Evidence check: Magnesium in the context of skin aging

Magnesium is an essential mineral involved in numerous cellular processes including DNA repair, collagen synthesis, and inflammation regulation—all relevant to skin aging. Some studies suggest that magnesium deficiency may impair skin barrier function and increase oxidative stress, potentially contributing to premature wrinkling. However, direct evidence for an anti-aging effect of magnesium in humans is limited. Most data come from in vitro or animal studies (mechanistic evidence). Clinical trials on oral supplementation specifically for skin aging are lacking. Topical magnesium may improve skin hydration, but effects on wrinkles or elasticity are not well established. At MyBody-X, magnesium is often measured as part of nutrient panels, but not specifically for skin aging. Maintaining normal magnesium levels is important for overall health, but anti-aging benefits from supplementation alone are not evidence-based. Caveat: High doses can cause diarrhea; caution in kidney disease. Overall: Mechanistic hints, but no strong human evidence for skin aging.
