Can Magnesium help with skin aging?

Magnesium is an essential mineral involved in over 300 enzymatic reactions, including those relevant to skin health. Some studies suggest magnesium has anti-inflammatory properties and may support the skin barrier, which could theoretically help counteract premature skin aging. However, the evidence for a direct anti-aging effect of oral magnesium supplements is weak. Most data come from in vitro or observational studies, not large randomized controlled trials in humans. Topical magnesium (e.g., in creams) may have local soothing effects, but robust clinical evidence is lacking. Avoiding magnesium deficiency is important because deficiency can promote inflammation, but supplementing beyond normal requirements for skin rejuvenation is not evidence-based. Caution: high doses can cause diarrhea and gastrointestinal discomfort. For slowing skin aging, proven strategies like sun protection, antioxidants (vitamin C, E), and a balanced diet are more reliable. In summary: magnesium is important but not a miracle cure for skin aging.
