Assalamu alaikum everyone

I've recently been told that there is halal and haram makeup, which I honestly never heard of before, I mean I know there halal food, but makeup??

They say some cosmetics have pork products and alcohol in them, which make them haram.

Now my question is, how do I know whether the makeup I use is haram or halal?
Do you know which makeup brands are haram for us Muslims?
It is written on the box? I have no idea!

And IF all those 'well known' brands are haram, do you know where they sell any halal makeup in the GULF?

please help, thanks.
