EWG hazard reflects the rating of the ingredient, not the real-world risk of a finished product — hazard depends on concentration. How we read these.
Data is aggregated from EWG, CIR, CosIng and the SkinCarisma community, and improves over time. Spot something off? See our methodology. This is general information, not medical advice.
