At a glance
Insufficient
evidence for magnesium on the skin (oils, sprays, flakes, lotions)
Our honest take
A magnesium chloride spray marketed for joints. We make no claims about joints or joint conditions, and there is little good evidence that a useful amount of magnesium passes through the skin. If you have joint pain, speak to your GP or pharmacist; if you want more magnesium, an oral supplement is the route with evidence behind it.
- You like using a spray as part of a massage routine
- You understand it is not a proven treatment for anything
- You have joint pain or swelling: see your GP or pharmacist instead
- You have sensitive, broken or freshly shaved skin: it often stings
- You react to essential oils or fragrance
The science
Magnesium on the skin (oils, sprays, flakes, lotions)· evidence: Insufficient
Magnesium sprays, oils, lotions and bath flakes are usually magnesium chloride (or sulfate) in water. They are sold on the idea that magnesium soaks in through the skin. Reviews of the research have found very little good evidence that a meaningful amount does: the skin is a strong barrier, and the few small studies are poor quality and inconsistent.
A warm bath or a massage may feel good in its own right, but if you want to raise your magnesium intake, magnesium from food or an oral supplement is the route with evidence behind it. Claims about sleep, muscles, joints or stress for these products are not authorised.
Typical dose: No established dose. Use as directed on the pack.
Safety: Magnesium chloride sprays often tingle or sting, especially on freshly shaved or broken skin; rinse off if irritation persists. Do not swallow. Keep away from eyes.
