I think there is a huge amount of cognitive dissonance between some consumers and their use of weird and wonderful "ingredients", waving away the potential risks because they love the product / smell / packaging / feel on their skin / effect on how they look etc.
Many people can't accept that some commonly used ingredients could be potentially dangerous. I think some commonly used ingredients will at some point be shown to be damaging in a similar way as UPF are starting to be shown as (which has taken decades to get to this stage).
Anti-perspirant is a case in point. You will still get some people claiming there is no correlation to breast cancer, even though studies like the below one have recently come to light (published in the Lancet).

"Previous studies regarding breast cancer (BC) risk and underarm cosmetic products (UCPs) with aluminum salts have shown conflicting results. Here we provide comprehensive information about the use of UCPs and aluminum measurements in breast cancer patients and healthy individuals. The findings suggest that the frequent use of UCPs lead to an accumulation of aluminum in breast tissue. We observed an increased risk for BC in women who reported to use UCPs more than once daily starting at an age < 30 years. We recommend that particularly women at younger ages should be careful using UCPs and avoid its excessive use."
How many other supposedly "safe" ingredients will come to light as potentially dangerous / cancer causing? I believe people should show special caution when considering which products to use, even if they are touted as "safe" in small quantities etc.
Let's also face up to the fact that cosmetics manufacturers and so on want to sell their product, make a profit and are not necessarily 100% ethical. In the same way as multinational food corporations and producers of UPF are not ethical and market their products in an underhanded way.
