After using a brush on a client, the store had some down time and I did a brisk-brush cleansing on the brushes so that they'll be cleaner and sanitized for the next client.
The cleanser at first, I was skeptical until I tried it. I used it again yesterday and falling in love with it, purchased a bottle the next day when I stopped by the counter to say Hi and to check on any job that I might have left behind.
While working on counter as a guest artist, I used the MAC brush cleanser in cleaning the brushes before applying it to a client and also to clean the brushes after the shift. She would even state that before a makeup artist does her makeup, she should be shown that the brushes are clean and free of dirt. As Thalia mentioned in her book, Belleza, Lessons in Lipgloss and Happiness, 'dirty brushes are like petri dishes'. One of the things I've learned and decided to take into heart is never to let a dirty brush near a client or model's face.
Being a makeup artist exposes me to a lot of clients and hence aside from making them beautiful, caring for their skin should be our priority.
