Why Does Magnesium Spray Tingle on Your Skin?

First night with a magnesium spray, most people feel it: a light tingle, sometimes an itch, where the mist landed. It surprises people. It's also the single most common question we get, so here's the straight answer.

The tingle is your skin reacting to a concentrated mineral salt solution sitting on it. Magnesium chloride at effective concentrations is simply a lot saltier than anything your skin usually meets. Nerve endings notice. People with drier skin, freshly shaved skin, or lower magnesium intake tend to feel it more, and the sensation is strongest the first week or two of use.

How to make it milder

If the tingle bothers you, you have easy options:

• ✦Start on the soles of your feet, the least sensitive spot, and work up to calves and shoulders as your skin adjusts
• ✦Apply to fully dry skin; damp skin concentrates the sensation
• ✦Rub it in rather than letting it sit wet
• ✦Dilute your first week: spray into your palm with a little water or lotion, then apply
• ✦Use fewer sprays and build up gradually

When it's not just a tingle

A mild, fading tingle is normal. Real burning, redness that lasts, or any reaction on broken skin is your signal to stop, rinse, and either dilute heavily or skip that area. Never apply magnesium spray to cuts, cracked heels, or freshly shaved skin, and keep it away from your eyes.

For most people the tingle fades to nothing within a couple of weeks of nightly use. At that point it becomes what it was supposed to be all along: a two-minute ritual you stop thinking about, and sleep you start noticing.
