Since we’re living in a society where it’s apparantly totally okay to produce goods that is hazardous to ourselves and our environment and not tell us about it, I think we have some sort of obligation to educate ourselves in what it is we are buying and what is in the products.
Sometimes it’s really hard to get the information but at least in the market of cosmetics and other so called beauty products there is The Cosmetic Database where you can easily research products before you decide on your purchase, or check the ones you are using to know if (how much…) they are hurting your body and surroundings. Make up and body products are, as well as clothes which you should also be careful with when it comes to chemicals, something you have in direct contact with your skin for long periods of time, often every day. So it’s worth taking your time to research what you are using and consider if it’s really worth it at all.

Quick example of searching for Max Factor which was the first I could think of. Then they will also list what chemicals is in each product produced by the company.
