I fel that continuous education is VERY important. Rather you can go to workshops, go to a convention, or simply spend a few hours a week watching pros on YouTube...anything helps to stay on trend
. I still meet a lot of MUAs that don't know about the wonder that is Beauty So Clean or the importance of primers. Rather you use them or not I still feel like it's at least good to know they exists so that you can answer your client's questions about them.
I'm extremely lucky in the fact that I work in the corporate office of a major beauty retailer. My job is literally recommending and reading about new products along with how to use them; because of that I don't really go to a lot of workshops.
