Milk of Magnesia is often used as a facial primer because it has de-greasing properties and makes the skin matte. As a basic solution (10.5 pH), Milk of Magnesia can also be used as an anti-bacterial, anti-fungal, or anti-viral (or so I've read). But can the Herpes Simplex Virus be spread from person to person through the use of Milk of Magnesia, as in, one person applies it to her face and then another person, sharing the solution, applying it to her face shorty afterward?
