecting at least one of the following:
• (i) that fluid in the waste container reaches a predetermined level or (ii) that fluid in the treatment container reaches a predetermined level corresponding with having dispensed enough fluid for the fluid to reach a predetermined level within the waste container, the pump protection system comprising a sensor having three or more conductive pins extending an equal distance into the waste container or the treatment container, respectively, and arranged about a perimeter of an interior of the waste container or the treatment container, respectively, the pins being configured to detect when fluid in the waste container or the treatment container, respectively, contacts at least two of the pins simultaneously.

• a second conduit providing fluid communication between a second opening in the tip and a waste container of the device;
• a pump housed within the handheld body and in fluid communication with the waste container, the pump configured to form a pressure differential between the waste container and the second opening in the tip so as to direct fluid from the treatment container, to the tip, and into the waste container via the first and second conduits when the tip is applied to skin of a user;
• and
• a trap having a tortuous conduit extending between a first opening and a second opening, the first opening being in fluid communication with an interior of the treatment container and the second opening being in fluid communication with an area outside of the treatment container.

A handheld skin cleansing device comprising:

• a tip comprising:
• an outer surface;
• a first opening through which a treatment fluid is delivered to the outer surface;
• a second opening through which the treatment fluid is withdrawn from the outer surface;
• and
• a body portion having a distal end on which the tip is situated or integrally formed, the body portion comprising:
• a pump configured to deliver and withdraw the treatment fluid to and from the outer surface, respectively, and
• a light source at a distal end of the body portion, the light source configured to emit light towards a user's skin proximate the outer surface,
• wherein operation of the light source is selectively controllable via an interface on the main body portion.
