I only remember littlepinkstars from your list!
Here's a few from back in my day that have disappeared (been watching beauty gurus since around 2010)
-SWalkerMakeup (shes made a few comebacks and then buggered off again! She was my absolute favourite back in the day)
-Gemsmaquillage (now Hello Gemma, makes the very occasional sporadic video, I follow her on Instagram and she's one of my favourite online people but I miss her videos)
-MissPrincessPancake (not even sure I've got her username right! Really lovely bubbly woman who was a primary school teacher I think, with one or two cats? So lovely and watchable)
-sirvinya (she was boring but oddly compelling! Think she was inspired heavily by Lauren Luke/panacea81, seemed to buy/hoard a lot of makeup and do a lot of tutorials that were mainly eyeshadow focused)
-CosmeticsCharlotte (she was so sweet and down to earth, I remember she took her channel down a fitness journey route which I also enjoyed but she seems to have fully vanished now)
-hollyYMBB (loved her channel and blog, I remember she always used to reply to my blog comments and it felt like such a big deal haha)
-camiloveskiwi (she had such a cool air about her, really chilled out and not afraid to be honest about things)
I'm sure there's tons more, I'll come back to this thread when I think of them! A few of the people I've been watching since 2010 still upload, like FleurDeForce and BeautyCrush!
