Maybe you need to do a little more research before defending your precious cosmetic culture and calling any criticism "scaremongering bullshit".
EDC is a scientifically proven component of some cosmetics. It's in so much literature. It's not "crazy". Now, whether or not the levels present in make-up would actually make a difference in reality is a separate issue, and at current standards without aggregate factors, it probably isn't a pressing concern in developed countries. But not every country is the USA or in the EU.

-- Potential carcinogens in makeup cosmetics
Balweirz et al. Int J Environ Res Public Health. 2023 Mar; 20(6): 4780. Published online 2023 Mar 8. doi: 10.3390/ijerph20064780
Maybe OP should have said "potential" carcinogens, but considering the presence of these chemicals is not in question, I don't see the point in playing such pendant games. The use of potential is only because the chemicals themselves have not been completely proven to be carcinogenic, although it's widely understood that they play some role.
The fact is nobody can say definitely whether cosmetics are carcinogenic or not. So, while OP can't really claim it is true, nobody can disprove it either. The FDA and other regulatory agencies tolerate a certain level of harmful chemicals in cosmetics, but claim it is UNLIKELY to cause "serious health issues". The word "unlikely" is important. They cannot guarantee it won't, nor can OP guarantee it will (especially since we don't exist in a vacuum and often carcinogenic triggers are multifactorial.) But the potential exists on some level. And how that is even acceptable to women is insane. "Well, I'll have a little bit of carcinogens in my makeup, as a treat!" No need to boycott or insist multinational makeup companies do better for us. Just keep slathering on the chemicals like good girls.
Even the FDA says there are heavy metals in cosmetics, just that it's not enough to cause serious health issues.
The language used here is very telling, but that's a whole other issue. But the FDA is hedging quite heavily. And then there's the issue that a lot of FDA "rules" are actually just recommendations, and the FDA is not a perfect organization either. They're the ones who greenlit OxyContin without proper oversight.
Now, what you are forgetting or simply not aware of, not every country in the world follows the EU or WHO guidelines on heavy metals (or carcinogens) in cosmetics. Only the USA has the FDA. So, while maybe your make up in an American Walmart is technically "safe", that doesn't mean some woman in India is getting the same standard of safety in her knockoff Revlon lipstick (GMPs and toxicology of cosmetics in developing or underdeveloped nations is actually a subject of focus for scientists, health officials, and feminists). This is about more than just YOU in your FDA-sheltered country. You'll notice the world is quite large and this is about all women who use makeup, not just American or EU ones. Calling it "scaremongering bullshit" is one way to say you don't give a shit about life for women outside your protected little American bubble.
Finally, this is all ignoring the impact cosmetics have environmentally, when sure, on a personal use level maybe they're fine, but when they get dumped in oceans and dumps in large amounts, those trace amounts begin to add up.
Like, I get that fear-mongering, exaggeration, and hyperbole using misuses of scientific literature is not the way to go about getting a real message out, but OPs post really wasn't exceptionally far off, especially if you recognize that not all countries maintain the same manufacturing practices or health standards, and women use makeup there as well. Nothing she wrote was all-caps CRAZY. And sometimes people need to hear worst case scenarios cuz saying things like "you might get a sty" is not going to bother them at all, but they need to be concerned and fully informed about the potentially toxic chemicals in the products they put on their skin, get in their eyes and mouths, and can get into their lungs and bloodstreams.
There should be no "safe amount". It should be zero. And women should demand zero if they insist on using makeup. (Or just stop with makeup and that's even better.)
