Potassium PCA Beste Bevochtigingsmiddel Hydratatie Potassium PCA at a glance Mineral electrolyte that plays an influential role in skin’s natural moisturising factor Helps facilitate water pathways within skin, ensuring balanced hydration levels Aids in reinforcing skin’s barrier Helps optimises skin’s desquamation (shedding) process Potassium PCA description Potassium PCA is the potassium salt of PCA (pyrrolidone carboxylic acid), a substance that’s a natural part of skin’s intercellular matrix. Potassium PCA therefore plays an influential role in what’s known as skin’s natural moisturising factor (NMF). Potassium is one of the minerals that helps facilitate water pathways within skin, ensuring balanced hydration levels. In fact, when skin loses potassium, as it does when we sweat, it can look and feel drier. As an electrolyte, potassium plays a role in reinforcing skin’s barrier and in its desquamation (shedding) process. Potassium PCA has been deemed safe by the Cosmetic Ingredient Review Expert Panel. Their report surveyed products containing between 0.005-0.75% potassium PCA. Related ingredients: Magnesium PCA Calcium PCA PCA Natural Moisturizing Factor (NMF)
