I'm wondering how those of you who use Milk of Magnesia (MoM) to control oily skin apply it, exactly? I'd like to be able to apply it thinly enough to use liquid foundation over it--so I don't want the chalky-white appearance of a thicker application.

I've found that application using a cotton ball helps me to achieve a thin layer--but that a cotton ball soaks up most of the MoM, thereby wasting it; applying the liquid with my fingers tends to result in a thicker, obvious (chalky-looking) layer, which wouldn't work beneath foundation.*sigh*

Has anyone found a better tool and/or method for thinly applying MoM that can be hidden beneath makeup? (Heck, even if you don't use makeup but have found a way to achieve a thin layer of MoM without wasting it on a cotton ball, I'm all ears.)

Thank you,
PI
