Q. You recently had an article about treating seborrheic dermatitis with milk of magnesia. My mom is wondering how much milk of magnesia she should take.
A. Please tell your mother NOT to swallow milk of magnesia (MoM) for her skin problem. This is a powerful laxative and if she consumes too much, she will be dashing for the bathroom.
Instead, suggest that she apply MoM to the itchy, flaky, red areas of her skin. For reasons that are not clear to us, this remedy seems to help both acne and seborrheic dermatitis.
