I am constantly searching for ways to reduce my beauty bill. One trick I have heard of and used to reduce oily skin is the application of Milk of Magnesia as a primer. All you need to do is dab this product on the oily areas of your face, let it dry and then apply your foundation (or BB cream). Milk of Magnesia helps keep your skin looking oil-free all day.
