Heavy Metals in Cosmetics Limits
Heavy metals in cosmetics limits are regulated or guided by multiple jurisdictions, including the United States and the European Union. While some metals may occur as trace impurities, excessive levels can present safety and regulatory concerns.
Common metals tested include:

- Cadmium
- Nickel
Why Heavy Metals Testing Is Important
Heavy metals may enter formulations through:
- Raw material contamination
- Pigments and colorants
- Natural extracts

Although complete absence may not always be technically feasible, levels must remain within accepted safety thresholds.
