The thirty-second
ritual.
A single-active magnesium roller for the nights you actually want to sleep. Three rolls. Two deep breaths. Lights out.

01 — The Object
A tube to peel.
A tube to peel.
A bottle to keep.
Nothing else in the box.
The peel-tab moment
Lift the silver foil and a hidden line is waiting on the underside: begin the ritual. A small reveal — the kind of detail that says we thought about the second after you opened it.
10ml frosted glass
Medical-grade frosted glass with a brushed silver anodised aluminium cap and a 6mm stainless rollerball. Cool to the skin. Glides without dragging. Refillable in spirit, not in machinery — order another when this one’s done.
Three ingredients. One active.
Distilled water, Zechstein magnesium chloride, vegetable glycerin. The back label is one line. Read it in three seconds — and find nothing hiding.
02 — The Ritual
Three rolls.
Three rolls.
Two deep breaths.
Lights out.
Pulse points.
Inside the wrists. The base of the neck. Behind the ears. The soles of the feet. Anywhere the skin is thin and the blood is close.
Before bed.
Or after training. Or on a long flight. Or before a presentation. The ritual is portable because the bottle is — 10ml fits anywhere.
Every day.
Formulated for daily use at the gentler 10% concentration. No skip days, no cycling, no protocol. The cadence is yours.
03 — The Science
The mineral your body
The mineral your body
runs on — and
runs low on.
Magnesium is a required cofactor in more than 300 enzymatic reactions — muscle function, nerve transmission, the sleep–wake cycle, the body’s cortisol and stress response, and the conversion of food into usable energy. It’s the fourth most abundant mineral in the human body.
Yet around half of adults in the West fall short of the recommended daily intake. Stress, caffeine, alcohol and intense training quietly deplete it — in exactly the women who can least afford to run on empty.
Reova brings it back into contact with your body through the largest organ you have. Magnesium chloride from the Zechstein seabed — sealed 1,500 metres underground for 250 million years — at the gentler 10% dose, with 1% glycerin to keep skin conditioned. No fragrance. No preservative. No filler. Nothing else that does anything else.

What magnesium does in the body
Muscle function
Central to normal muscle contraction and relaxation — the natural counterpart to calcium in the muscle cell.
Nervous system
Supports nerve transmission and the calming neurotransmitters that quiet an overactive system, including GABA.
Sleep & rest
Involved in the melatonin and circadian pathways that govern how the body transitions toward rest.
The stress axis
Part of the HPA axis behind the cortisol response — and stress, in turn, depletes it, which becomes a cycle.
Energy & metabolism
Every molecule of ATP — the body’s energy currency — must bind a magnesium ion to become biologically active.
Bone structure
Around 60% of the body’s magnesium is held in bone, contributing to structural integrity alongside calcium.
A note in good faith: Reova is a cosmetic for external use. The above describes magnesium’s role in the body generally — it is education, not a promise to treat any condition.
04 — Through the Skin
Why a roller,
Why a roller,
not a pill.
The skin is the body’s largest organ, and transdermal mineral delivery is an active area of research. Magnesium chloride is among the most water-soluble and skin-compatible magnesium salts — which is why it’s the form used in topical magnesium products worldwide.
We’ll be straight with you: the science on how much magnesium absorbs through skin is still emerging, and we won’t pretend otherwise. What is well established is that magnesium chloride applied to the skin is well tolerated, that the ritual of application supports a genuine sensory wind-down, and that a roller delivers it precisely to pulse points — wrists, neck, behind the ears — where skin is thin and the moment becomes a ritual rather than a chore.
A roller is also simply more honest to real life than a bath. Not everyone has a bath. Everyone has thirty seconds before bed.
05 — Safety
Made for the skin
Made for the skin
that reads every label.
“We didn’t formulate the Roller for the easy customer. We formulated it for the customer who reads every label twice — the pregnant, the postpartum, the chemically sensitive. If the formula passes her test, it passes everyone’s.”
— Founder’s note- Single active. Magnesium chloride. The other two ingredients are water and a humectant — neither does anything actively to your body.
- Fragrance-free. No essential oils, no synthetic fragrance compounds, no “natural parfum.” The bottle smells of nothing.
- 10% concentration — the gentler dose. The industry standard is 15-20%. We picked the dose that respects sensitive skin and still works.
- Formulated to be suitable during pregnancy. Consult your healthcare provider before use.
- Patch test before first use. Mild tingling on the first 5-10 applications is normal and subsides as your skin adjusts.
- UK SCPN registered. Independent cosmetic safety report on file for every batch.
