Magnesium PCA Beste Bevochtigingsmiddel Hydratatie Magnesium PCA at a glance A skin-replenishing mineral electrolyte Works with skin’s water channels to boost hydration and optimise moisture balance Helps strengthen skin’s barrier Deemed safe by the Cosmetic Ingredient Review Expert Panel Magnesium PCA description 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 moisturising 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. Linking magnesium with PCA helps to overcome this issue, allowing skin to benefit. Magnesium PCA works with skin’s aquaporins (water channels) to boost hydration and train skin to maintain its moisture balance. Magnesium PCA has been deemed safe by the Cosmetic Ingredient Review Expert Panel. Their report surveyed products containing between 0.1-0.18% magnesium PCA.
