Sodium PCA Beschreibung
Sodium PCA is the sodium salt of PCA (pyrrolidone carboxylic acid, a natural amino acid derivative). Sodium PCA occurs in skin is part of skin’s natural moisturising factor (NMF). As such, it and can also be found in both plant and animal tissue. Paula’s Choice Skincare does not use animal-derived sodium PCA. Its value comes from its function as a humectant, meaning it helps skin’s upper layers both draw in and retain moisture, resulting in a more supple, youthful appearance. Because of these abilities it’s a staple ingredient in many moisturisers, where it provides hydration without being thick or occlusive. It’s considered safe and non-irritating as used in skin care products, where concentrations typically range from 0.2–4%. It is sensitive to both light and heat, meaning products containing it should be packaged in opaque and air-restrictive containers.
