The main difference between cosmetic silica and ordinary silica lies in its form and role in cosmetics, which can improve the performance and appearance of products. Cosmetic silica can prevent powdery cosmetics from clumping, improve their dispersibility and stability.

Silicon dioxide is widely used in various personal care products, such as skincare products, sunscreen, makeup, antiperspirants, hair care products, shower gel, facial cleansers, etc. The particle shape of ordinary silica is spherical or nearly spherical, and the particle size is usually 1-100 micrometers. It will scatter and refract light under illumination, with limited reflectivity and covering power.
