It tests on animals T.T
I'm not against it but a guy friend of mine says that he thinks girls that wear too much makeup seem like they don't like the way the look = no confidence which is key to a guys heart. I'm pretty sure everyone just thinks their 'fake' and maybe just jealous on how they can pull it off?
edit
and for that its bad for your skin bs, some makeup even is good for your skin- like my foundation (and no im not advertising for it) that I have, its called Afterglow, its organic, minerals, and has things good for your skin like vitamin e and etc. plus no animal testing. yeah i guess some crappy brands can make your skin worse but you can avoid that so theres no issue there for me.
Honestly, I think that if people cared about how fake someone looks with makeup they must be implying that looks don't even matter so they shouldn't even care in the first place. Although personality does matter more than looks first impressions are important!
