Is it harmful to use eye shadow with antimony in it?

Yes, using eyeshadow that contains antimony can be harmful. Antimony is a toxic heavy metal that may cause skin irritation, allergic reactions, and long-term health issues with prolonged exposure. It is advisable to check cosmetics for harmful substances and opt for products that are free from heavy metals to ensure safety. Always consult with a dermatologist or healthcare professional if you have concerns about specific ingredients.
