Science & Benefits

Potassium PCA is the potassium salt of Pyrrolidone Carboxylic Acid (PCA), a key component of the skin's Natural Moisturizing Factor (NMF). While Sodium PCA is more common, the Potassium version is prized for its ability to maintain the skin's osmotic pressure and electrolyte balance. It acts as a bio-mimetic humectant, pulling moisture into the stratum corneum and holding it there without any greasy residue. It is completely non-comedogenic and serves to stabilize the skin barrier, making it a 'bulletproof' choice for acne-prone skin that is currently being treated with drying agents like retinoids or benzoyl peroxide.
