Does anyone else have make up brush allergies? Or maybe it's the make up...?

I have the same problem! Kinda strange but I couldn't use synthetic brushes, something about them made my skin itchy and blotchy. I use natural hair brushes now and clean the regularly. If you have been using natural hair brushes try using synthetic or vice versa. My other suggestion would be to use q-tips and cottong to apply makeup. I did that before I changed brushes.
