Science
Mechanism of Action
This advanced chelated form of magnesium ensures optimal delivery to skin cells, where it orchestrates crucial repair and regeneration processes, including DNA replication and recovery from damage. It is vital for maintaining skin moisture, supporting a robust skin barrier to significantly minimize trans-epidermal water loss (TEWL). As a potent antioxidant, Magnesium Glycinate protects cellular structures from oxidative stress, particularly that induced by UV exposure, which can otherwise lead to hyperpigmentation. Its soothing properties are instrumental in calming redness and alleviating sensitivity, while also assisting in sebum regulation, proving beneficial for acne-prone skin. The inherent glycine component provides synergistic support for collagen synthesis, enhancing skin elasticity and firmness. Beyond these, topical magnesium application has been shown to boost skin hydration and elevate filaggrin levels, a protein critical for stratum corneum function. Further, it exhibits anti-inflammatory effects by inhibiting epidermal stratum corneum cell overproduction, potentially mitigating psoriatic lesions, and modulating the antigen-presenting capacity of Langerhans cells.

Key findings
- 01 While specific clinical studies on topical Magnesium Glycinate are not extensively reported, research on broader topical magnesium applications highlights significant dermal benefits. A 2% magnesium cream demonstrated improvement in diaper dermatitis and rash in pediatric subjects.
- 02 Separately, immersion in a magnesium-rich Dead Sea salt solution notably reduced skin redness and roughness in atopic dry skin, concurrently improving skin barrier function and overall hydration.
Transparency
Dusting Analysis
Magnesium Glycinate is recognized for its scientifically supported skin benefits and is not typically used as a 'dusting' ingredient. Its inclusion in formulations is based on its functional properties, not merely for marketing claims without substantial efficacy.

Formulation
Stability
For optimal topical product integration and skin compatibility, Magnesium Glycinate is typically dissolved in the water phase during emulsion preparation, with the final product pH balanced within the physiologically appropriate range of 5.5-6.5.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has affirmed the safety of amino acids and their simple salts, including Magnesium Glycinate, for cosmetic use, concluding they are neither dermal irritants nor sensitizers. European Union regulations also permit its use. It is crucial to distinguish this from FDA warnings concerning *unregistered food supplements* containing Magnesium Glycinate, which pertain to product registration status, not the intrinsic safety of the ingredient in cosmetics.
