Are nyx cosmetics halal

If you were looking for makeup that is definitely Halal I would try to stick to Vegan cosmetics, as you can be sure that these definitely contain no animal products, so it becomes a non-issue.

Urban Decay have a large range of vegan cosmetics, as well as most Mineral makeup companies.

One product that makes makeup not vegan but would be OK for you is Carmine, it is a red pigment that comes from insects (beetles I think).

Hope this helps.
