Magnesium Chloride
Ingredient Info
Magnesium chloride is a mineral salt form of magnesium that can be absorbed through the skin. In skincare, it's typically used as a mineral supplement ingredient, with some evidence suggesting it may help maintain magnesium levels in the body and support muscle function.
Benefits
- May help maintain healthy magnesium levels when applied topically
- Preliminary evidence suggests it may help reduce muscle cramping
- Well-tolerated mineral ingredient with minimal skin irritation
Potential concerns
- Limited evidence for direct skincare benefits (wrinkles, hydration, acne)
- May cause drying or mild irritation in sensitive individuals
- Research on topical absorption in healthy skin is sparse
Science: A 2024 clinical pilot study found topical magnesium chloride spray helped maintain serum magnesium levels and reduced muscle cramps in patients with specific medical conditions. However, this research focused on systemic absorption via spray application in unwell populations, not cosmetic skincare benefits in healthy skin. General skincare efficacy data is limited.
