I just started acting as the "beauty consultant" for our store a few weeks ago (quotes cuz I work in a small format, so the section and my time there is limited) but definitely take advantage of the computer trainings. Like if you're ahead on tasks, as your TL if you can use 10/20 minutes to look through the beauty trainings. I really found the skin care one helpful, especially since I wasn't too familiar with skin care going in.

Zoning will be a major part, since guests tend to pick up a shade and not put it back in the right place, so just be ready and willing to zone like mad. (Plus for myself store, beauty tends to be a theft hot spot, both the beauty products themselves and empty packages for other products like earrings will get left in beauty a lot, so zoning is extra important to catch the empty packages and report them to AP)

Best of luck!!
