While collagen, peptides, and antioxidants are often hailed as the skincare holy trinity, essential minerals deserve just as much attention. Take magnesium, for instance—it’s a trending mineral for good reason, supporting over 300 bodily functions, including cell hydration and collagen production.

But magnesium isn’t the only mineral that benefits your skin. Potassium, zinc, selenium, and sulfur also play vital roles in keeping your skin healthy and radiant.

Why Potassium Matters for Your Skin

A lack of potassium doesn’t just affect muscles and fluid balance—it can also show up on your skin. Potassium is crucial for maintaining hydration, and studies link low levels to dryness. Getting enough through your diet and using skincare products that contain it can make a real difference.

Dior’s scientific team recently reinforced this in a study on how micronutrient shortages affect skin longevity. They discovered that insufficient potassium doesn’t just lead to dehydration; it also robs skin of its glow. Potassium helps regulate water balance in skin cells, and without it, skin can show 40% more redness, 20% less hydration, and a staggering 97% drop in vitality. It’s essential for keeping skin supple, elastic, and resilient against stress and fatigue.

The Roles of Zinc, Selenium, and Sulfur

You might know zinc for boosting immunity or as a sunblock ingredient, but it does more. Dermatologist Patricia Ogilvie, founder of Munich’s Skinconcept clinic, recommends zinc—both in skincare and through diet or supplements—for its ability to speed up skin healing. This natural repair process slows with age, which is why children’s skin mends so much faster than adults’. Supporting this function can help delay aging, especially since how your skin responds to sun exposure depends on it.

Pharmacist and nutritionist Paula Martín Clares also champions minerals for skin health. Alongside zinc, she highlights sulfur for rejuvenating, hydrating, and softening skin, and selenium for its anti-aging benefits. She suggests eating asparagus, eggs, onions, and garlic for sulfur, and eggs, dairy, and mushrooms for selenium.
