Milk of Magnesia, or Magnesium Hydroxide, is a milky white saline laxative containing Magnesium. It is affectionately referred to by acne sufferers as MoM, and sold under the brand name ‘Phillips Milk of Magnesia – named after its founder, Charles Henry Phillip in 1880 (Today the rights are owned by Bayer).

Milk of Magnesia for Acne Treatment

MoM first gained popular use as a potential ‘household’ acne treatment in the early 20th century. Because of its alkaline properties, it tends to cause shrinkage of skin pores and a reduction of sebum production. Less sebum would theoretically result in a reduction of acne lesions, and its ‘pore shrinking’ properties make it a popular ‘base’ or ‘primer’ for makeup. MoM is reported by some people for its effectiveness as an acne spot treatment and an antibacterial.

When treating acne, the ‘plain’ Milk of Magnesia is usually recommended to avoid problems with mineral oil or other additives. This can be found in most common drug or grocery stores in the pharmaceutical section.

Controversy Surrounding Milk of Magnesia for Acne Treatment

Although numerous people have reported positive results from its use, there are potential problems with Milk of Magnesia for treating acne. These stem from the fact that Milk of Magnesia is an alkaline by nature, and the PH balance of our skin is more acidic. The very nature of how MoM works therefore is by disrupting the skin’s PH balance – often for many hours. This can lead to excessive drying and a reduction in the skin’s natural bacterial defense. Another potential complication is with MoM’s use as an astringent – by shrinking pores it could theoretically exasperate the conditions which lead to acne – clogged pours. This in combination with increased bacterial activity would eventually lead to more acne.

The long term consequences of Milk of Magnesia as an acne treatment are therefore questionable. No doubt it can control oil, but does it actually encourage conditions favorable to acne? While long term reports of its use are unavailable – the scientific evidence suggests against it. One of the many other natural choices which have proven effective, such as vinegar, may be a wiser option for anyone considering long term acne treatment.
