That unique sensation is your body talking to you. It's less of a complaint and more of a conversation. For most people, that sting or itch comes down to one of these three things.
1. It’s a Strong, Concentrated Brine
This is the most direct reason for the sting. You've probably heard topical magnesium called "magnesium oil," but it isn't an oil at all. It’s a highly concentrated solution of magnesium chloride, which feels a lot like a strong salt brine on your skin.
Think about the sharp sting you feel when salty seawater gets into a tiny, invisible paper cut. Your skin is experiencing something very similar. The magnesium in our Daily Spray is harvested directly from pristine Australian salt lakes, giving it a natural potency. This sensation is often more noticeable if your skin is dry, sensitive, or has tiny micro-abrasions you can't even see, especially after shaving.
2. Your Body Is Genuinely Thirsty for It
Here’s where it gets interesting. That powerful tingle can actually be a sign that your body's magnesium levels are on the lower side.
A simple way to think about it is that calcium acts like the accelerator pedal for your nerves, while magnesium is the brake. When you're low on the brake (magnesium), the accelerator can get a bit stuck, making your nerve endings jumpy and over-sensitive.
When you apply magnesium directly to your skin, it gets to work quickly. That sudden rush of a much-needed mineral can fire up those sensitive nerve endings, creating that signature tingle. The good news? Most people find the sensation fades within a week or two of regular use as their body’s levels top up and their nervous system calms down.
3. It’s a Little Cellular ‘Spring Clean’
Another way to look at that itch is as a temporary cleansing reaction. Magnesium is a master mineral for cellular health, helping manage what comes into our cells and what goes out.
Some theories suggest that as magnesium enters the cells, it can help push out other things that don’t belong there. As these substances make their way out through your skin, they can cause some temporary surface irritation. It’s like tidying up a dusty room; things can get a bit stirred up before everything settles down and feels calm.
