Silica

Silica is an inorganic mineral compound (SiO2) that exists naturally as quartz or sand, though cosmetic-grade silica is typically synthetically produced as amorphous (non-crystalline) particles. In formulations, it serves as a multifunctional ingredient that absorbs oils and moisture, provides a matte finish, improves texture and slip, and acts as an anti-caking agent in powder products. Formulators choose silica for its ability to control shine, enhance product stability, improve spreadability, and create a soft-focus effect that minimizes the appearance of fine lines and pores, making it particularly valuable in makeup, sunscreens, and oil-control skincare products.
