MINERALS FOR SKIN: HOW INSIDE OUT CARE CREATES LASTING RESULTS
Skincare often starts with what we apply. Serums, moisturisers, masks. But if we stop there, we are missing half the story. The health of your skin is deeply connected to what is happening internally, from the nutrients you absorb to the way your body handles stress.
Minerals are a key part of that bigger picture. You might not think about them beyond the occasional supplement or nutrition label, but these trace elements play an essential role in keeping your skin balanced, clear and resilient. When you support your skin from both the inside and the outside, the effects are more sustainable and more visible.

WHY MINERALS MAKE A DIFFERENCE?
Unlike vitamins, minerals are elements the body cannot produce. We get them through food, supplements and skincare. Once they are in the system, they quietly support hundreds of processes that directly affect skin health.
Inside the body, minerals influence hormone balance, immune function and the body’s ability to repair itself. They also help regulate oxidative stress, which can lead to early signs of ageing if left unchecked. On the skin’s surface, they support hydration, calm sensitivity and strengthen the outer layer that protects against environmental stress.
Even small mineral deficiencies can show up through breakouts, dullness, dryness or inflammation. That is why balance matters.
HOW INTERNAL MINERAL SUPPORT AFFECTS THE SKIN
Some minerals have particularly strong links to skin health. These support cell turnover, inflammation, collagen production and the skin’s ability to recover from daily stress.
You can get most of these from food. But sometimes, especially during periods of fatigue or hormonal changes, your body may need more consistent or concentrated support. This is where a high-quality supplement can help. Arbor’s TRINITY Multi-Nutrient is one example. TRINITY is a three-part multi-nutrient formula (Morning, Day, Night) that delivers targeted support throughout the day. Its Night Formula contains absorbable forms of key minerals that support recovery, better sleep and overall wellbeing. All of these contribute to healthier skin.
Here are a few to pay attention to.
Zinc
Zinc is involved in cell repair and plays a key role in immune regulation. It helps reduce inflammation and supports wound healing, making it particularly helpful for acne prone orreactive skin. Zinc also helps regulate oil production. A deficiency may lead to more frequent breakouts or slower skin recovery.
You can find zinc in foods like pumpkin seeds, oysters and beef.
It’s also included in TRINITY’s Night Formula as a highly absorbable bisglycinate form.
Magnesium
Magnesium is essential for over three hundred reactions in the body. These include processes related to stress response, sleep and energy production. It helps the body regulate cortisol, which can influence both hormone health and inflammation in the skin. Magnesium also supports DNA repair and reduces oxidative stress, which contributes to uneven tone and visible ageing.
Leafy greens, avocados and legumes are good sources of magnesium.
TRINITY delivers magnesium in two forms - malate in the Morning Formula and bisglycinate in the Night Formula for well-rounded support.
Selenium
Selenium is a trace mineral that supports antioxidant defence. It works alongside enzymes such as superoxide dismutase to help the body neutralise free radicals. Selenium also helps regulate inflammation, which is important for anyone dealing with sensitive skin or slow healing.
Food sources include eggs, tuna and almonds.
It’s included in TRINITY Night as selenomethionine - a bioavailable form.
Iron
Iron supports oxygen delivery throughout the body, including to skin cells. When iron levels are low, the skin can appear dull, pale or uneven. You might also notice dark circles becoming more pronounced. Iron is important for collagen production and general energy in the skin.
Lentils, spinach and red meat are all good dietary sources.
TRINITY includes gentle, well-tolerated iron bisglycinate in the Morning Formula - supporting energy and skin tone from the start of the day.
HOW TOPICAL MINERALS SUPPORT THE SKIN’S SURFACE?
Minerals do not only work internally. When used topically, they can help reinforce the skin barrier, improve hydration and reduce visible signs of irritation. Natural sources such as Dead Sea mud are especially rich in the kinds of minerals that support these functions.
The Dead Sea has a unique concentration of magnesium, calcium, potassium and other elements. These are easily absorbed through the skin and work directly on its surface. Products made with untreated Dead Sea mud, such as The Dead Sea Co. Mineral Mud Mask, deliver these minerals where they are needed most.
- Magnesium helps retain moisture and reduce visible redness
- Zinc supports healing and helps reduce inflammation around blemishes
- Calcium aids in cell turnover and strengthens the skin’s outer layer
- Potassium and sodium regulate hydration and support softness
- Iron promotes circulation, which can help brighten and balance tone
MINERALS AND OXIDATIVE STRESS
Oxidative stress happens when the body produces more free radicals than it can manage. These unstable molecules result from sun exposure, pollution, diet and stress. Over time, oxidative stress breaks down collagen, disrupts skin tone and accelerates signs of ageing.
Minerals such as zinc, selenium and magnesium help regulate this process. They support enzymes like superoxide dismutase that neutralise free radicals at a cellular level. When your mineral levels are well supported, your skin is better able to defend itself and recover.
HOW TO CREATE A MINERAL BASED ROUTINE
Looking after your skin from the inside and the outside does not need to be complicated. It is about building habits that work together.
Internal support
- Eat a varied, whole food diet rich in magnesium, zinc, selenium and iron
- Stay hydrated to help your body absorb nutrients
- Get enough essential fatty acids and key vitamins like A, C and D
- If needed, use a full-spectrum supplement such as TRINITY by Arbor to fill in any nutritional gaps
External care
- Use a mineral rich product like The Dead Sea Co. Mineral Mud Mask once or twice a week
- Follow with a moisturiser that supports your skin barrier
- Avoid over exfoliating or using harsh cleansers that can cause sensitivity
FINAL THOUGHTS ON MINERALS FOR SKIN HEALTH
Minerals may not be the most talked about part of skincare, but they are one of the most important. They help your skin recover, stay balanced and protect itself against stress. And when you are getting what you need, you can feel the difference.
Supporting your skin from both within and without is not about adding more. It is about understanding how the body and skin work together. With the right care on both fronts, your skin is in a much better position to thrive.

FAQs
Can I use mineral-rich skincare if I already take supplements?
Yes, definitely. They work in different ways. Supplements support your body and skin from within, especially if you’re low in something or feeling run down. Mineral-rich skincare focuses on your skin’s surface. It can help with things like calming redness, balancing oil and improving texture. Using both gives your skin full support from the inside and the outside.
Can minerals help with hormonal breakouts?
They can. Zinc and magnesium are both known for helping with inflammation and hormone balance. Zinc, in particular, is often recommended for acne because it helps regulate oil and supports healing. This is true whether you're using it topically or taking it as a supplement.
Is there a best time of day to take minerals?
There is. Your body has different needs throughout the day. Magnesium tends to be most helpful at night, as it supports sleep and recovery. Iron and zinc are better earlier in the day when your body is more active. That’s why Arbor’s TRINITY formula is split into morning, day and night capsules. It follows your natural rhythm and gives support when it’s most useful.
Can mineral-rich skincare take the place of retinol or acids?
Not really, but it can make them work better. Retinol and exfoliating acids do specific jobs like boosting collagen or clearing dead skin. Minerals support your skin barrier, which helps prevent irritation from those stronger treatments. If your skin is well cared for and calm, you’re more likely to get good results from actives without the side effects.
