Put Simply
Silica is an ingredient that helps keep powders smooth and prevents products from clumping together. It's generally safe to use on your skin, so you don't need to worry about it in your makeup or toothpaste. Just be cautious if you ever come across it in a dust form, as breathing it in can be harmful, but that's not something you'd usually encounter in cosmetic products.
Clinical Summary
Silica is commonly used in cosmetics as an anti-caking agent and absorbent. It is generally considered safe for topical use, with no significant health risks when used in product formulations designed for external application. Inhalation of crystalline silica, however, is known to be hazardous, but this form is typically not used in cosmetic products.
