The declare
Lovers declare that magnesium lotion — particularly utilized to ft — can enhance sleep. Many additionally argue it may be utilized all around the physique to treatment a wide range of different well being illnesses.
Persons are shopping for the thought, actually. One market analysis group estimated the market in 2024 for topical magnesium was greater than $400 million.
The proof
There’s little proof that magnesium may be absorbed by way of the pores and skin.
“The issue with that is that the pores and skin is a barrier, not a sponge,” says Nicholas Theodosakis, a dermatologist and researcher at Harvard College.
Most drugs are greatest delivered orally, which permits for fast absorption into the bloodstream. A number of varieties of drugs are nicely suited to absorption by way of the pores and skin, he says. Usually, transdermal patches are used for drugs that have to be slowly absorbed over time.
There is no proof that magnesium is on this class.

Regardless of the dearth of proof, no less than one physician says if magnesium lotion is working for you — go for it. “I believe the dangers of making use of magnesium to your pores and skin are most likely extraordinarily small,” says Dr. John Winkelman, a sleep skilled at Harvard.
He says he had no less than one affected person report utilizing “magnesium butter,” for sleep. (“ I believed you set that on toast, however no, in truth, you rub it in your legs,” says Winkelman.) “She did say magnesium butter was serving to.”
Winkelman says in issues of sleep particularly, placebo may be highly effective — and he isn’t one to discourage no matter secure cures work for his sufferers.
That mentioned, Winkelman will not be planning to suggest it anytime quickly. Dietary supplements and associated merchandise should not regulated by the Meals and Drug Administration, which leaves shoppers susceptible to purchasing the lotion with out understanding precisely what’s in it.
For a few of the sleep situations that magnesium lotion supposedly treats, says Winkelman, there are medically confirmed remedies. Stressed legs syndrome, for instance — one thing some influencers say is eased with an software of magnesium lotion — has precise examined medical therapies.
“I actually do not feel that it is truthful to suggest issues that I actually do not suppose have been substantiated as efficient,” says Winkelman. “I am a giant believer in scientific proof.”
The underside line
Although there isn’t a proof that magnesium lotion promotes sleep or addresses medical issues, consultants, together with dermatologist Nicholas Theodosakis, agree that magnesium lotion probably will not damage, besides, he says, “within the pocketbook.”
He notes that as a dermatologist, he sees many well being fads. “I believe it is simply the character of pores and skin,” he notes. “It is extremely linked to emotional well-being and psychology and tradition. Additionally, you simply have numerous it.”
