What this means for you

The chemical-hazard rating is what drives the score down. The FDA has repeatedly warned that traditional kohl and kajal can be largely lead salts, and their use near the eye is linked to raised blood-lead levels, especially in children. Only cosmetics with an FDA-approved colour additive list are safe substitutes.
