SODIUM PCA
Is SODIUM PCA safe for seborrheic dermatitis?
Sodium PCA is not automatically unsafe for seborrheic dermatitis and may help a formula hold water at the skin surface. It is a humectant and conditioning ingredient, not a proven treatment for the yeast or inflammation involved in seb derm.
No applicable evidence found for this page shows that Sodium PCA feeds Malassezia. A hydrating formula may feel helpful when skin is dry, but even humectant products can sting a damaged barrier or be paired with irritating ingredients. Judge the complete product and stop if discomfort repeatedly increases.

What is SODIUM PCA used for in skincare?
Sodium PCA is the sodium salt of pyrrolidone carboxylic acid, a component associated with the skin's natural moisturising factor. It attracts and holds water, helping skin or hair feel less dry. It is commonly combined with other humectants and emollients in moisturising formulas.
