In no particular order.
Yaz - she's a Muslim makeup artists in England, I believe, and stunningly gorgeous. She always wears the hijab in her videos, which is how you can easily tell her apart. The eyes and skin on that woman are to die for and none of the other TouTube gurus come close to comparing to her. Definitely my number 1 favorite of all time. She is sometimes criticized by other Muslim women, which makes her even more a favorite of mine. The woman has guts AND is really good at what she does.
Pursebuzz - one of the first I came across when I started watching YouTube MUAs
Pixiwoo - but they occasionally annoy me and can sometimes seem pretentious as well

Makeup Geek - to me she seems like she would be genuinely nice in person, but I could be wrong. Not the 'plaster on a smile and pretend to be nice' BS, but really a nice person deep down.
