Milk of magnesia, a compound also known as magnesium hydroxide, is used temporarily to relieve constipation and other symptoms caused by excess stomach acid. It's a laxative that draws water into the intestines to help lower the amount of acid in the stomach and lets the stool pass more easily. Milk of magnesia is taken in chewable or liquid form. While it's ideal for providing short-term constipation relief, there are also many other uses for the laxative, and it poses little to no risks when the body absorbs it.
Milk of magnesia's alkaline nature absorbs oil helping prevent acne on the face of individuals who suffer from oily skin. It also has antibacterial qualities that disinfect and kills the bacteria that cause acne. Furthermore, milk of magnesia contains zinc that balances hormones and speeds up wound healing.
There are several ways individuals can use milk of magnesia to treat acne-prone skin. For the best results, individuals should use milk of magnesia as a mask by applying a thin layer of the liquid form on the skin and let dry. It will cause the skin to tighten as it is absorbing the excess oil. Once dry, remove the milk of magnesia with warm water. Thankfully, milk of magnesia can also be used as a spot treatment for the occasional pimple when left to dry overnight.
