What is silica? In skincare, silica is a multi-functional ingredient: it works both as a texture-regulating helper and as an active ingredient with real benefits for skin.
What is silica used for, exactly? Here are its main functions:
• It acts as a gentle abrasive. You'll find silica in toothpaste and face and body scrubs, where its particles have no sharp edges, so they gently buff away dead skin cells and buildup without damaging skin or tooth enamel.
• It mattifies and thickens. In makeup like powders and foundations, silica gives that smooth, matte finish and silky feel on skin. In creams and lotions, it acts as a thickener and stabilizer, keeping the formula from separating while also helping control shine.
