I'm the kind of person who thinks we have become way too germaphobic -- getting out of control with hand sanitizers, anti-bacterial soaps, etc. However, I do agree that makeup applicators should be washed occasionally. my question is, how often do you really need to do it? It's a pain in the butt.
specifically, the makeup I use is a loose powder applied with a puff, stored in the powder container. my face is clean when I use it, but I can't help but think about how the puff is not getting any air circulation.
back in the old days I used to never wash puffs, I just waited for the powder to run out and then threw it away. I never had problems with infections or anything, but I do have mild adult acne.
I'm currently washing them once a week now, and my acne seems better, but it might be just a coincidence (there are other things that could have caused the improvement). I'm lazy. once a week seems too often.
