083: Can Magnesium Give You A Rash?

Have you ever tried spraying your skin with magnesium oil spray only to end up super itchy? Or maybe your skin feels like it burns…well, there’s a perfectly good explanation for that. You see, magnesium and skin rash can go hand in hand, unfortunately.  

So while magnesium is a popular supplement suggestion, topical magnesium is another option you’ve likely heard about.

But there can be downsides to using topical magnesium spray that often surprises people because the reaction can potentially cause a significant itchy skin flare-up.

So the question is… is it normal to experience this type of reaction? Can too much magnesium cause itching?

And does it mean that you’re sensitive to something in the spray? Or is it just that magnesium can cause an itchy rash?

In today’s episode, I wanted to explore the relationship between magnesium and skin rash — and why you might want to avoid magnesium oil spray on rashed skin.

Magnesium is critical to the proper functioning of your body and is necessary for over 300 biochemical reactions in your body. It can help you relax and fall asleep while certain forms can have the exact opposite action during the day by waking you up.

If magnesium oil triggers what feels like a rash or a flare, you may want to stop it. Nobody really knows why magnesium oil causes itching or burning. Some people say that this reaction means you’re deficient in magnesium, but there is literally no science to support that claim.

Can Magnesium Give You A Rash? (FULL TRANSCRIPT)

Welcome to Episode #83 of the Healthy Skin Show!

In today’s episode, I want to talk about magnesium.

Here’s the thing with magnesium…

Whenever you have a health issue, it’s one of the first suggestions people will make. When it comes to your skin, magnesium is very important.

But here’s the thing – the form of magnesium that you take matters. It should be specific to your symptoms and issues.

Because this is a bit complicated, I’ll break this topic into two parts. In this article, I will focus solely on topical magnesium.

I’m asking questions like “can magnesium cause a rash?” Or “if you’re getting a rash from a magnesium supplement, what may be a better form than another form?”

Magnesium and Skin Rash

First, it’s worth mentioning a few of the benefits of magnesium.

Magnesium is critical to the proper functioning of your body, especially on a biochemical level.

In fact, it’s necessary for over 300 biochemical reactions in your body.

It can help you relax and wind down at night and fall asleep.

Surprisingly, certain forms can have the exact opposite effect during the day, waking you up.

It can reduce muscle cramps and restless leg syndrome.

And it can also help you poop.

Magnesium and other essential oils

Can Magnesium Oil Help Your Skin?

One of the first suggestions people often make is to apply magnesium oil to your skin to soothe it or increase your body’s magnesium stores.

One reason they suggest a topical form is that certain forms of magnesium can cause gastrointestinal side effects when taken orally.

Magnesium oil seems like a much less risky version of magnesium that can be absorbed through your skin.

Sounds great, right?

There are a couple of problems I have with magnesium oil.

The first issue is related to the quantity of magnesium you’re actually absorbing. If you are truly deficient in magnesium, which I often find in clients, you have no idea how much magnesium your body is actually absorbing through your skin.

There’s no clear way to tell which makes it difficult to know if you’re truly putting a dent in a deficiency.

Can Magnesium Cause A Rash?

The second issue is related to this side effect of using magnesium oil. If you haven’t tried it yet, know that it can cause your skin to become either itchy or feel like it’s burning.

I don’t know about you, but the idea of making my skin itchier or causing it to burn is really not ideal. It’s not a great idea to trigger yourself to start scratching, because once you start, it can be difficult to stop.

If magnesium oil seems to trigger a rash or a flare, you may want to stop using it.

Why Can Magnesium Spray Cause A Rash?

Nobody really knows why magnesium oil causes itching or burning. Some people say that your skin may react if you’re deficient in magnesium. However, there is literally no scientific evidence to support that claim.

A second idea, which seems slightly more plausible, has to do with the differences in pH between the type of magnesium used in magnesium oil and your skin.

These magnesium oil products use Magnesium Chloride.

As you may remember, your skin’s pH level should be around 4.5.

Microbiome dysbiosis (aka. imbalances) can occur on the skin when there is an imbalance in the microbiome, and this can lead to leaky skin.

One factor triggering all of this is a change in your skin’s pH.

According to some articles I’ve found, the pH of Magnesium Chloride is around 7.5, whereas others put it closer to a pH of 6. Either way, that’s a pretty sizable pH jump from 4.5 and could be disruptive.

However, there is no research on this, so this might not be the reason why magnesium oil causes your skin to itch or burn.

Magnesium And Skin Rash: What About Epsom Salt For Your Skin Instead?

All is not lost if you’d still like to get magnesium through your skin!

Epsom salt, which contains Magnesium Sulfate, is a little bit closer to the natural skin pH — around 5.5 to maybe 6.5.

Maybe that partially explains why Epsom salt baths do not seem to trigger the same type of reaction as magnesium oil.

Don’t Suffer With A Rash From A Magnesium Supplement

My suggestion?

Ditch the magnesium oil, especially if it causes itching and burning.

And definitely don’t spray it directly onto rashes if you find that the area becomes more irritated.

Instead, try a magnesium bath using Epsom salt in warm water, rather than bleach baths (which aren’t actually effective, based on current research).

You can also add some colloidal oats. Click here for the directions on how to make your own colloidal oats.

And you can even add some of your favorite oil to the water. You can use a little drizzle on top of the water’s surface before getting into the bath to help support your skin.

Good options include avocado oil, hemp seed oil, or jojoba oil. For wintertime, heavier oils like sesame seed oil and beef tallow could also work.

The magnesium that dissolves in the bath water will be absorbed through the skin.

So, if you know for sure that your magnesium stores are low, the ideal situation is to use a combo of magnesium baths and supplementation.

Can You Get A Rash From Magnesium?

Magnesium can be a wonderful thing, but you have to make sure you’re taking the right form for you. That way, you don’t end up with GI problems like diarrhea, bloating, and gas.
