I have severe acne so (when I wore makeup) I washed my foundation brushes after every use . I had three brushes so that it wouldn't be a problem if I didn't have time to wash one day. I used to not wash my eyeliner/eyeshadow brushes very often, but realized that my eyes were quite irritated all of the time. My lashes started growing back more and I stopped getting irritated after I started washing those once or twice a week. Oh, and just if anybody is interested, Bronner's soap has worked best for me for cleaning those things! I usually use Peppermint and Eucalyptus, but I don't think that matters. It works better than expensive brush cleansers (MAC and Sephora), dish soap, shampoo, and face wash. Quicker, too.
