02 / Ideal for
One jar.
Many moments.
Designed for people who want targeted topical magnesium with a moisturizing, non-greasy feel — not a spray, not a soak, just a scoop and a massage.
Active Days
Popular among athletes and active people for post-workout massage to calves, thighs, shoulders, and arms — areas that feel tight after training.
Evening Wind-Down
A small scoop massaged into the soles of the feet and calves 20-30 minutes before bed fits naturally into an unwinding routine.
Tight Spots
Neck, shoulders, calves — anywhere everyday tension shows up. Targeted application with a fast-absorbing finish that does not stain clothes.
Clean-Ingredient Shoppers
Only 4 ingredients — magnesium chloride, shea butter, coconut butter, and beeswax. No artificial fragrance, parabens, phthalates, or fillers.
Sensitive Noses
The light, naturally warm scent comes only from the shea and coconut butter — a good fit if synthetic perfumes bother you or you prefer fragrance-free body care.
Travel-Friendly
No mixing, no spray bottle, no risk of leaking liquid in a carry-on. A compact glass jar that fits a daily routine on the road.
03 / Why this one
Four ingredients.
Done with intent.
Most magnesium lotions carry 20 to 40 ingredients — synthetic fragrances, fillers, preservatives. This cream is built around what actually earns its place.
USP
Pharmaceutical-grade magnesium chloride.
The active ingredient is USP-grade magnesium chloride sourced from the Dead Sea — the same raw material we sell in our flake and powder formats. USP grade is a purity standard; we use the same material in topical and bath products across the line.
🌊
Sourced from the Dead Sea.
Magnesium chloride refined from the mineral-dense brines of the Dead Sea, a source long associated with high natural magnesium content and wellness traditions worldwide.
✋
Small-batch, hand-poured in Madera.
Made in small batches in our family-operated facility in Madera, California. Smaller runs mean fresher jars, tighter quality control, and less overstock — the same approach we apply across our wellness line.
🫙
Glass jar — reusable, no plastic.
Packaged in a reusable glass jar instead of a plastic pump or tube. Better for product integrity, kinder to the environment, and easy to repurpose when empty.
🌿
No synthetic fragrance.
The light, warm scent comes only from the shea and coconut butter — no added perfumes, parabens, or phthalates. A cleaner fit for sensitive noses and people who avoid synthetic fragrance.
⚗️
Tested for heavy metals.
The magnesium chloride raw material is independently lab tested for heavy metal content. Results are consistently well below required limits — the same testing approach we apply across our wellness line.
04 / The science
Honest about what topical magnesium is — and is not.
18% MgCl₂
USP-grade Magnesium Chloride in a shea-and-coconut base
Magnesium Chloride is an inorganic salt of magnesium and chloride ions. In topical formulations it is highly soluble and integrates smoothly into emulsified creams — which is why it is the standard form used across wellness products that combine magnesium with skin-conditioning ingredients.
This cream carries an 18% concentration of USP-grade magnesium chloride — a meaningful level for a topical body cream while remaining comfortable on most skin types. The chemistry is straightforward: every gram of pure Magnesium Chloride Hexahydrate contains about 120 mg of elemental magnesium (the math: Mg atomic weight 24.305 divided by MgCl₂·6H₂O molecular weight 203.31 ≈ 11.96%). The remaining 82% of the formula is the moisturizing carrier base — shea butter, coconut butter, beeswax, and water.
The science on transdermal magnesium absorption is actively studied and not fully settled. We position this as a topical body cream with a magnesium-chloride active — not as a substitute for dietary magnesium or oral supplementation. What many shoppers do find is that the routine itself — the massage, the cooling-then-warming sensation, the soft skin afterward — is a soothing addition to a daily wind-down or post-activity ritual.
For background on how topical magnesium fits alongside other forms, see Oral vs Transdermal Magnesium: Complete Guide.
Key Ingredients
Four ingredients. Each one earns its place.
Magnesium Chloride USP (MgCl₂·6H₂O) — 18%
The active wellness ingredient. USP-grade purity, Dead Sea sourced. Highly soluble and integrates smoothly into the cream base.
Shea Butter (Butyrospermum Parkii)
A rich, protective emollient that softens and conditions the skin. Provides the cream's cushiony moisture base and its slow-melt feel on contact with warm skin.
Coconut Butter (Cocos Nucifera)
Adds a silky, gliding texture and light nourishment. Helps the cream spread evenly without a heavy, tacky residue.
Beeswax (Cera Alba)
Forms a light, breathable barrier that helps the cream stay where you put it. Also gives the formula its firm-but-spreadable consistency at room temperature.
Full INCI: Magnesium Chloride, Butyrospermum Parkii (Shea) Butter, Cocos Nucifera (Coconut) Butter, Cera Alba (Beeswax), Aqua (Water).
Allergen note: Contains coconut-derived ingredients and beeswax. Not suitable for individuals with known allergies to these ingredients or for shoppers avoiding animal-derived ingredients (this product is not vegan). Patch test on a small area of skin before first full application.

What to Expect
First use: The balm-cream melts on contact with warm skin and absorbs in 2-3 minutes. Some shoppers feel a mild tingling on first applications, especially on sensitive or freshly shaved areas — this typically fades with regular use.
Week 1-2: With consistent daily use, many shoppers describe target areas as feeling more comfortable and the evening application becoming a familiar wind-down cue.
Month 1+: The routine settles in. Skin in the applied areas tends to stay softer, and the daily ritual itself becomes the reliable part — useful whether or not transdermal absorption is part of the effect.
05 / How to use
Scoop.
Massage.
Done.
A simple cream with three favourite use patterns. Pick the one that fits your routine.
Daily Targeted Application
Quick answer: Pea- to dime-sized scoop per area; massage in for 2-3 minutes. Up to 2-3 times per day on the same area.
- Scoop a pea- to dime-sized amount onto clean, dry fingertips.
- Warm briefly between hands — the beeswax base softens quickly with body heat.
- Massage into the target area using small circular motions until fully absorbed (about 2-3 minutes).
- No rinsing or wiping needed. Reapply through the day as the routine calls for it — typically once or twice per area.
Suggested Application Areas
- 💪 Arms and biceps after upper-body training
- 🦵 Calves and thighs after running or leg days
- 👣 Feet and arches — a popular evening choice
- 💆 Neck and shoulders for everyday tension
- 🤲 Hands as an overnight conditioner
Tip: A little goes a long way. Using more than a dime-sized scoop per area does not noticeably increase results — it just reduces how long the jar lasts.
Evening Wind-Down Routine
Quick answer: Apply generously to the soles of the feet and calves 20-30 minutes before bed.
- Wash and dry your feet and lower legs.
- Scoop a generous pea-sized amount per foot and a dime-sized amount per calf.
- Massage into the soles, arches, ankles, and calves — slow circular motions for 2-3 minutes per area.
- Put on cotton socks if desired (helpful for keeping sheets clean and extending the warming sensation).
- Continue your normal wind-down routine — many shoppers find this becomes a familiar pre-bed cue.
Tip: Many shoppers find the feet a comfortable starting place for topical magnesium because the skin there is thicker and less sensitive. For background on this routine, see Benefits of Magnesium Oil on Feet.
Post-Workout Massage
Quick answer: After a shower, massage a dime-sized scoop into each worked muscle group.
- Wait until after your post-workout shower so skin is clean and pores are open.
- Pat skin mostly dry (a small amount of residual moisture is fine).
- Scoop a dime-sized amount per muscle group — calves, quads, hamstrings, shoulders, etc.
- Massage in firmly for 2-3 minutes per area, using kneading and circular motions.
- Let absorb fully before dressing.
Tip: For larger surface areas, the Magnesium Oil Spray covers ground faster; for full-body soaking, see Epsom Salt or Magnesium Chloride Bath Flakes.
06 / Directions
Patch test.
Start small.
Make it routine.
A short four-step approach for your first jar. Skip nothing on the first day.
-
01
Patch test first.
Apply a pea-sized amount to the inner forearm and wait 24 hours. Continue only if no redness, itching, or irritation occurs. This applies especially if you have sensitive skin or known allergies to coconut or beeswax.
-
02
Start on the feet.
The skin on the soles is thicker and less sensitive — a comfortable place to learn the cream's feel before moving to calves, neck, or shoulders. A mild tingling on first uses is common and typically fades with regular use.
-
03
Use a small amount.
Pea- to dime-sized per area is enough. Massage in for 2-3 minutes until fully absorbed. No rinsing. A little goes a long way — the jar should last 2-3 months at daily targeted use.
-
04
Keep it consistent.
Whichever method fits your day, regular use tends to outperform sporadic heavy application. Most shoppers find a consistent evening or post-workout pattern fits naturally and becomes a useful daily cue.
Good to Know
For external use only. Avoid eyes and mucous membranes. Do not apply to broken, irritated, sunburned, or freshly shaved skin. If you are pregnant, nursing, or have a medical condition, consult your healthcare provider before adding a new topical to your routine.
For external use only. Discontinue use if irritation occurs.
07 / Compare
Magnesium Cream
vs. typical magnesium lotion.
An honest side-by-side. Most "magnesium lotions" on shelves are conventional body lotions with a small magnesium addition.
| Feature | Magnesium Cream (this product) | Typical Magnesium Lotion | Best For | Notes |
|---|---|---|---|---|
| Magnesium Source | USP-grade, Dead Sea origin | Origin often unspecified | Shoppers verifying source | USP is a purity standard, not a use designation |
| Ingredient Count | 4 ingredients | Commonly 20-40+ | Clean-ingredient shoppers | Fewer ingredients = fewer sensitization risks |
| Fragrance | No synthetic fragrance — only natural shea/coconut scent | Often contains added perfume | Sensitive noses | Synthetic fragrance is a common skin sensitizer |
| Texture | Balm-cream — melts on skin, fast-absorbing | Variable; can feel heavy or tacky | Daily-use comfort | Beeswax base gives the firm-but-spreadable feel |
| Packaging | Reusable glass jar | Typically plastic pump or tube | Lower-plastic households | Glass keeps the product stable longer |
| Production | Small-batch, hand-poured in Madera, CA | Mass-produced | Quality control | Smaller runs = fresher jars |
08 / Decision
Is this the right
topical magnesium for you?
A short fit-check so you can decide quickly.
A Great Fit If You
- Want targeted application to a specific area, not whole-body coverage
- Prefer a cream texture with skin-conditioning ingredients over a thin spray
- Are building an evening wind-down routine and want a simple ritual cue
- Avoid synthetic fragrance and prefer clean, short ingredient lists
- Travel often and want a no-leak, no-mix format
- Already use bath flakes or oil spray and want a complementary cream for daytime use
Consider Another Option If
- You want whole-body coverage in one go — try Epsom Salt or Magnesium Chloride Bath Flakes for soaks
- You want a fast, no-residue spray application — try Magnesium Oil Spray
- You want to prepare your own DIY topical magnesium oil or use bulk magnesium chloride — try Magnesium Chloride USP
- You need a vegan-only routine (this cream contains beeswax)
- You have known allergies to coconut-derived ingredients or beeswax
09 / Build the routine
Cream for the day.
These complete the routine.
Many shoppers build a layered routine — cream for targeted daytime use, plus a soak and a spray for coverage and convenience.
Topical
Magnesium Oil Spray
Ready-to-use USP-grade magnesium chloride spray in a glass bottle — for fast, no-cream application to larger areas like legs and back.
Bath SoakMagnesium Chloride Bath Flakes
Larger-format magnesium chloride flakes for bath and foot-soak use. A whole-body soak complements daily targeted cream application. External use only.
Bath SoakEpsom Salt (Magnesium Sulfate)
The classic bath soak. Different chemistry from the cream — a layered weekly soak rounds out a targeted-cream weekday routine.
DIY BaseMagnesium Chloride USP
USP-grade magnesium chloride powder — the same raw material used in this cream — in a bulk format for DIY topical oils, bath soaks, and foot baths.
10 / Safety & handling
Read this before
your first scoop.
A short safety summary. For external use only. Keep out of reach of children and pets.
- Allergens: contains coconut-derived ingredients (Cocos Nucifera Butter) and beeswax (Cera Alba). Not suitable for individuals with known sensitivities to these. Not vegan.
- Patch test before broad use. Apply a pea-sized amount to the inner forearm and wait 24 hours. Discontinue if redness, itching, or discomfort occurs. Avoid eyes, mucous membranes, and broken, irritated, sunburned, or freshly shaved skin.
- Mild tingling on first uses is common with concentrated topical magnesium and typically fades with regular use. Starting on the feet is the most comfortable way to ease in.
- Storage: store in a cool, dry place away from direct sunlight and heat. Keep the lid tightly closed; use clean, dry fingers or a spatula to scoop — avoid introducing water into the jar. Do not freeze.
- First aid: for eye contact, rinse immediately with plenty of clean water for at least 15 minutes and seek medical attention if irritation persists. For skin irritation, wash with soap and water and discontinue use. If ingested, contact Poison Control (1-800-222-1222) or seek medical attention immediately.
- Pregnancy/medical conditions: if pregnant, nursing, or managing a medical condition, consult your healthcare provider before adding a new topical product to your routine.
11 / FAQ
Common questions.
Honest answers.
If your question is not here, contact our team at questions@greenwaybiotech.com.
Why does the cream sometimes feel tingly on first use?
A mild tingling sensation on first applications is common with concentrated topical magnesium products and is generally considered a normal response. It typically fades with regular use as the skin acclimates. Starting on the feet — which are less sensitive — is a popular way to ease in before applying elsewhere. If you experience significant irritation or redness, discontinue use and consult a healthcare professional.
How much should I use per application?
A pea- to dime-sized amount is enough for most targeted areas. A little goes a long way — using more does not noticeably improve results and will reduce how long the jar lasts. At typical daily use, one 4 oz jar provides roughly 160 applications, or about 2-3 months.
How long does one jar last?
With daily targeted use (pea- to dime-sized per area), most shoppers report 2-3 months per 4 oz jar. The number varies with how many areas you treat and how generously you apply. Heavier whole-body application will draw the jar down faster.
Can I use this if I have sensitive skin?
The formula uses only 4 ingredients and contains no synthetic fragrance, parabens, or phthalates — a cleaner option than many conventional body lotions. That said, everyone's skin is different. Patch test on a small area of the inner forearm before broader use, and review the full INCI list if you have known sensitivities to coconut-derived ingredients or beeswax.
Is the magnesium in this cream absorbed through the skin?
The science on transdermal magnesium absorption is actively studied and not fully settled. We position this as a topical body cream with a magnesium-chloride active — not as a substitute for dietary magnesium or oral supplementation. What many shoppers do find is that the routine itself — the massage, the absorption sensation, the conditioned-feel afterward — is a useful and soothing addition to a daily wellness routine. For more context, see Oral vs Transdermal Magnesium.
Is this cream safe to use during pregnancy?
If you are pregnant, nursing, or have an underlying medical condition, please consult your healthcare provider before adding any new topical product to your routine. We are not able to provide medical advice.
Can I use this on my face?
This cream is formulated for the body — muscles, legs, feet, neck, shoulders, hands. The 18% magnesium concentration and beeswax content make it better suited to body skin, which is generally less sensitive than facial skin. For facial routines, a product formulated specifically for the face is a better fit.
What does it smell like?
The cream has a light, naturally warm aroma that comes only from the shea and coconut butter — no artificial fragrance is added. Most shoppers describe it as pleasant and mild, with the coconut scent a little more prominent than the shea. A good fit for people who are sensitive to synthetic perfumes or who prefer fragrance-free body care.
Is this product vegan?
No. The cream contains beeswax (Cera Alba), which is an animal-derived ingredient. If you need a fully vegan magnesium routine, the Magnesium Oil Spray (magnesium chloride and water only) is a good alternative for topical use.
What is the difference between magnesium cream, oil spray, and bath flakes?
All three deliver magnesium chloride topically but suit different patterns. The cream offers targeted application with shea-and-coconut conditioning — best for daily routine on specific areas. The Magnesium Oil Spray covers larger surface areas faster and leaves no cream residue. Magnesium Chloride Bath Flakes and Epsom Salt provide a full-body soak experience. For context on the broader category, see Magnesium Chloride Benefits.
What does "USP grade" actually mean here?
USP (United States Pharmacopeia) grade is a purity standard. A USP-grade material meets pharmacopeial specifications for identity, purity, and contaminant limits — generally tighter than typical food-grade. In this cream, the magnesium chloride active is the USP-grade ingredient; the cream itself is a topical body product, not a pharmaceutical. The same raw material is used in our Magnesium Chloride USP powder and Oil Spray.
Does the cream expire?
Stored properly — cool, dry, lid tightly closed, with clean dry fingers or a spatula used for scooping — the cream stays usable for at least 12-18 months from purchase. Keeping water out of the jar is the biggest factor. The natural shea-and-coconut aroma may shift slightly over time without affecting use.
