Beauty bloggers and internet makeup gurus are going to flog me for this one – but milk of magnesia isn’t good for acne. It doesn’t treat acne; it doesn’t clear acne. In fact, I’m hard-pressed to say it does much of anything for the skin.
I know, I know… many people are touting the benefits of milk of magnesia. But before you go hanging your acne-clearing hopes on milk of magnesia, let’s take a
look at the research.
What the heck is milk of magnesia anyway?
Milk of magnesia is an over-the-counter medication for constipation. Yes, it’s a laxative. It’s used to treat gas and indigestion,too.
The active ingredient in milk of magnesia is magnesium hydroxide. It also contains water and sodium hypochlorite.
What does the research say?
The idea that milk of magnesia clears acne probably comes from a letter that was published in the Archives of Dermatoloy back in the 1970’s. The author of the letter said he had been getting good results with his acne patients by prescribing topical milk of magnesia along with 250 mg of oral tetracycline.
So, even though I find it intriguing, the letter just stated one dermatologist’s experience; it isn’t a formal study of any kind. It’s also very possible that the antibiotics alone were causing the improvement of acne, not the milk of magnesia.
There have been no formal studies done on milk of magnesia and its effects on acne acne. So, any source
that claims milk of magnesia has been proven to clear acne just isn’t accurate.
Can milk of magnesia reduce oily skin?
Another (rather old) study, published back in the 80’s shows that magnesium hydroxide is a darn good degreaser. It could break down the oil on the skin’s surface, leaving your skin looking more matte.
Milk of magnesia doesn’t reduce sebum production, though. Meaning, it won’t make your oil glands produce less oil. It just removes oil on skin’s surface.
But since acne isn’t caused by oil on the surface of the skin, that alone won’t be enough to clear up acne. Acne is actually caused by a host of different factors. (To find out exactly why your skin is breaking out, check out this article: What Really Is Causing Your Acne.)

Are you going to harm your skin if you use a milk of magnesia mask? Probably not (although for some people it can cause contact dermatitis.) It just isn’t a great acne treatment. If it was, I’d personally hand out bottles of the stuff.
There are plenty of other options out there, though, that can deliver much better results.
