1. A method of treating a skin surface of a subject, comprising:

  • positioning a handheld device against a skin surface of the subject, the handheld device comprising;

    a body comprising a housing;

    a working end portion positioned along a first end of the body, the working end portion comprising a distal end configured to contact the skin surface, wherein the working end portion comprises a perimeter along the distal end;

    a first aperture arrangement comprising at least one first port located along or near the working end portion, the at least one first port being in fluid communication with a vacuum source via at least one passageway; and

    a second aperture arrangement comprising at least one second port located along or near the working end portion, the at least one second port being in fluid communication with a treatment media source;

    activating the vacuum source to simultaneously deliver a treatment media to the skin surface through the at least second port, wherein the treatment media comprises a liquid, and to aspirate spent treatment media through the at least one first port and the at least one passageway, thereby selectively providing a volume of the treatment media to the skin surface of the subject;

    wherein activating the vacuum source facilitates delivery of treatment media to subsurface skin tissue of the subject and causes adjacent skin surface to at least partially puff up to facilitate the treatment method.
