THE SCIENCE

World-first research, built into every swim.

Can magnesium in water actually pass through the skin?

The research demonstrated that magnesium ions can permeate the human skin barrier and found that the extent of permeation was influenced by magnesium concentration and exposure time - findings that shaped a magnesium-rich, deliberately balanced multi-mineral blend.

Those findings didn’t just support the science behind MagneGlow.

They helped shape the formulation itself.

FROM RESEARCH TO FORMULATION

The science informed what went into the water.

Four findings. Four formulation decisions.

01

A RESEARCH-BACKED FOUNDATION

Magnesium can pass through the skin.

Fluorescent imaging demonstrated magnesium ions within treated human skin tissue, providing direct evidence of magnesium permeation under the conditions studied.

That established the scientific foundation for making magnesium central to MagneGlow.

MAGNESIUM IONS OBSERVED WITHIN TREATED SKIN TISSUE

Fluorescence image of untreated human skin showing little magnesium signal — BEFORE Skin not treated with magnesium. Little fluorescence.

Fluorescence image of human skin after 30 minutes in magnesium solution, with bright signal into the tissue — AFTER 30 MINUTES Treated with magnesium solution. The glow shows magnesium in the skin.

Fluorescence microscopy of human skin. The brighter the glow, the more magnesium present. Skin exposed to 5 mM MgCl₂ solution for 30 minutes showed increased fluorescence compared with untreated skin.

A MAGNESIUM-RICH FORMULA BY DESIGN

Concentration matters.

The research found that magnesium permeation changed according to the concentration of magnesium in solution.

So MagneGlow wasn’t developed simply to contain magnesium.

It was developed to be magnesium-rich.

33%

More magnesium. By design.

MagneGlow contains 33% more magnesium in ionic form than comparable mineral pool products.*

*Based on US comparative market research of similar mineral pool products. Comparison refers to magnesium in ionic form.

PERMEATION CHANGED WITH THE CONCENTRATION OF MAGNESIUM IN SOLUTION

Fluorescence image of human skin after 15 minutes in 52 mM magnesium chloride, showing low signal — LOWER CONCENTRATION 52 mM magnesium solution, 15 minutes. Little fluorescence.

Fluorescence image of human skin after 15 minutes in 1.9 M magnesium chloride, showing bright signal — HIGHER CONCENTRATION 1.9 M magnesium solution, 15 minutes. Bright fluorescence.

Same exposure time, different concentration. At the higher concentration, magnesium was visible in the skin within 15 minutes; at the lower concentration it appeared only after 60 minutes.

A SWIMMING ENVIRONMENT DESIGNED FOR IMMERSION

Exposure matters.

The research also showed that magnesium permeation changed according to how long the skin was exposed to the mineral solution.

That makes the swimming environment uniquely relevant.

You don’t apply MagneGlow for a few seconds.

You swim in it.

Every lap, float and moment in the water becomes time spent immersed in the mineral environment.

PERMEATION CHANGED WITH HOW LONG THE SKIN WAS EXPOSED

Fluorescence image of human skin after 5 minutes in 52 mM magnesium chloride, showing little signal — SHORTER EXPOSURE 5 minutes in 52 mM magnesium solution. Little fluorescence.

Fluorescence image of human skin after 60 minutes in 52 mM magnesium chloride, showing bright signal — LONGER EXPOSURE 60 minutes in the same solution. Clear fluorescence along the skin.

Same concentration, different exposure time. The longer the skin stayed in the solution, the more magnesium was visible in it.

A DELIBERATELY BALANCED MINERAL BLEND

More than magnesium.

MagneGlow combines magnesium with complementary minerals and trace elements including:

Mg

Magnesium

Supports normal muscle function, relaxation & healthy skin. Research demonstrated magnesium permeation through the skin, while magnesium is widely studied in relation to skin function, muscle activity and relaxation.

K

Potassium

Supports fluid balance & muscle function. Potassium is involved in normal cellular function, fluid balance and electrical signaling throughout the body.

Na

Sodium

Supports salinity & salt-system use. Sodium contributes to salinity and salt-system function, while also being an electrolyte involved in fluid balance and nerve signaling.

B

Boron

Assists in mineral metabolism. Boron has been studied in relation to mineral retention, including magnesium and calcium.

I

Iodine

Supports normal thyroid function. Iodine is involved in normal thyroid function, and research referenced during development has demonstrated skin permeability to iodine.

Existing research referenced during development has also investigated skin permeability to minerals including potassium, sodium, iodine and boron, which is why MagneGlow takes a broader multi-mineral approach rather than focusing on magnesium alone.

WHY THE FORMULATION MATTERS

It isn’t simply about adding minerals to pool water.

The research showed that what is in the water, how much is present and how long the skin is exposed all matter.

MagneGlow takes those findings and turns them into formulation decisions:

Magnesium-rich by design.

A balanced multi-mineral system.

Designed for the environment you spend time immersed in.

That’s the difference between adding magnesium to a pool and developing mineral water around science.

THE SCIENCE OF SKIN + RECOVERY

The research goes beyond permeation.

Skin + Hydration

Research referenced during development found that aqueous magnesium increased expression of filaggrin, a protein involved in normal epidermal function and the formation of natural moisturizing factors that help skin retain water.

This provides part of the scientific rationale for making magnesium-rich water central to the MagneGlow experience.

Muscle + Relaxation

Magnesium also plays an important role in normal muscle activity, and research referenced during development has investigated its relationship with muscle relaxation.

That is part of why magnesium has become so closely associated with recovery, relaxation and physical wellbeing.
