Now I'm not one to wear cosmetics but just seeing reviews and how-to's is something I often like to do in the my spare time :) Here are some of my favourites (in no particular order)
The first guru that came to mind is my friend! I'm not being biased because I know her, but her reviews are really interesting and worth reading over even if you don't wear makeup :) Whenever she posts, I'm always excited to read them hehe. With a total of 8 posts, from what I've seen she's on her way to being a very popular product/makeup blogger x)
A long time blogger, she has posted reviews on everything from circle lenses to body creams to makeup. And did I mention her giveaways are huge? In fact she posted about one just yesterday.

Youtuber and blogger, this Korean girl is soooo pretty! Watching her upload vids with her husband is also very entertaining to watch because they're so cute together haha. Did I mention she recently got to meet 2PM and the Wonder Girls and talk/take pictures with them?!
