More people are discovering magnesium through skin conditions. Here's what we know, what we don't — and which format actually makes sense for each situation.
More and more people are finding their way to magnesium through an unexpected door: not because a doctor prescribed it, but because they read about it in an eczema forum, a friend swore by it, or they exhausted other options and decided to dig deeper.
They're right to investigate. Magnesium plays a role in skin health that mainstream dermatology underappreciated for years — but that now has enough research behind it to take seriously. This guide explains what we know, what we don't, and which magnesium format makes the most sense depending on your specific situation.
Why Does Magnesium Affect the Skin?
The connection between magnesium and skin isn't immediately intuitive — but it has solid biological logic. Magnesium:
- Regulates inflammation: It's a cofactor for enzymes that control key inflammatory pathways. Magnesium deficiency is associated with elevated inflammatory markers like C-reactive protein (CRP) and interleukin-6 (IL-6) — the same markers elevated in eczema and psoriasis.
- Modulates immune response: Skin conditions like eczema and psoriasis have significant immune components. Magnesium participates in T-lymphocyte regulation and the Th1/Th2 balance that is central to both conditions.
- Supports the skin barrier: Magnesium is essential for the synthesis of structural skin proteins and for the correct function of lipids in the skin's barrier layer. A compromised skin barrier is the primary trigger for eczema flares.
- Lowers cortisol: Chronic stress worsens nearly every inflammatory skin condition. Magnesium helps regulate the HPA axis, reducing cortisol production — which explains why stress triggers flares, and why magnesium may help buffer them.
Magnesium and Eczema: Does It Work?
Eczema (atopic dermatitis) is a chronic inflammatory condition characterized by dry skin, intense itching, and flare-ups. It affects 10–20% of children and 1–3% of adults worldwide.
What does the research show?
Several studies have found that patients with atopic dermatitis have lower serum magnesium levels than people without eczema. While this doesn't prove direct causation, it's consistent with the mineral's known anti-inflammatory and immune-modulating roles.
Transdermal magnesium deserves particular attention here. The mineral-rich waters of the Dead Sea — famous for their skin benefits — have been formally studied in atopic dermatitis. Research from the University of Kiel showed that bathing in Dead Sea salt solution (rich in magnesium chloride) significantly improved skin hydration, reduced inflammation markers, and decreased itching in eczema patients.
Does oral magnesium help eczema?
Oral magnesium can help indirectly: by reducing systemic inflammation, improving sleep quality (which reduces nighttime scratching), and modulating immune response. However, the most directly documented skin benefits come from transdermal magnesium applications.
A note on "magnesium cured my eczema": You'll see this claim in searches and forums. Magnesium does not cure eczema — eczema is a chronic condition with genetic and environmental components. What magnesium can do is meaningfully reduce inflammation, improve skin barrier function, and ease symptoms, which is valuable even if it's not a cure.
Can magnesium cause eczema?
No — magnesium doesn't cause eczema. However, some transdermal magnesium products (particularly undiluted magnesium chloride oil) can cause temporary skin irritation on very sensitive skin. This is a contact reaction, not eczema — it resolves by diluting the product or switching to a formulated cream or lotion instead.

Psoriasis is an autoimmune condition that accelerates the skin cell renewal cycle, causing scaly plaques, redness, and inflammation. It affects approximately 2–3% of the global population.
The magnesium-psoriasis connection
Psoriasis is characterized by elevated pro-inflammatory cytokines — particularly TNF-α, IL-17, and IL-23. Magnesium inhibits the activation of NF-κB, one of the master regulators of these inflammatory pathways. In practical terms: magnesium can help "turn down the volume" on the exaggerated inflammatory response that characterizes psoriasis.
Multiple studies have found magnesium deficiency more prevalent in psoriasis patients than in the general population, suggesting that supplementation may have a therapeutic role alongside standard dermatological treatment.
Which magnesium is best for psoriasis?
Magnesium glycinate (oral): The most studied form for inflammatory conditions. The glycine component also has independent anti-inflammatory properties. Typical adult dosage is 200–400 mg of elemental magnesium per day. See the full Val Magnesium Glycinate 325 mg for a high-absorption option.
Transdermal magnesium cream: For localized plaques on knees, elbows, or scalp, topical application delivers magnesium directly to the affected area. The Val Transdermal Magnesium Cream is formulated specifically for this purpose.
Magnesium salt baths: Warm baths with magnesium chloride or Dead Sea salts are a recognized complement for psoriasis — both for their hydrating effect and for transdermal magnesium absorption.
Important: Magnesium is a complement, not a replacement, for medical psoriasis treatment. It may meaningfully reduce inflammation and improve quality of life, but psoriasis requires proper dermatological management — especially for moderate to severe cases.
Magnesium and Cellulite: Is There a Real Connection?
Cellulite — the "orange peel" texture that appears primarily on thighs, glutes, and abdomen — has a multifactorial cause: connective tissue structure, lymphatic circulation, fluid accumulation, and changes in adipose tissue. How does magnesium fit in?
Four ways magnesium may help with cellulite
- Fluid retention: Magnesium works in balance with sodium and potassium to regulate intracellular fluids. Magnesium deficiency promotes fluid retention, which is one of the factors that worsens the visible appearance of cellulite.
- Circulation and energy metabolism: Magnesium is essential for ATP production and muscle function. Better circulation reduces lymphatic stagnation that contributes to cellulite.
- Connective tissue integrity: Magnesium participates in collagen synthesis and in the function of enzymes that maintain connective tissue integrity. Stronger connective tissue is less likely to show the characteristic texture of cellulite.
- Cortisol reduction: Cortisol promotes abdominal and visceral fat accumulation. Magnesium's cortisol-regulating effect may indirectly influence fat distribution.
Does the magnesium roll-on work for cellulite?
The Val Anti-Cellulite Firming Roll-On has gained significant popularity, combining transdermal magnesium with a massage application that stimulates local circulation. While specific cellulite research is limited, the combination of magnesium + mechanical stimulation has physiological logic supported by what we know about both elements separately. Many users incorporate it as a daily ritual, applied to thighs and glutes in circular massage motions.

This deserves an honest answer. Results vary considerably depending on the condition, the format used, and individual factors:
The consistency principle: A supplement taken irregularly will produce far less predictable results than one taken daily at a moderate dose. With magnesium, consistency matters more than the precise dose within the therapeutic range.

Other Skin Conditions Where Magnesium May Help
Chronic itching (without diagnosed condition)
Unexplained itching can be related to magnesium deficiency and nervous system activation. Magnesium acts as an NMDA receptor antagonist, which may reduce neurologically mediated itch sensations — a mechanism distinct from the anti-inflammatory effects described above.
Migraines with skin sensitivity
Migraines frequently coexist with skin hypersensitivity (allodynia). Magnesium has some of the strongest evidence of any supplement for migraine prevention. The Val Magnesium Roll-On, applied to temples and the back of the neck, is widely used as a complement to oral magnesium for migraine management.
Stress-related skin flares
Chronic stress elevates cortisol, which degrades the skin barrier, reduces collagen production, and worsens virtually every inflammatory skin condition. Magnesium as a stress-axis regulator has direct implications for stress-triggered skin flares — making it relevant for eczema, psoriasis, rosacea, and acne that correlates with stress periods.
Frequently Asked Questions
Magnesium glycinate is currently the most recommended oral form for chronic inflammatory conditions. Its high bioavailability combined with the glycine component (which has independent anti-inflammatory properties) makes it especially relevant for psoriasis. Typical adult dosage is 200–400 mg of elemental magnesium daily.
Magnesium cream can be a useful complement for eczema, particularly for improving skin hydration and reducing localized inflammation. Look for products formulated without harsh preservatives, artificial fragrances, or potential irritants. For children with eczema, the Val Happy Kids cream line is a gentler option.
Yes — through two distinct mechanisms. First, via its anti-inflammatory effects, which reduce the underlying inflammation that causes itch. Second, through NMDA receptor antagonism, which can reduce neurologically mediated itch that occurs even in the absence of visible inflammation. Both topical and oral magnesium may help.
The most practical approach for cellulite combines a transdermal roll-on (applied with massaging motion to stimulate local circulation) and oral magnesium glycinate (to address fluid retention and systemic metabolic factors). Consistency over at least 8–12 weeks is key for visible results.
Magnesium lotion or cream can help with localized psoriasis plaques by providing direct anti-inflammatory support and improving hydration. It's a useful complement to oral magnesium and medical treatment, not a standalone therapy for psoriasis.
No — oral magnesium glycinate does not cause eczema. Some people experience mild digestive upset at higher doses, but skin reactions are not associated with magnesium glycinate taken orally. Undiluted topical magnesium chloride (oil) can occasionally cause contact irritation on very sensitive skin — if this happens, switching to a formulated cream resolves it.
Bottom Line
Magnesium isn't a magic solution for eczema, psoriasis, or cellulite — but it's not a marginal supplement either. The available research, combined with clinical experience and the reports of thousands of people, suggests that magnesium can be an important piece of the puzzle — especially when combined with an integrated approach to skin health.
If you have a chronic skin condition, it's worth exploring whether magnesium could be part of your solution — starting with a conversation with your dermatologist and choosing a quality supplement in the format that makes the most sense for your specific situation.
