Makeup Revolution is a brand that I've been curious about for a while, so I sent them an email to find out if they were cruelty-free and if they had any products suitable for vegans. Here is the reply they sent me:
Thanks for the queries.
We can confirm that we do not test our finished products nor ingredients on animals and neither do any third parties (and we are not owned by a parent company).
We do not sell in China.
We cannot claim products which are vegan friendly but we are looking into these claims next year as we get a lot of requests on this.
I'm happy to say that Makeup Revolution are cruelty-free, and although they don't currently have any details on which products are vegan, they do have an ingredients page on their website, so you're free to check if the product you are thinking of buying contains any animal derived ingredients.
