most places are required to use disposable applicators, and sharpen pencils every time they use them it helps to keep down germs. i don't think there are any cases of someone catching something from a place that applied their makeup. if someone had something obvious i think that the people would tell them no I can't work on you. I have always cleaned my brushes with witch hazel it cleans them well and does not dry out the bristles.At the cosmetic counter at Saks, how do they cln their makeup tools? do they? should i be worried? went rcntly
I would hope that they use disposable applicators. The next time you use the counter you might bring this up. It is appropriate to be concerned about this, especially with the increased awareness of contagion.
