Milk of Magnesia for Skin Rash and Eczema Problems

There are also stories galore of people using milk of magnesia for skin rash as well as eczema problems.

According to the Style Craze website, milk of magnesia – thanks  to its anti-acid properties – helps to improve skin rashes by neutralizing the acids often responsible cause an eruption of the rashes especially among oily skinned people. It in addition acts as a disinfectant and can in so doing help to curb the spread of a rash.

I spent some time reading about common skin rashes that may benefit from milk of magnesia on skin and poison ivy and eczema skin problems in particular stood out very prominently. For eczema problems, the positive benefits of MoM are attributed to its disinfectant properties.

Some people even use milk of magnesia to relieve diaper rash in their children by keeping the skin dry, soothed and free of bacteria thanks to its antibacterial properties. Moms have reported success with applying milk of magnesia alone onto their baby’s bottom but if you like you can as well mix it with a good lotion such as aquaphor or even add some talcum powder to create a smooth paste.

As beneficial as using milk of magnesia for skin rash and eczema treatment may be, you should keep in mind that it has a knack for causing particularly dry skin. This might not work well for people with naturally dry skin who might end up with a face that feel very tight. For this same reason, you should not use milk of magnesia for skin to replace your daily face wash.

Lastly, if you are allergic to magnesium (or any other ingredient in MoM for that matter), you are better off staying away from milk of magnesia as it is mostly magnesium hydroxide.

Applying milk of magnesia for skin improvement in individuals with oily skin has quick turnaround in as far as oil absorption is concerned and can give your skin a matte feel in just a few minutes, but as most skin care experts warns, it could lead to proliferation of bacteria and viruses as well as numerous pathogens on the skin if used over a long period of time or repeatedly.

This is because the alkaline nature of the milk of magnesia destroys the otherwise beneficial acidic film on the skin called acid mantle. This film helps to maintain an acidic environment that is suitable for growth of beneficial bacteria found on the skin (commensals) while discouraging the growth of harmful bacteria and viruses among other organisms.

When the acid mantle is destroyed, thanks to prolonged or frequent use of MoM, the resulting alkaline pH could lead to a proliferation of harmful bacteria, leading to a whole lots of skin problems including acne outbreaks.

Milk of magnesia is also linked to several other side effects including tightness and dryness when either too much of it is applied or is used by people with naturally dry skin, contact dermatitis with prolonged use, poor exfoliation of dead skin cells, lower extracellular lipid processing, and reduced overall skin integrity as the Future Derm points out.

For oil reduction, it is advisable to only use milk of magnesia sparingly and for a short period of time lest you reverse the benefits and end up making milk of magnesia bad for your skin. For example, you should apply it when you have a special occasion e.g. a photo shoot or a wedding, to keep your face matte.

As for acne treatment, use MoM only if you are not allergic to magnesium and have oily skin.
