Fumed silica is commonly used as a functional ingredient in the cosmetics industry. Its applications are mainly reflected in the following aspects:

Oil-absorbing and shine-controlling agent: Fumed silica has good oil-absorbing properties, so it is often added to cosmetics, such as flour, loose powder, etc., to absorb oil on the skin, help control shine, and make makeup last longer.

Thickener: Due to the fine particle properties of fumed silica, it can be used as a thickener to improve the texture of cosmetics, making them smoother and easier to apply.

Improve the fit: Fumed silica can form a thin film on the skin surface to improve the fit between cosmetics and skin, making makeup more natural.

Optical effects: Due to the optical properties of its fine particles, fumed silica can be used to create cosmetics with a soft focus effect, such as soft focus foundation, which can cover skin imperfections and make skin tone more even.

It should be noted that although the use of fumed silica in cosmetics is common, some people prefer to choose products that do not contain such ingredients in some natural and mineral cosmetics. Therefore, specific usage may vary depending on product type and personal preference.
