100% natural complex with an amphiphilic structure. It is composed of a branched octyldodecyl ester and L-Pyrrolidone Carboxyl Acid or L-PCA, obtained by cyclization of L-glutamic acid, an amino acid from plant origin. As a major physiological component of the Natural Moisturizing Factor (NMF), this lipophilic PCA offers optimal bioavailability and easy absorption into the epidermis. Perfect for makeup and skincare, this active ingredient provides a rich, silky feel without leaving a sticky effect. It enhances skin’s integrity and strengthens its barrier function.
