Why do we use it in formulations? Because they’re magic, basically. Silica microspheres improve slip, reduce the oily feel of products, and help improve the appearance of the skin by diffusing light for a real-life airbrushing effect.
I use silica microspheres in a lot of eye makeup formulas because they improve the slip/glide of the product and help with oil control, which helps improve wear time.

I include silica microspheres in cream cosmetics and oil serums because they give the end product a beautiful dry-touch finish that is incredibly luxurious and feels very expensive. Try blending a drop or two of oil with a tiny sprinkle of silica microspheres and rubbing that into your hand to see what I mean!
