The ability of fumed silica to reduce shine in cosmetics is mainly due to its oil-absorbing properties. Here are some reasons:

Absorb oil: Fumed silica is highly lipophilic and can bind and absorb oil on the surface of the skin. It absorbs oil molecules and fixes them on its surface, thereby reducing the accumulation of oil on the skin's surface.

Controls Oil Production: Fumed silica also reduces shine by regulating the skin's oil production. It can interact with the oil on the surface of the skin, reduce the excessive secretion of oil, and keep the oil secretion of the skin at an appropriate level.

Regulating skin luster: Fumed silica has certain light-scattering characteristics, which can evenly scatter light and reduce the reflection of light on the skin surface, thereby reducing the appearance of oily shine. It makes skin look softer and more natural, reducing the shine effect of oil on the skin's surface.

Control Humidity: Fumed silica also has hygroscopic properties, which can absorb excess moisture and regulate the humidity in the product. By controlling the humidity, the oxidation of grease and the formation of oxidation products can be reduced, further reducing the appearance of shine.

To sum up, as an ingredient in cosmetics, fumed silica has the characteristics of absorbing oil, controlling oil secretion, regulating skin luster, and controlling humidity. makeup effect. However, the specific shine control effect may also be affected by factors such as product formulation, application method and individual skin type.
