I have had some success using milk of magnesia to stop oil and keep skin matte, the main problem I am having is removing the MoM after it has dried. If i use water my face will get shiny and if I scrub it off too much my skin will turn red. I have ordered pure magnesium hydroxide powder and DeodoMom Jar Deodorant which contains magnesium hydroxide in a creme form. I will post my results as soon as they both get here and are tested.
