How does magnesium help your skin

Could magnesium be the missing link in your skincare routine? Discover the benefits of magnesium for skin health, signs of magnesium deficiency, how magnesium supports collagen production and why magnesium glycinate is often considered one of the best forms for women.

Magnesium is often associated with sleep, stress and muscle health, but this essential mineral also plays an important role in skin health. From supporting collagen production and hydration to helping regulate the body’s response to stress, magnesium influences many of the processes that contribute to healthy-looking skin.

In this guide, we’ll explore the benefits of magnesium for skin, the signs of magnesium deficiency, the different forms of magnesium available and why this often-overlooked nutrient has become increasingly important for healthy ageing.

Why magnesium matters for skin health

Magnesium is involved in more than 300 enzymatic reactions throughout the body.

While many people associate magnesium with relaxation and muscle function, it also contributes to processes that support:

Skin barrier function
Hydration
Collagen production
Cellular repair
Healthy inflammatory responses
Protection against oxidative stress

Because skin is constantly renewing itself, it relies on a steady supply of nutrients to maintain its structure and appearance.

Magnesium helps support these natural renewal processes and may contribute to healthier, more resilient skin over time.

Magnesium deficiency skin symptoms

One of the reasons magnesium has received so much attention in recent years is that many people may not be getting enough of it through their diet.

Magnesium deficiency can affect multiple systems within the body, including the skin.

Common magnesium deficiency skin symptoms may include:

Dry skin
Increased skin sensitivity
Poor skin barrier function
Dull-looking skin
Increased redness
Slower skin recovery
Premature signs of ageing

While these symptoms can have many causes, magnesium deficiency may contribute by affecting hydration, cellular repair and the body’s ability to respond to everyday stressors.

Magnesium deficiency is also associated with symptoms such as:

Fatigue
Poor sleep
Muscle cramps
Headaches
Increased stress
Low energy

Because these symptoms often overlap, many people are unaware that magnesium may be a contributing factor.

Magnesium and collagen: an important connection

One of the most overlooked roles of magnesium is its involvement in collagen production.

Collagen is the most abundant protein in the body and forms the structural framework of the skin, bones, joints and connective tissues.

While collagen supplements often receive the spotlight, the body also requires a range of nutrients to support the natural production and maintenance of collagen.

Magnesium contributes to many of the enzymatic processes involved in protein synthesis and tissue repair.

This means that adequate magnesium levels may help support the body’s ability to maintain healthy collagen-rich tissues.

For women interested in healthy ageing, magnesium and collagen should not be viewed as separate nutrients. They work together as part of a wider network that supports skin structure, resilience and overall wellbeing.

This is one reason why combining a collagen supplement with magnesium-rich foods and targeted nutritional support can be a valuable strategy for supporting skin health from within.

Magnesium, hydration and skin health

Healthy skin relies on hydration. When the body is dehydrated, the skin may appear:

Dull
Dry
Less plump
More prone to fine lines

Magnesium plays an important role in fluid balance and cellular function.

Alongside other electrolytes, magnesium helps regulate the movement of fluids in and out of cells, supporting optimal hydration. This is one reason hydration and magnesium often go hand in hand when discussing healthy skin.

Magnesium and stress: the skin connection

Stress doesn’t just affect how we feel. It can also influence how our skin looks. Periods of prolonged stress may contribute to:

Dullness
Increased sensitivity
Skin flare-ups
Accelerated skin ageing

Magnesium is sometimes referred to as the “relaxation mineral” because of its role in supporting the nervous system. By helping to support relaxation and stress resilience, magnesium may indirectly benefit skin health through its influence on the body’s stress response. A clinical study reviewed in March 2026 revealed that magnesium supplementation supports fibroblast migration, collagen synthesis, and barrier function. It also suggested that there are potential benefits in dermatitis, psoriasis, acne, wound healing and sun protection.

Magnesium and sleep: why it matters for skin

Sleep is one of the most important yet overlooked factors influencing skin health.

During sleep, the body carries out many of its repair and recovery processes. Poor sleep has been associated with: reduced skin barrier function, increased visible signs of ageing, dullness and reduced skin recovery Magnesium contributes to normal nervous system function and helps reduce tiredness and fatigue, which is one reason many people choose to take magnesium in the evening.

Supporting sleep is also one of the reasons magnesium features in formulations designed to promote overnight recovery and wellbeing.

Which magnesium is best for skin?

Not all magnesium supplements are the same.

Different forms of magnesium have different characteristics and levels of absorption.

Magnesium glycinate

Magnesium glycinate is often considered one of the best forms of magnesium for women. It combines magnesium with glycine, an amino acid involved in collagen and connective tissue structure.

Benefits may include: excellent absorption, being more gentle on the digestive system, supporting relaxation and sleep and its suitability for using long term. This is the form used in Advanced Bone Complex.

Magnesium citrate

Magnesium citrate is widely used and well absorbed. It is often chosen for general magnesium supplementation but may have a mild laxative effect in some individuals.

Magnesium oxide

Magnesium oxide contains a high percentage of elemental magnesium but is generally less well absorbed than glycinate or citrate.

It is commonly used in lower-cost magnesium supplements.

So which is best?

For women interested in healthy ageing, skin health, relaxation and bone support, magnesium glycinate is often considered one of the most effective and well-tolerated forms.

Best Magnesium for Women Women’s magnesium requirements can change throughout life. Magnesium becomes increasingly important during:

Perimenopause
Menopause
Periods of stress
Active lifestyles
Healthy ageing

When choosing a magnesium supplement, look for:

✔ A well-absorbed form such as magnesium glycinate

✔ Appropriate dosage

✔ Supporting nutrients

✔ A formula designed around your wider health goals

Why magnesium becomes more important during perimenopause and menopause

Magnesium becomes increasingly important during perimenopause and menopause as hormonal changes can affect many of the systems that rely on this essential mineral.

Fluctuating and declining oestrogen levels may contribute to symptoms such as poor sleep, increased stress, fatigue, mood changes and muscle tension, all of which can influence overall wellbeing and quality of life.

Magnesium plays a role in supporting normal psychological function, nervous system function and energy production, making it a valuable nutrient during this transition.

Magnesium also supports bone health, which becomes a growing priority after menopause. As oestrogen levels decline, bone turnover increases and women can begin to lose bone density more rapidly. Alongside nutrients such as vitamin D, vitamin K2 and calcium, magnesium helps support the maintenance of normal bones and contributes to the processes involved in healthy bone metabolism.

In addition, magnesium may support healthy ageing by helping the body cope with the effects of everyday stress and promoting restful sleep. Since sleep quality often declines during perimenopause and menopause, ensuring adequate magnesium intake through diet and supplementation can form an important part of a holistic approach to supporting wellbeing, resilience and vitality during midlife and beyond.
