Pteria Margaritifera (Mother Of Pearl) Extract

What is Pteria Margaritifera (Mother Of Pearl) Extract?

Pteria margaritifera, known as the black-lip pearl oyster, yields mother of pearl extract from its nacre, the shimmering inner shell layer. Nacre consists mainly of layered calcium carbonate crystals bound by conchiolin, a protein matrix, along with amino acids and trace minerals like zinc and magnesium. In skincare products such as creams and serums, this marine-derived extract functions primarily in the conditioning category. It spreads evenly to create a lightweight film that diminishes surface roughness, enhances slip for easier application, and aids in locking in hydration by supporting the skin's barrier. This mechanism promotes a velvety texture and flexibility without greasiness, making it suitable for daily use in formulations targeting comfort and suppleness.
