Science
Mechanism of Action
Magnesium Chloride functions as a potent humectant, drawing and retaining moisture to deeply hydrate the skin, thereby enhancing elasticity and preventing transepidermal water loss. It actively supports the recovery of the epidermal barrier and elevates filaggrin levels, a protein critical for robust skin barrier function. Its inherent soothing and anti-inflammatory properties effectively mitigate redness and irritation, rendering it particularly beneficial for sensitive and acne-prone skin. Beyond surface effects, magnesium is crucial for cellular vitality, aiding enzymes involved in DNA repair, inhibiting epidermal differentiation, and promoting cell migration, suggesting benefits for early wound healing. Under acidic conditions, it exhibits antibacterial, antiseptic, and bactericidal activity, assisting in skin detoxification and reducing microbial colonization for a clearer complexion.

Key findings
- 01 A 12-week transdermal application resulted in an average cellular magnesium increase of 59.5% in 89% of test subjects, with some achieving over 200% elevation. This method was observed to be 5 times faster than oral intake for comparable results.
- 02 Topical compositions containing Magnesium Chloride were shown to effectively treat moderate-to-severe inflammatory, non-nodular acne vulgaris, reducing inflammatory lesion counts by at least 25% or 50% when applied daily over 6-52 weeks, demonstrating minimal to no irritation potential.
- 03 A precisely formulated magnesium cream exhibited statistically significant transdermal permeation of magnesium across human cadaver skin within 24 hours, outperforming a standard magnesium chloride solution.

Dusting Analysis
No data is available to indicate that Magnesium Chloride is commonly subjected to 'dusting' or used at sub-efficacious concentrations in cosmetic formulations for its active benefits.
The Formula
Formulation
Stability
Magnesium Chloride is optimally stable within a pH range of approximately 5.0 to 7.5, though effective within a broader range of 3.5 to 8.0 when diluted 1:9 in water. It exhibits antiseptic properties in acidic conditions. Furthermore, it acts as a valuable stabilizer for emulsions and nanoparticles, preventing component separation and ensuring product homogeneity and efficacy.
Safety
Safety Profile
Magnesium Chloride is classified as Generally Recognized As Safe (GRAS) by the FDA for direct food contact and is generally considered safe for cosmetic applications without specific concentration limitations. While the Cosmetic Ingredient Review (CIR) Expert Panel has not issued a dedicated safety assessment for Magnesium Chloride, a related compound, Magnesium Sulfate, was deemed safe when formulated non-irritating. Data indicates a low potential for skin irritation and toxicity, making it a preferred choice in many formulations.
