Magnesium PCA is the magnesium salt of PCA (pyrrolidone carboxylic acid), which is part of skin’s intercellular matrix. Magnesium PCA therefore plays an influential role in what’s known as skin’s natural moisturizing factor.
As an electrolyte mineral, magnesium plays a role in enhancing skin hydration and barrier repair. It also influences how skin cells move through skin’s surface layers, how they shed, and how skin responds to external stimuli.
Interestingly, pure magnesium and some forms such as magnesium chloride have a difficult time penetrating skin; however, linking magnesium with PCA or lactic acid (as in magnesium lactate) helps to overcome this issue, allowing skin to benefit.
