ℹ️General Overview

For adults: hydrated silica used on the skin is usually low risk. It’s often used to make products thicker or to help scrub away dead skin. Most people can use products that contain it without problems, but some studies and safety reviews have raised questions that are not fully answered.

✅What to Do

Use products that contain hydrated silica as directed. Don’t use scrubs or powdered forms in a way that creates dust you might breathe in. Avoid using it on open cuts or badly broken skin. If you have sensitive skin, do a small patch test before regular use. Choose brands that share safety information or limit potentially risky ingredients.

Safety Risk Labels

This ingredient has the following documented risks:

Cancer: Animal studies reported tumor formation at low doses, according to the Cosmetic Ingredient Review. That means there is some evidence from lab animals that this ingredient can cause tumors under certain conditions.
Builds Up: Records from the U.S. National Library of Medicine list this ingredient as persistent and bioaccumulative in wildlife and humans, and the ingredient profile flags high persistence. That means it can accumulate in bodies and the environment over time.
Absorbed: The ingredient summary notes enhanced skin absorption, and the Cosmetic Ingredient Review flagged data gaps in safety assessments. This signals a chance the material can get through skin and into the body more easily than expected.
Banned: This ingredient is restricted in some product standards and cannot be used in certain verified products without clear safety proof; industry guidance (Cosmetic Ingredient Review) also recommends limits. That means some regulators or standards bodies limit its use.
Environmental: The U.S. National Library of Medicine and the ingredient profile identify persistence and bioaccumulation in wildlife, indicating a real potential for long-term environmental harm.
