The first is the lamellar structure of mica: Mica is a rock-forming mineral, and mica used in cosmetics is usually scaly, as shown in the picture. The flake structure, if it can be covered with a layer of pits and pits on the surface of the skin, synthetic mica powder wholesale, so that the light can form a specular reflection instead of diffuse reflection without a fixed direction, so that the specularly reflected light can shine possible.

The second is that the light shining on mica has high reflection and low transmittance, so that the light will not pass through mica (not like glass), but will be reflected on the surface of mica powder.

Combining the above two characteristics of mica:

The definition of Shine itself is a contrast value between specular reflection and diffuse reflection. If all the light passes through the material or is diffusely reflected, it will not be able to form a specular reflection and form a gloss. The characteristics and structure of mica can form reflection instead of transmission. On the other hand, the sheet-like structure determines the specular reflection it can perform (imagine these countless small pieces of mica forming one by one on your face). mirror), so that the mica can form a good gloss. Mica powder is widely used in the cosmetic industry as pearlescent pigments to increase the brilliance of products, or on the surface of the skin, to brighten the complexion and give the skin a better radiance.
