A medical delivery device for dispensing a topical skin barrier composition to a targeted skin surface, the topical skin barrier composition consisting essentially of:

• a first component selected from the group consisting of butylated hydroxytoluene, benzalkonium chloride, methylparaben, ethylparaben, isopropylparaben, isobutylparaben, heptylparaben, benzyl paraben, butylparaben, chloromethylisothiazolinone, and methylisothiazolinone;
• a second component selected from the group consisting of monolaurin, Echinacea extract, cimetidine, dextran hydrogel, resveratrol, podophyllum, tea tree oil, thuj a oil, carrageenan, hydrated silica, and mixtures of two or more thereof;
• and
• a third component that is a combination of a hydrophobic carrier and an aqueous carrier;
• wherein the medical delivery device contains the topical skin barrier composition and is configured to dispense the topical skin barrier composition to form an anti-microbial barrier coating along the targeted skin surface so as to hinder transmission of wart-causing microbial entities to the targeted skin surface, and wherein said medical delivery device includes a pad, nozzle or roller.
