Clean your brushes!
Cleaning your brushes is so important. This was something that I NEVER did for so long, but now I try to make this my Sunday ritual. Think about all of the bacteria living in your brushes and then spreading that gunk all over your face. I use Dr. Bronner's Tea Tree Liquid Soap to clean my brushes. It is best to lay the brushes level while drying them, so that the excess water does not ruin handle of the brush. I love applying makeup with freshly washed brushes.
