What this is. Ingredient-label data from Open Beauty Facts (snapshot 2026-07-31), not laboratory testing. Coverage is crowdsourced, partial and Europe-weighted, so this is 16 of the 50 Syoss entries in that database, and US formulations often differ. A flagged ingredient is not automatically harmful — a gel thickener and a solid microbead are both synthetic polymers and are not the same risk.
