Why use makeup despite knowing it can be filled with harmful chemicals?

Hi girls, I'd like to hear your perspective about using makeup. I understand it is important to look groomed, but the more I read about makeup and it's harmful chemicals, I wonder why we don't have strict rules around it, and why educated women still choose well-known brands and not natural products. I know natural products are limited and it's hard to find a replacement for bronzer or eye shadow, but still I'm shocked at the health issues these cosmetics can cause.

I'd also like to understand, and introspect why I wear eye liner and lipstick too. I feel, I see other women at my workplace wear so much makeup, that if I don't wear the bare minimum atleast, id never be considered groomed. I hate it that I'm feeling this way.

I'm not trying to start an argument, but I'd like to know your genuine thoughts around this topic. Would you minimize make up use if everyone around you also used lesser?

Please don't get to me saying that air is polluted, water is polluted,etc. For things like Make up and Junk food, we do make a conscious choice while buying it and they're mostly avoidable too.
